-Subject: [PATCH] kbuild: add macro for controlling warnings to
- linux/compiler.h
-
-I have occasionally run into a situation where it would make sense to
-control a compiler warning from a source file rather than doing so from
-a Makefile using the $(cc-disable-warning, ...) or $(cc-option, ...)
-helpers.
-
-The approach here is similar to what glibc uses, using __diag() and
-related macros to encapsulate a _Pragma("GCC diagnostic ...") statement
-that gets turned into the respective "#pragma GCC diagnostic ..." by
-the preprocessor when the macro gets expanded.
-
-Like glibc, I also have an argument to pass the affected compiler
-version, but decided to actually evaluate that one. For now, this
-supports GCC_4_6, GCC_4_7, GCC_4_8, GCC_4_9, GCC_5, GCC_6, GCC_7,
-GCC_8 and GCC_9. Adding support for CLANG_5 and other interesting
-versions is straightforward here. GNU compilers starting with gcc-4.2
-could support it in principle, but "#pragma GCC diagnostic push"
-was only added in gcc-4.6, so it seems simpler to not deal with those
-at all. The same versions show a large number of warnings already,
-so it seems easier to just leave it at that and not do a more
-fine-grained control for them.
-
-The use cases I found so far include:
-
-- turning off the gcc-8 -Wattribute-alias warning inside of the
- SYSCALL_DEFINEx() macro without having to do it globally.
-
-- Reducing the build time for a simple re-make after a change,
- once we move the warnings from ./Makefile and
- ./scripts/Makefile.extrawarn into linux/compiler.h
-
-- More control over the warnings based on other configurations,
- using preprocessor syntax instead of Makefile syntax. This should make
- it easier for the average developer to understand and change things.
-
-- Adding an easy way to turn the W=1 option on unconditionally
- for a subdirectory or a specific file. This has been requested
- by several developers in the past that want to have their subsystems
- W=1 clean.
-
-- Integrating clang better into the build systems. Clang supports
- more warnings than GCC, and we probably want to classify them
- as default, W=1, W=2 etc, but there are cases in which the
- warnings should be classified differently due to excessive false
- positives from one or the other compiler.
-
-- Adding a way to turn the default warnings into errors (e.g. using
- a new "make E=0" tag) while not also turning the W=1 warnings into
- errors.
-
-This patch for now just adds the minimal infrastructure in order to
-do the first of the list above. As the #pragma GCC diagnostic
-takes precedence over command line options, the next step would be
-to convert a lot of the individual Makefiles that set nonstandard
-options to use __diag() instead.
-
-[paul.burton@mips.com:
- - Rebase atop current master.
- - Add __diag_GCC, or more generally __diag_<compiler>, abstraction to
- avoid code outside of linux/compiler-gcc.h needing to duplicate
- knowledge about different GCC versions.
- - Add a comment argument to __diag_{ignore,warn,error} which isn't
- used in the expansion of the macros but serves to push people to
- document the reason for using them - per feedback from Kees Cook.
- - Translate severity to GCC-specific pragmas in linux/compiler-gcc.h
- rather than using GCC-specific in linux/compiler_types.h.
- - Drop all but GCC 8 macros, since we only need to define macros for
- versions that we need to introduce pragmas for, and as of this
- series that's just GCC 8.
- - Capitalize comments in linux/compiler-gcc.h to match the style of
- the rest of the file.
- - Line up macro definitions with tabs in linux/compiler-gcc.h.]

