sh: push extra copy of r0-r2 for syscall parameters
When invoking syscall handlers on sh32, the saved userspace registers
are at the top of the stack. This seems to have been intentional, as it
is an easy way to pass r0, r1, ... to the handler as parameters 5, 6,
...
It causes problems, however, because the compiler is allowed to generate
code for a function which clobbers that function's own parameters. For
example, gcc generates the following code for clone:
<SyS_clone>:
mov.l
8c020714 <SyS_clone+0xc>,r1 !
8c020540 <do_fork>
mov.l r7,@r15
mov r6,r7
jmp @r1
mov #0,r6
nop
.word 0x0540
.word 0x8c02
The `mov.l r7,@r15` clobbers the saved value of r0 passed from
userspace. For most system calls, this might not be a problem, because
we'll be overwriting r0 with the return value anyway. But in the case
of clone, copy_thread will need the original value of r0 if the
CLONE_SETTLS flag was specified.
The first patch in this series fixes this issue for system calls by
pushing to the stack and extra copy of r0-r2 before invoking the
handler. We discard this copy before restoring the userspace registers,
so it is not a problem if they are clobbered.
Exception handlers also receive the userspace register values in a
similar manner, and may hit the same problem. The second patch removes
the do_fpu_error handler, which looks susceptible to this problem and
which, as far as I can tell, has not been used in some time. The third
patch addresses other exception handlers.
This patch (of 3):
The userspace registers are stored at the top of the stack when the
syscall handler is invoked, which allows r0-r2 to act as parameters 5-7.
Parameters passed on the stack may be clobbered by the syscall handler.
The solution is to push an extra copy of the registers which might be
used as syscall parameters to the stack, so that the authoritative set
of saved register values does not get clobbered.
A few system call handlers are also updated to get the userspace
registers using current_pt_regs() instead of from the stack.

genksyms: fix typeof() handling
Recent increased use of typeof() throughout the tree resulted in a
number of symbols (25 in a typical distro config of ours) not getting a
proper CRC calculated for them anymore, due to the parser in genksyms
not coping with several of these uses (interestingly in the majority of
[if not all] cases the problem is due to the use of typeof() in code
preceding a certain export, not in the declaration/definition of the
exported function/object itself; I wasn't able to find a way to address
this more general parser shortcoming).
The use of parameter_declaration is a little more relaxed than would be
ideal (permitting not just a bare type specification, but also one with
identifier), but since the same code is being passed through an actual
compiler, there's no apparent risk of allowing through any broken code.
Otoh using parameter_declaration instead of the ad hoc
"decl_specifier_seq '*'" / "decl_specifier_seq" pair allows all types to
be handled rather than just plain ones and pointers to plain ones.

Currently, fanotify creates new structure to track the fact that
permission event has been reported to userspace and someone is waiting
for a response to it. As event structures are now completely in the
hands of each notification framework, we can use the event structure for
this tracking instead of allocating a new structure.
Since this makes the event structures for normal events and permission
events even more different and the structures have different lifetime
rules, we split them into two separate structures (where permission
event structure contains the structure for a normal event). This makes
normal events 8 bytes smaller and the code a tad bit cleaner.

bdi: avoid oops on device removal
After commit
839a8e8660b6 ("writeback: replace custom worker pool
implementation with unbound workqueue") when device is removed while we
are writing to it we crash in bdi_writeback_workfn() ->
set_worker_desc() because bdi->dev is NULL.
This can happen because even though bdi_unregister() cancels all pending
flushing work, nothing really prevents new ones from being queued from
balance_dirty_pages() or other places.
Fix the problem by clearing BDI_registered bit in bdi_unregister() and
checking it before scheduling of any flushing work.

backing_dev: fix hung task on sync
bdi_wakeup_thread_delayed() used the mod_delayed_work() function to
schedule work to writeback dirty inodes. The problem with this is that
it can delay work that is scheduled for immediate execution, such as the
work from sync_inodes_sb(). This can happen since mod_delayed_work()
can now steal work from a work_queue. This fixes the problem by using
queue_delayed_work() instead. This is a regression caused by commit
839a8e8660b6 ("writeback: replace custom worker pool implementation with
unbound workqueue").
The reason that this causes a problem is that laptop-mode will change
the delay, dirty_writeback_centisecs, to 60000 (10 minutes) by default.
In the case that bdi_wakeup_thread_delayed() races with
sync_inodes_sb(), sync will be stopped for 10 minutes and trigger a hung
task. Even if dirty_writeback_centisecs is not long enough to cause a
hung task, we still don't want to delay sync for that long.
We fix the problem by using queue_delayed_work() when we want to
schedule writeback sometime in future. This function doesn't change the
timer if it is already armed.
For the same reason, we also change bdi_writeback_workfn() to
immediately queue the work again in the case that the work_list is not
empty. The same problem can happen if the sync work is run on the
rescue worker.

