-Subject: netfilter: conntrack: cache route for forwarded connections
-
-... to avoid per-packet FIB lookup if possible.
-
-The cached dst is re-used provided the input interface
-is the same as that of the previous packet in the same direction.
-
-If not, the cached dst is invalidated.
-
-For ipv6 we also need to store sernum, else dst_check doesn't work,
-pointed out by Eric Dumazet.
-
-This should speed up forwarding when conntrack is already in use
-anyway, especially when using reverse path filtering -- active RPF
-enforces two FIB lookups for each packet.
-
-Before the routing cache removal this didn't matter since RPF was performed
-only when route cache didn't yield a result; but without route cache it
-comes at higher price.
-
-Julian Anastasov suggested to add NETDEV_UNREGISTER handler to
-avoid holding on to dsts of 'frozen' conntracks.

-Subject: [PATCH] bgmac: reset all 4 GMAC cores on init
-
-On a BCM4709 based device, I found that GMAC cores may be enabled at
-probe time, but only become usable after a full reset.
-Disable cores before re-enabling them to ensure that they are properly
-reset.

-Subject: [PATCH] MIPS: fix cache flushing for highmem pages
-
-Most cache flush ops were no-op for highmem pages. This led to nasty
-segfaults and (in the case of page_address(page) == NULL) kernel
-crashes.
-
-Fix this by always flushing highmem pages using kmap/kunmap_atomic
-around the actual cache flush. This might be a bit inefficient, but at
-least it's stable.

-This patch adds an ignore_oc flag which can be set by EHCI controller

-Subject: bridge: allow receiption on disabled port
-
-When an ethernet device is enslaved to a bridge, and the bridge STP
-detects loss of carrier (or operational state down), then normally
-packet receiption is blocked.
-
-This breaks control applications like WPA which maybe expecting to
-receive packets to negotiate to bring link up. The bridge needs to
-block forwarding packets from these disabled ports, but there is no
-hard requirement to not allow local packet delivery.

-Subject: [PATCH] MIPS: partially inline dma ops
-
-Several DMA ops are no-op on many platforms, and the indirection through
-the mips_dma_map_ops function table is causing the compiler to emit
-unnecessary code.
-
-Inlining visibly improves network performance in my tests (on a 24Kc
-based system), and also slightly reduces code size of a few drivers.

-This moves the linux,part-probe device tree parsing code from
-physmap_of.c to mtdpart.c. Now all drivers can use this feature by just
-providing a reference to their device tree node in struct
-mtd_part_parser_data.

-
-This commit is breaking read access on at least s25fl064k, but also

- definition
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-So far struct spi_nor was using just a pointer to struct mtd_info so it
-wasn't needed to have it fully defined there. After recent change we
-embed whole struct so we need to include a proper header.
-
-Fixes: 1976367173a4 ("mtd: spi-nor: embed struct mtd_info within struct spi_nor")

- only
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-We allowed using bcm47xxpart on BCM5301X arch with commit:
-9e3afa5f5c7 ("mtd: bcm47xxpart: allow enabling on ARCH_BCM_5301X")
-
-BCM5301X devices may contain some partitions in higher memory, e.g.
-Netgear R8000 has board_data at 0x2600000. To detect them we should
-use size limit on MIPS only.

-Subject: [PATCH 1/3] uapi/kernel.h: glibc specific inclusion of sysinfo.h
-
-including sysinfo.h from kernel.h makes no sense whatsoever,
-but removing it breaks glibc's userspace header,
-which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
-this seems to be a historical mistake.
-on musl, including any header that uses kernel.h directly or indirectly
-plus sys/sysinfo.h will produce a compile error due to redefinition of
-struct sysinfo from sys/sysinfo.h.
-so for now, only include it on glibc or when including from kernel
-in order not to break their headers.

-
-Musl provides the same structs as glibc, but does not provide a define to
-allow its detection. Since the absence of __GLIBC__ also can mean that it
-is included from the kernel, change the __GLIBC__ detection to
-!__KERNEL__, which should always be true when included from userspace.

-Subject: [PATCH 3/7] skb_reduce_truesize: helper function for shrinking skbs
- whenever needed
-
-On embedded devices in particular, large queues of small packets from the rx
-path with a large truesize can exist. Reducing their size can reduce
-memory pressure. skb_reduce_truesize is a helper function for doing this,
-when needed.

-Subject: [PATCH] Add support for MAP-E FMRs (mesh mode)
-
-MAP-E FMRs (draft-ietf-softwire-map-10) are rules for IPv4-communication
-between MAP CEs (mesh mode) without the need to forward such data to a
-border relay. This is similar to how 6rd works but for IPv4 over IPv6.

-Subject: [PATCH 1/2] ipv6: allow rejecting with "source address failed policy"
-
-RFC6204 L-14 requires rejecting traffic from invalid addresses with
-ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
-egress policy) on the LAN side, so add an appropriate rule for that.

-Subject: NET: skip GRO for foreign MAC addresses
-
-For network drivers using napi_gro_receive, packets are run through GRO,
-even when the destination MAC address does not match, and they're supposed
-to be delivered to another host behind a different bridge port.
-
-This can be very expensive, because for drivers without TSO or scatter-
-gather, this can only be undone by copying the skb and checksumming it
-again.
-
-To be able to track foreign MAC addresses in an inexpensive way, create
-a mask of changed bits in MAC addresses of upper devices. This allows
-handling VLANs and bridge devices with different addresses (as long as
-they are not too different).