-
-gcc-8 warns for every single definition of a system call entry
-point, e.g.:
-
-include/linux/compat.h:56:18: error: 'compat_sys_rt_sigprocmask' alias between functions of incompatible types 'long int(int, compat_sigset_t *, compat_sigset_t *, compat_size_t)' {aka 'long int(int, struct <anonymous> *, struct <anonymous> *, unsigned int)'} and 'long int(long int, long int, long int, long int)' [-Werror=attribute-alias]
- asmlinkage long compat_sys##name(__MAP(x,__SC_DECL,__VA_ARGS__))\
- ^~~~~~~~~~
-include/linux/compat.h:45:2: note: in expansion of macro 'COMPAT_SYSCALL_DEFINEx'
- COMPAT_SYSCALL_DEFINEx(4, _##name, __VA_ARGS__)
- ^~~~~~~~~~~~~~~~~~~~~~
-kernel/signal.c:2601:1: note: in expansion of macro 'COMPAT_SYSCALL_DEFINE4'
- COMPAT_SYSCALL_DEFINE4(rt_sigprocmask, int, how, compat_sigset_t __user *, nset,
- ^~~~~~~~~~~~~~~~~~~~~~
-include/linux/compat.h:60:18: note: aliased declaration here
- asmlinkage long compat_SyS##name(__MAP(x,__SC_LONG,__VA_ARGS__))\
- ^~~~~~~~~~
-
-The new warning seems reasonable in principle, but it doesn't
-help us here, since we rely on the type mismatch to sanitize the
-system call arguments. After I reported this as GCC PR82435, a new
--Wno-attribute-alias option was added that could be used to turn the
-warning off globally on the command line, but I'd prefer to do it a
-little more fine-grained.
-
-Interestingly, turning a warning off and on again inside of
-a single macro doesn't always work, in this case I had to add
-an extra statement inbetween and decided to copy the __SC_TEST
-one from the native syscall to the compat syscall macro. See
-https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83256 for more details
-about this.
-
-[paul.burton@mips.com:
- - Rebase atop current master.
- - Split GCC & version arguments to __diag_ignore() in order to match
- changes to the preceding patch.
- - Add the comment argument to match the preceding patch.]

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-I had many reports that TSQ logic breaks wifi aggregation.
-
-Current logic is to allow up to 1 ms of bytes to be queued into qdisc
-and drivers queues.
-
-But Wifi aggregation needs a bigger budget to allow bigger rates to
-be discovered by various TCP Congestion Controls algorithms.
-
-This patch adds an extra socket field, allowing wifi drivers to select
-another log scale to derive TCP Small Queue credit from current pacing
-rate.
-
-Initial value is 10, meaning that this patch does not change current
-behavior.
-
-We expect wifi drivers to set this field to smaller values (tests have
-been done with values from 6 to 9)
-
-They would have to use following template :
-
-if (skb->sk && skb->sk->sk_pacing_shift != MY_PACING_SHIFT)
- skb->sk->sk_pacing_shift = MY_PACING_SHIFT;

-Subject: [PATCH] usb: dwc2: dwc2_vbus_supply_init: fix error check
-
-devm_regulator_get_optional returns -ENODEV if the regulator isn't
-there, so if that's the case we have to make sure not to leave -ENODEV
-in the regulator pointer.
-
-Also, make sure we return 0 in that case, but correctly propagate any
-other errors. Also propagate the error from _dwc2_hcd_start.
-
-Fixes: 531ef5ebea96 ("usb: dwc2: add support for host mode external vbus supply")

- mtd_add_device_partitions()
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This change is a small cleanup of mtd_device_parse_register(). When
-using MTD_PARTITIONED_MASTER it makes sure a master MTD is registered
-before dealing with partitions. The advantage of this is not mixing
-code handling master MTD with code handling partitions.
-
-This commit doesn't change any behavior except from a slightly different
-failure code path. The new code may need to call del_mtd_device when
-something goes wrong.

-
-With this commit proper functions are called directly from the

-Subject: [PATCH] mtd: partitions: add of_match_table parser matching for the
- "ofpart" type
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-In order to properly support compatibility strings as described in the
-bindings/mtd/partition.txt "ofpart" type should be treated as an
-indication for looking into OF. MTD should check "compatible" property
-and search for a matching parser rather than blindly trying the one
-supporting "fixed-partitions".
-
-It also means that existing "fixed-partitions" parser should get renamed
-to use a more meaningful name.
-
-This commit achievies that aim by introducing a new mtd_part_of_parse().
-It works by looking for a matching parser for every string in the
-"compatibility" property (starting with the most specific one).
-
-Please note that driver-specified parsers still take a precedence. It's
-assumed that driver providing a parser type has a good reason for that
-(e.g. having platform data with device-specific info). Also doing
-otherwise could break existing setups. The same applies to using default
-parsers (including "cmdlinepart") as some overwrite DT data with cmdline
-argument.
-
-Partition parsers can now provide an of_match_table to enable
-flash<-->parser matching via device tree as documented in the
-mtd/partition.txt.
-
-This support is currently limited to built-in parsers as it uses
-request_module() and friends. This should be sufficient for most cases
-though as compiling parsers as modules isn't a common choice.

- parse_mtd_partitions()
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This commit slightly simplifies the code. Every parse_mtd_partitions()
-caller (out of two existing ones) had to add partitions & cleanup parser
-on its own. This moves that responsibility into the function.
-
-That change also allows dropping struct mtd_partitions argument.
-
-There is one minor behavior change caused by this cleanup. If
-parse_mtd_partitions() fails to add partitions (add_mtd_partitions()
-return an error) then mtd_device_parse_register() will still try to
-add (register) fallback partitions. It's a real corner case affecting
-one of uncommon error paths and shouldn't cause any harm.