pidns_get()->get_pid_ns() can hit ns == NULL. This task_struct can't
go away, but task_active_pid_ns(task) is NULL if release_task(task)

"This time around, the powerpc merges are going to be a little bit more

This is the main pull request with most of the work for this merge
window. I will describe it a bit more further down.
There is some additional cpuidle driver work, however I haven't
included it in this tree as it depends on some work in tip/timer-core
which Thomas accidentally forgot to put in a topic branch. Since I
didn't want to carry all of that tip timer stuff in powerpc -next, I
setup a separate branch on top of Thomas tree with just that cpuidle
driver in it, and Stephen has been carrying that in next separately
for a while now. I'll send a separate pull request for it.
Additionally, two new pieces in this tree add users for a sysfs API
that Tejun and Greg have been deprecating in drivers-core-next.
Thankfully Greg reverted the patch that removes the old API so this
merge can happen cleanly, but once merged, I will send a patch
adjusting our new code to the new API so that Greg can send you the
removal patch.
Now as for the content of this branch, we have a lot of perf work for
power8 new counters including support for our new "nest" counters
(also called 24x7) under pHyp (not natively yet).
We have new functionality when running under the OPAL firmware
(non-virtualized or KVM host), such as access to the firmware error
logs and service processor dumps, system parameters and sensors, along
with a hwmon driver for the latter.
There's also a bunch of bug fixes accross the board, some LE fixes,
and a nice set of selftests for validating our various types of copy
loops.
On the Freescale side, we see mostly new chip/board revisions, some
clock updates, better support for machine checks and debug exceptions,

This is not the end of the vdso cleanups. Stefani and Andy have
agreed to continue work for the next kernel cycle; in fact Andy has
already produced another set of cleanups that came too late for this

An incidental, but arguably important, change is that this ensures

Pull sound updates from Takashi Iwai:
"There have been lots of changes in ALSA core, HD-audio and ASoC, also
most of PCI drivers touched by conversions of printks. All these
resulted in a high volume and wide ranged patch sets in this release.
Many changes are fairly trivial, but also lots of nice cleanups and
refactors. There are a few new drivers, most notably, the Intel
Haswell and Baytrail ASoC driver.
Core changes:
- A bit modernization; embed the device struct into snd_card struct,
so that it may be referred from the beginning. A new
snd_card_new() function is introduced for that, and all drivers
have been converted.
- Simplification in the device management code in ALSA core; now
managed by a simple priority list instead
- Converted many kernel messages to use the standard dev_err() & co;
this would be the pretty visible difference, especially for
HD-audio.
HD-audio:
- Conexant codecs use the auto-parser as default now; the old static
code still remains in case of regressions. Some old quirks have
been rewritten with the fixups for auto-parser.
- C-Media codecs also use the auto-parser as default now, too.
- A device struct is assigned to each HD-audio codec, and the
formerly hwdep attributes are accessible over the codec sysfs, too.
hwdep attributes still remain for compatibility.
- Split the PCI-specific stuff for HD-audio controller into a
separate module, ane make a helper module for the generic
controller driver. This is a preliminary change for supporting
Tegra HDMI controller in near future, which slipped from 3.15
merge.
- Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED
fix for HP laptops, more ASUS subwoofer quirks, yet more Dell
laptop headset quirks
- Make the HD-audio codec response a bit more robust
- A few improvements on Realtek ALC282 / 283 about the pop noises
- A couple of Intel HDMI fixes
ASoC:
- Lots of cleanups for enumerations; refactored lots of error prone
original codes to use more modern APIs
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle
- Provide both manually and transparently locked DAPM APIs rather
than a mix of the two fixing some concurrency issues
- Start converting CODEC drivers to use separate bus interface
drivers rather than having them all in one file helping avoid
dependency issues
- DPCM support for Intel Haswell and Bay Trail platforms, lots of
fixes
- Lots of work on improvements for simple-card, DaVinci and the
Renesas rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of
the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8
- Fixes for the simple-card DAI format DT mess
- DT support for a couple more devices.
- Use of the tdm_slot mapping in a few drivers
Others:
- Support of reset_resume callback for improved S4 in USB-audio
driver; the device with boot quirks have been little tested, which
we need to watch out in this development cycle
- Add PM support for ICE1712 driver (finally!); it's still pretty
partial support, only for M-Audio devices"

of what the requirements are of actually freeing a skb in hard irq
context.