- 8139cp: Fix GSO MSS handling
-
- When fixing the TSO support I noticed we just mask ->gso_size with the
- MSSMask value and don't care about the consequences.
-
- Provide a .ndo_features_check() method which drops the NETIF_F_TSO
- feature for any skb which would exceed the maximum, and thus forces it
- to be segmented by software.
-
- Then we can stop the masking in cp_start_xmit(), and just WARN if the
- maximum is exceeded, which should now never happen.
-
- Finally, Francois Romieu noticed that we didn't even have the right
- value for MSSMask anyway; it should be 0x7ff (11 bits) not 0xfff.

- I fixed TSO. Hardware checksum and scatter/gather also appear to be
- working correctly both on real hardware and in QEMU's emulation.
-
- Let's enable them by default and see if anyone screams...

-Subject: [PATCH] igb: Fix Null-pointer dereference in igb_reset_q_vector
-
-When igb_set_interrupt_capability() calls
-igb_reset_interrupt_capability() (e.g., because CONFIG_PCI_MSI is unset),
-num_q_vectors has been set but no vector has yet been allocated.
-
-igb_reset_interrupt_capability() will then call igb_reset_q_vector,
-which assumes that the vector is allocated. As this is not the case, we
-are accessing a NULL-pointer.
-
-This patch fixes it by checking that q_vector is indeed different from
-NULL.

-Subject: [PATCH] libata: add ledtrig support
-To: linux-ide@vger.kernel.org,
- Tejun Heo <tj@kernel.org>
-
-This adds a LED trigger for each ATA port indicating disk activity.
-
-As this is needed only on specific platforms (NAS SoCs and such),
-these platforms should define ARCH_WANTS_LIBATA_LEDS if there
-are boards with LED(s) intended to indicate ATA disk activity and
-need the OS to take care of that.
-In that way, if not selected, LED trigger support not will be
-included in libata-core and both, codepaths and structures remain
-untouched.
-
-Signed-off-by: Daniel Golle <daniel@makrotopia.org>

-+GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
-+================================================================
-+
-+The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
-+MMC or SD card on GPIO pins.
-+
-+Two interfaces for registering a new MMC/SD card device are provided:
-+A static platform-device based mechanism and a dynamic configfs based interface.
-+
-+
-+Registering devices via platform-device
-+=======================================
-+
-+The platform-device interface is used for registering MMC/SD devices that are
-+part of the hardware platform. This is most useful only for embedded machines
-+with MMC/SD devices statically connected to the platform GPIO bus.
-+
-+The data structures are declared in <linux/mmc/gpiommc.h>.
-+
-+To register a new device, define an instance of struct gpiommc_platform_data.
-+This structure holds any information about how the device is hooked up to the
-+GPIO pins and what hardware modes the device supports. See the docbook-style
-+documentation in the header file for more information on the struct fields.
-+
-+Then allocate a new instance of a platform device by doing:
-+
-+ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
-+
-+This will allocate the platform device data structures and hook it up to the
-+gpiommc driver.
-+Then add the gpiommc_platform_data to the platform device.
-+
-+ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
-+
-+You may free the local instance of struct gpiommc_platform_data now. (So the
-+struct may be allocated on the stack, too).
-+Now simply register the platform device.
-+
-+ err = platform_device_add(pdev);
-+
-+Done. The gpiommc probe routine will be invoked now and you should see a kernel
-+log message for the added device.
-+
-+
-+Registering devices via configfs
-+================================
-+
-+MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
-+selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
-+hardware are a common situation.
-+So we provide a dynamic interface to conveniently handle adding and removing
-+devices from userspace, without the need to recompile the kernel.
-+
-+The "gpiommc" subdirectory at the configfs mountpoint is used for handling
-+the dynamic configuration.
-+
-+To create a new device, it must first be allocated with mkdir.
-+The following command will allocate a device named "my_mmc":
-+ mkdir /config/gpiommc/my_mmc
-+
-+There are several configuration files available in the new
-+/config/gpiommc/my_mmc/ directory:
-+
-+gpio_data_in = The SPI data-IN GPIO pin number.
-+gpio_data_out = The SPI data-OUT GPIO pin number.
-+gpio_clock = The SPI Clock GPIO pin number.
-+gpio_chipselect = The SPI Chipselect GPIO pin number.
-+gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
-+ If 1, Chipselect is active-LOW.
-+spi_mode = The SPI data mode. Can be 0-3.
-+spi_delay = Enable all delays in the lowlevel bitbanging.
-+max_bus_speed = The maximum SPI bus speed. In Hertz.
-+
-+register = Not a configuration parameter.
-+ Used to register the configured card
-+ with the kernel.
-+
-+The device must first get configured and then registered by writing "1" to
-+the "register" file.
-+The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
-+and "gpio_chipselect" are essential and _must_ be configured before writing
-+"1" to the "register" file. The registration will fail, otherwise.
-+
-+The default values for the other parameters are:
-+gpio_chipselect_activelow = 1 (CS active-LOW)
-+spi_mode = 0 (SPI_MODE_0)
-+spi_delay = 1 (enabled)
-+max_bus_speed = 5000000 (5 Mhz)
-+
-+Configuration values can not be changed after registration. To unregister
-+the device, write a "0" to the "register" file. The configuration can be
-+changed again after unregistering.
-+
-+To completely remove the device, simply rmdir the directory
-+(/config/gpiommc/my_mmc in this example).
-+There's no need to first unregister the device before removing it. That will
-+be done automatically.