-Subject: [PATCH] mtd: bcm47xxpart: improve handling TRX partition size
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-When bcm47xxpart finds a TRX partition (container) it's supposed to jump
-to the end of it and keep looking for more partitions. TRX and its
-subpartitions are handled by a separate parser.
-
-The problem with old code was relying on the length specified in a TRX
-header. That isn't reliable as TRX is commonly modified to have checksum
-cover only non-changing subpartitions. Otherwise modifying e.g. a rootfs
-would result in CRC32 mismatch and bootloader refusing to boot a
-firmware.
-
-Fix it by trying better to figure out a real TRX size. We can securely
-assume that TRX has to cover all subpartitions and the last one is at
-least of a block size in size. Then compare it with a length field.
-
-This makes code more optimal & reliable thanks to skipping data that
-shouldn't be parsed.

-Subject: [PATCH] mtd: partitions: use DT info for parsing partitions with
- "compatible" prop
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-So far only flash devices could be described in DT regarding partitions
-parsing. That could be done with "partitions" subnode and a proper
-"compatible" string.
-
-Some devices may use hierarchical (multi-level) layouts and may mix used
-layouts (fixed and dynamic). Describing that in DT is done by specifying
-"compatible" for DT-represented partition plus optionally more
-properties and/or subnodes.
-
-To support such layouts each DT partition has to be checked for
-additional description.
-
-Please note this implementation will work in parallel with support for
-partition type specified for non-DT setups. That already works since
-commit 1a0915be1926 ("mtd: partitions: add support for partition
-parsers").

-Subject: i2c: gpio: Enable working over slow can_sleep GPIOs
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-"Slow" GPIOs (usually those connected over an SPI or an I2C bus) are,
-well, slow in their operation. It is generally a good idea to avoid
-using them for time-critical operation, but sometimes the hardware just
-sucks, and the software has to cope. In addition to that, the I2C bus
-itself does not actually define any strict timing limits; the bus is
-free to go all the way down to DC. The timeouts (and therefore the
-slowest acceptable frequency) are present only in SMBus.
-
-The `can_sleep` is IMHO a wrong concept to use here. My SPI-to-quad-UART
-chip (MAX14830) is connected via a 26MHz SPI bus, and it happily drives
-SCL at 200kHz (5µs pulses) during my benchmarks. That's faster than the
-maximal allowed speed of the traditional I2C.
-
-The previous version of this code did not really block operation over
-slow GPIO pins, anyway. Instead, it just resorted to printing a warning
-with a backtrace each time a GPIO pin was accessed, thereby slowing
-things down even more.
-
-Finally, it's not just me. A similar patch was originally submitted in
-2015 [1].

-Subject: [PATCH] net: bridge: add support for port isolation
-
-This patch adds support for a new port flag - BR_ISOLATED. If it is set
-then isolated ports cannot communicate between each other, but they can
-still communicate with non-isolated ports. The same can be achieved via
-ACLs but they can't scale with large number of ports and also the
-complexity of the rules grows. This feature can be used to achieve
-isolated vlan functionality (similar to pvlan) as well, though currently
-it will be port-wide (for all vlans on the port). The new test in
-should_deliver uses data that is already cache hot and the new boolean
-is used to avoid an additional source port test in should_deliver.

-("netfilter: core: batch nf_unregister_net_hooks synchronize_net calls").
-
-Nothing wrong with it. However, followup patch will delay freeing of hooks

-Subject: [PATCH 04/11] netfilter: core: free hooks with call_rcu
-
-Giuseppe Scrivano says:
- "SELinux, if enabled, registers for each new network namespace 6
- netfilter hooks."
-
-Cost for this is high. With synchronize_net() removed:
- "The net benefit on an SMP machine with two cores is that creating a
- new network namespace takes -40% of the original time."
-
-This patch replaces synchronize_net+kvfree with call_rcu().
-We store rcu_head at the tail of a structure that has no fixed layout,
-i.e. we cannot use offsetof() to compute the start of the original
-allocation. Thus store this information right after the rcu head.
-
-We could simplify this by just placing the rcu_head at the start
-of struct nf_hook_entries. However, this structure is used in
-packet processing hotpath, so only place what is needed for that
-at the beginning of the struct.