====================
this is a pull request of 16 patches for the 3.15 release cycle.
Bjorn Van Tilt contributes a patch which fixes a memory leak in usb_8dev's
usb_8dev_start_xmit()s error path. A patch by Robert Schwebel fixes a typo in
the can documentation. The remaining patches all target the c_can driver. Two
of them are by me; they add a missing netif_napi_del() and return value
checking. Thomas Gleixner contributes 12 patches, which address several
shortcomings in the driver like hardware initialisation, concurrency, message
ordering and poor performance.

qlcnic: Fix build failure due to undefined reference to `vxlan_get_rx_port'
Commit
2b3d7b758c687("qlcnic: Add VXLAN Rx offload support") uses
vxlan_get_rx_port() which caused build failure when VXLAN=m.
This patch fixes the build failure by adding dependency on VXLAN
in Kconfig of qlcnic module and use vxlan_get_rx_port() and support
code accordingly.

net: ptp: move PTP classifier in its own file
This commit fixes a build error reported by Fengguang, that is
triggered when CONFIG_NETWORK_PHY_TIMESTAMPING is not set:
ERROR: "ptp_classify_raw" [drivers/net/ethernet/oki-semi/pch_gbe/pch_gbe.ko] undefined!
The fix is to introduce its own file for the PTP BPF classifier,
so that PTP_1588_CLOCK and/or NETWORK_PHY_TIMESTAMPING can select
it independently from each other. IXP4xx driver on ARM needs to
select it as well since it does not seem to select PTP_1588_CLOCK
or similar that would pull it in automatically.
This also allows for hiding all of the internals of the BPF PTP
program inside that file, and only exporting relevant API bits
to drivers.
This patch also adds a kdoc documentation of ptp_classify_raw()
API to make it clear that it can return PTP_CLASS_* defines. Also,
the BPF program has been translated into bpf_asm code, so that it
can be more easily read and altered (extensively documented in [1]).
In the kernel tree under tools/net/ we have bpf_asm and bpf_dbg
tools, so the commented program can simply be translated via
`./bpf_asm -c prog` where prog is a file that contains the
commented code. This makes it easily readable/verifiable and when
there's a need to change something, jump offsets etc do not need
to be replaced manually which can be very error prone. Instead,
a newly translated version via bpf_asm can simply replace the old
code. I have checked opcode diffs before/after and it's the very
same filter.

Call efx_set_channels() before efx->type->dimension_resources()
When using the "separate_tx_channels=1" module parameter, the TX queues are
initially numbered starting from the first TX-only channel number (after all the
RX-only channels). efx_set_channels() renumbers the queues so that they are
indexed from zero.
On EF10, the TX queues need to be relabelled in this way before calling the

xen-netback: disable rogue vif in kthread context
When netback discovers frontend is sending malformed packet it will
disables the interface which serves that frontend.
However disabling a network interface involving taking a mutex which
cannot be done in softirq context, so we need to defer this process to
kthread context.
This patch does the following:
1. introduce a flag to indicate the interface is disabled.
2. check that flag in TX path, don't do any work if it's true.
3. check that flag in RX path, turn off that interface if it's true.
The reason to disable it in RX path is because RX uses kthread. After
this change the behavior of netback is still consistent -- it won't do
any TX work for a rogue frontend, and the interface will be eventually
turned off.
Also change a "continue" to "break" after xenvif_fatal_tx_err, as it
doesn't make sense to continue processing packets if frontend is rogue.
This is a fix for XSA-90.

All 802.15.4 PHY devices with drivers in tree can support only one WPAN
at any given time, yet the stack allows arbitrarily many WPAN devices to
be created and up at the same time. This cannot work with what the
hardware provides, and in the current implementation, provides an easy
DoS vector to any process on the system that may call socket() and
sendmsg().