-Subject: [PATCH 05/11] netfilter: reduce size of hook entry point locations
-
-struct net contains:
-
-struct nf_hook_entries __rcu *hooks[NFPROTO_NUMPROTO][NF_MAX_HOOKS];
-
-which store the hook entry point locations for the various protocol
-families and the hooks.
-
-Using array results in compact c code when doing accesses, i.e.
- x = rcu_dereference(net->nf.hooks[pf][hook]);
-
-but its also wasting a lot of memory, as most families are
-not used.
-
-So split the array into those families that are used, which
-are only 5 (instead of 13). In most cases, the 'pf' argument is
-constant, i.e. gcc removes switch statement.
-
-struct net before:
- /* size: 5184, cachelines: 81, members: 46 */
-after:
- /* size: 4672, cachelines: 73, members: 46 */

-Instead of calling this function from the family specific variant, this
-reduces the code size in the fast path for the netdev, bridge and inet
-families. After this change, we must call nft_set_pktinfo() upfront from
-the chain hook indirection.

-Subject: [PATCH] netfilter: core: only allow one nat hook per hook point
-
-The netfilter NAT core cannot deal with more than one NAT hook per hook
-location (prerouting, input ...), because the NAT hooks install a NAT null
-binding in case the iptables nat table (iptable_nat hooks) or the
-corresponding nftables chain (nft nat hooks) doesn't specify a nat
-transformation.
-
-Null bindings are needed to detect port collsisions between NAT-ed and
-non-NAT-ed connections.
-
-This causes nftables NAT rules to not work when iptable_nat module is
-loaded, and vice versa because nat binding has already been attached
-when the second nat hook is consulted.
-
-The netfilter core is not really the correct location to handle this
-(hooks are just hooks, the core has no notion of what kinds of side
- effects a hook implements), but its the only place where we can check
-for conflicts between both iptables hooks and nftables hooks without
-adding dependencies.
-
-So add nat annotation to hook_ops to describe those hooks that will
-add NAT bindings and then make core reject if such a hook already exists.
-The annotation fills a padding hole, in case further restrictions appar
-we might change this to a 'u8 type' instead of bool.
-
-iptables error if nft nat hook active:
-iptables -t nat -A POSTROUTING -j MASQUERADE
-iptables v1.4.21: can't initialize iptables table `nat': File exists
-Perhaps iptables or your kernel needs to be upgraded.
-
-nftables error if iptables nat table present:
-nft -f /etc/nftables/ipv4-nat
-/usr/etc/nftables/ipv4-nat:3:1-2: Error: Could not process rule: File exists
-table nat {

-Subject: [PATCH] netfilter: move checksum indirection to struct nf_ipv6_ops
-
-We cannot make a direct call to nf_ip6_checksum() because that would
-result in autoloading the 'ipv6' module because of symbol dependencies.
-Therefore, define checksum indirection in nf_ipv6_ops where this really
-belongs to.
-
-For IPv4, we can indeed make a direct function call, which is faster,
-given IPv4 is built-in in the networking code by default. Still,
-CONFIG_INET=n and CONFIG_NETFILTER=y is possible, so define empty inline
-stub for IPv4 in such case.

-Subject: [PATCH] netfilter: move route indirection to struct nf_ipv6_ops
-
-We cannot make a direct call to nf_ip6_route() because that would result
-in autoloading the 'ipv6' module because of symbol dependencies.
-Therefore, define route indirection in nf_ipv6_ops where this really
-belongs to.
-
-For IPv4, we can indeed make a direct function call, which is faster,
-given IPv4 is built-in in the networking code by default. Still,
-CONFIG_INET=n and CONFIG_NETFILTER=y is possible, so define empty inline
-stub for IPv4 in such case.

-Subject: [PATCH] netfilter: remove defensive check on malformed packets from
- raw sockets
-
-Users cannot forge malformed IPv4/IPv6 headers via raw sockets that they
-can inject into the stack. Specifically, not for IPv4 since 55888dfb6ba7
-("AF_RAW: Augment raw_send_hdrinc to expand skb to fit iphdr->ihl
-(v2)"). IPv6 raw sockets also ensure that packets have a well-formed
-IPv6 header available in the skbuff.
-
-At quick glance, br_netfilter also validates layer 3 headers and it
-drops malformed both IPv4 and IPv6 packets.
-
-Therefore, let's remove this defensive check all over the place.

-Subject: [PATCH] netfilter: nf_conntrack: add IPS_OFFLOAD status bit
-
-This new bit tells us that the conntrack entry is owned by the flow
-table offload infrastructure.
-
- # cat /proc/net/nf_conntrack
- ipv4 2 tcp 6 src=10.141.10.2 dst=147.75.205.195 sport=36392 dport=443 src=147.75.205.195 dst=192.168.2.195 sport=443 dport=36392 [OFFLOAD] mark=0 zone=0 use=2
-
-Note the [OFFLOAD] tag in the listing.
-
-The timer of such conntrack entries look like stopped from userspace.
-In practise, to make sure the conntrack entry does not go away, the
-conntrack timer is periodically set to an arbitrary large value that
-gets refreshed on every iteration from the garbage collector, so it
-never expires- and they display no internal state in the case of TCP
-flows. This allows us to save a bitcheck from the packet path via
-nf_ct_is_expired().
-
-Conntrack entries that have been offloaded to the flow table
-infrastructure cannot be deleted/flushed via ctnetlink. The flow table
-infrastructure is also responsible for releasing this conntrack entry.

-Subject: [PATCH] netfilter: nf_tables: add flow table netlink frontend
-
-This patch introduces a netlink control plane to create, delete and dump
-flow tables. Flow tables are identified by name, this name is used from
-rules to refer to an specific flow table. Flow tables use the rhashtable
-class and a generic garbage collector to remove expired entries.
-
-This also adds the infrastructure to add different flow table types, so
-we can add one for each layer 3 protocol family.

-Subject: [PATCH] netfilter: add generic flow table infrastructure
-
-This patch defines the API to interact with flow tables, this allows to
-add, delete and lookup for entries in the flow table. This also adds the
-generic garbage code that removes entries that have expired, ie. no
-traffic has been seen for a while.
-
-Users of the flow table infrastructure can delete entries via
-flow_offload_dead(), which sets the dying bit, this signals the garbage
-collector to release an entry from user context.
-

-Subject: [PATCH] netfilter: flow table support for IPv4
-
-This patch adds the IPv4 flow table type, that implements the datapath
-flow table to forward IPv4 traffic. Rationale is:
-
-1) Look up for the packet in the flow table, from the ingress hook.
-2) If there's a hit, decrement ttl and pass it on to the neighbour layer
- for transmission.
-3) If there's a miss, packet is passed up to the classic forwarding
- path.
-
-This patch also supports layer 3 source and destination NAT.

-Subject: [PATCH] netfilter: flow table support for IPv6
-
-This patch adds the IPv6 flow table type, that implements the datapath
-flow table to forward IPv6 traffic.
-
-This patch exports ip6_dst_mtu_forward() that is required to check for
-mtu to pass up packets that need PMTUD handling to the classic
-forwarding path.

-Subject: [PATCH] netfilter: nf_tables: flow offload expression
-
-Add new instruction for the nf_tables VM that allows us to specify what
-flows are offloaded into a given flow table via name. This new
-instruction creates the flow entry and adds it to the flow table.
-
-Only established flows, ie. we have seen traffic in both directions, are
-added to the flow table. You can still decide to offload entries at a
-later stage via packet counting or checking the ct status in case you
-want to offload assured conntracks.
-
-This new extension depends on the conntrack subsystem.

- nft_af_info
-
-We already validate the hook through bitmask, so this check is
-superfluous. When removing this, this patch is also fixing a bug in the
-new flowtable codebase, since ctx->afi points to the table family
-instead of the netdev family which is where the flowtable is really
-hooked in.

-
-Place all existing user defined tables in struct net *, instead of
-having one list per family. This saves us from one level of indentation
-in netlink dump functions.
-
-Place pointer to struct nft_af_info in struct nft_table temporarily, as
-we still need this to put back reference module reference counter on
-table removal.

-Subject: [PATCH] netfilter: nf_tables: get rid of pernet families
-
-Now that we have a single table list for each netns, we can get rid of
-one pointer per family and the global afinfo list, thus, shrinking
-struct netns for nftables that now becomes 64 bytes smaller.
-
-And call __nft_release_afinfo() from __net_exit path accordingly to
-release netnamespace objects on removal.

-Subject: [PATCH] netfilter: nft_flow_offload: wait for garbage collector
- to run after cleanup
-
-If netdevice goes down, then flowtable entries are scheduled to be
-removed. Wait for garbage collector to have a chance to run so it can
-delete them from the hashtable.
-
-The flush call might sleep, so hold the nfnl mutex from
-nft_flow_table_iterate() instead of rcu read side lock. The use of the
-nfnl mutex is also implicitly fixing races between updates via nfnetlink
-and netdevice event.

-Subject: [PATCH] netfilter: nf_tables: fix flowtable free
-
-Every flow_offload entry is added into the table twice. Because of this,
-rhashtable_free_and_destroy can't be used, since it would call kfree for
-each flow_offload object twice.
-
-This patch adds a call to nf_flow_table_iterate_cleanup() to schedule
-removal of entries, then there is an explicitly invocation of the
-garbage collector to clean up resources.

-Subject: [PATCH] netfilter: nf_flow_offload: fix use-after-free and a resource
- leak
-
-flow_offload_del frees the flow, so all associated resource must be
-freed before.
-
-Since the ct entry in struct flow_offload_entry was allocated by
-flow_offload_alloc, it should be freed by flow_offload_free to take care
-of the error handling path when flow_offload_add fails.
-
-While at it, make flow_offload_del static, since it should never be
-called directly, only from the gc step

-Subject: [PATCH] netfilter: flowtable infrastructure depends on
- NETFILTER_INGRESS
-
-config NF_FLOW_TABLE depends on NETFILTER_INGRESS. If users forget to
-enable this toggle, flowtable registration fails with EOPNOTSUPP.
-
-Moreover, turn 'select NF_FLOW_TABLE' in every flowtable family flavour
-into dependency instead, otherwise this new dependency on
-NETFILTER_INGRESS causes a warning. This also allows us to remove the
-explicit dependency between family flowtables <-> NF_TABLES and
-NF_CONNTRACK, given they depend on the NF_FLOW_TABLE core that already
-expresses the general dependencies for this new infrastructure.
-
-Moreover, NF_FLOW_TABLE_INET depends on NF_FLOW_TABLE_IPV4 and
-NF_FLOWTABLE_IPV6, which already depends on NF_FLOW_TABLE. So we can get
-rid of direct dependency with NF_FLOW_TABLE.
-
-In general, let's avoid 'select', it just makes things more complicated.

- nf_flow_table
-
-Allows some minor code sharing with the ipv6 hook code and is also
-useful as preparation for adding iptables support for offload

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Make sure only to copy any actual data rather than the whole buffer,
-when releasing the temporary buffer used for unaligned non-isochronous
-transfers.
-
-Taken directly from commit 0efd937e27d5e ("USB: ehci-tegra: fix inefficient
-copy of unaligned buffers")
-
-Tested with Lantiq xRX200 (MIPS) and RPi Model B Rev 2 (ARM)

+Subject: [PATCH 1/3] MIPS: Compile post DMA flush only when needed
-If no post-DMA flush is required, and the platform does not provide
-plat_unmap_dma_mem(), there is no need to include unmap or sync_for_cpu
-ops.
+dma_sync_phys() is only called for some CPUs when a mapping is removed.
+Add ARCH_HAS_SYNC_DMA_FOR_CPU only for the CPUs listed in
+cpu_needs_post_dma_flush() which need this extra call and do not compile
+this code in for other CPUs. We need this for R10000, R12000, BMIPS5000
+CPUs and CPUs supporting MAAR which was introduced in MIPS32r5.
-With this patch they are compiled out to improve icache footprint
-on devices that handle lots of DMA traffic (especially network routers).
+This will hopefully improve the performance of the not affected devices.

-Subject: [PATCH] mtd: m25p80: allow fallback from spi_flash_read to regular
- SPI transfer
-
-Some flash controllers, e.g. on the ath79 platform can support a fast
-flash read via memory mapping, but only if the flash chip is in
-3-byte address mode.
-
-Since spi_flash_read_supported does not have access to the same data as
-spi_flash_read, the driver can't detect an unsupported call until m25p80
-has decided to use spi_flash_read.
-
-Allow the driver to indicate a fallback to a regular SPI transfer by
-returning -EOPNOTSUPP
-

-From: Daniel Golle <daniel@makrotopia.org>
-Date: Mon, 4 Jun 2018 14:51:29 +0200
-Subject: [PATCH] tty: serial: exar: generalize rs485 setup
-To: linux-serial@vger.kernel.org,
- Greg Kroah-Hartman <gregkh@linuxfoundation.org>
-Cc: Linus Walleij <linus.walleij@linaro.org>,
- Jan Kiszka <jan.kiszka@siemens.com>
-
-Move the non-board-specific part of the RS485 initialization
-from iot2040_rs485_config function to a new generic function
-used also for other boards.
-This allows using PCIe boards which are hard-wired to RS485
-or have jumpers for their configurations.