Merge tag 'pm+acpi-3.15-rc1' of git://git./linux/kernel/git/rafael/linux-pm
Pull ACPI and power management updates from Rafael Wysocki:
"The majority of this material spent some time in linux-next, some of
it even several weeks. There are a few relatively fresh commits in
it, but they are mostly fixes and simple cleanups.
ACPI took the lead this time, both in terms of the number of commits
and the number of modified lines of code, cpufreq follows and there
are a few changes in the PM core and in cpuidle too.
A new feature that already got some LWN.net's attention is the device
PM QoS extension allowing latency tolerance requirements to be
propagated from leaf devices to their ancestors with hardware
interfaces for specifying latency tolerance. That should help systems
with hardware-driven power management to avoid going too far with it
in cases when there are latency tolerance constraints.
There also are some significant changes in the ACPI core related to
the way in which hotplug notifications are handled. They affect PCI
hotplug (ACPIPHP) and the ACPI dock station code too. The bottom line
is that all those notification now go through the root notify handler
and are propagated to the interested subsystems by means of callbacks
instead of having to install a notify handler for each device object
that we can potentially get hotplug notifications for.
In addition to that ACPICA will now advertise "Windows 2013"
compatibility for _OSI, because some systems out there don't work
correctly if that is not done (some of them don't even boot).
On the system suspend side of things, all of the device suspend and
resume callbacks, except for ->prepare() and ->complete(), are now
going to be executed asynchronously as that turns out to speed up
system suspend and resume on some platforms quite significantly and we
have a few more optimizations in that area.
Apart from that, there are some new device IDs and fixes and cleanups
all over. In particular, the system suspend and resume handling by
cpufreq should be improved and the cpuidle menu governor should be a
bit more robust now.
Specifics:
- Device PM QoS support for latency tolerance constraints on systems
with hardware interfaces allowing such constraints to be specified.
That is necessary to prevent hardware-driven power management from
becoming overly aggressive on some systems and to prevent power
management features leading to excessive latencies from being used
in some cases.
- Consolidation of the handling of ACPI hotplug notifications for
device objects. This causes all device hotplug notifications to go
through the root notify handler (that was executed for all of them
anyway before) that propagates them to individual subsystems, if
necessary, by executing callbacks provided by those subsystems
(those callbacks are associated with struct acpi_device objects
during device enumeration). As a result, the code in question
becomes both smaller in size and more straightforward and all of
those changes should not affect users.
- ACPICA update, including fixes related to the handling of _PRT in
cases when it is broken and the addition of "Windows 2013" to the
list of supported "features" for _OSI (which is necessary to
support systems that work incorrectly or don't even boot without
it). Changes from Bob Moore and Lv Zheng.
- Consolidation of ACPI _OST handling from Jiang Liu.
- ACPI battery and AC fixes allowing unusual system configurations to
be handled by that code from Alexander Mezin.
- New device IDs for the ACPI LPSS driver from Chiau Ee Chew.
- ACPI fan and thermal optimizations related to system suspend and
resume from Aaron Lu.
- Cleanups related to ACPI video from Jean Delvare.
- Assorted ACPI fixes and cleanups from Al Stone, Hanjun Guo, Lan
Tianyu, Paul Bolle, Tomasz Nowicki.
- Intel RAPL (Running Average Power Limits) driver cleanups from
Jacob Pan.

- cpufreq fixes related to system suspend/resume handling from Viresh

- cpufreq core fixes and cleanups from Viresh Kumar, Stratos

- cpufreq drivers updates from Viresh Kumar, Zhuoyu Zhang, Rob

- cpuidle fixes related to the menu governor from Tuukka Tikkanen.
- cpuidle fix related to coupled CPUs handling from Paul Burton.
- Asynchronous execution of all device suspend and resume callbacks,
except for ->prepare and ->complete, during system suspend and
resume from Chuansheng Liu.
- Delayed resuming of runtime-suspended devices during system suspend
for the PCI bus type and ACPI PM domain.
- New set of PM helper routines to allow device runtime PM callbacks
to be used during system suspend and resume more easily from Ulf
Hansson.
- Assorted fixes and cleanups in the PM core from Geert Uytterhoeven,
Prabhakar Lad, Philipp Zabel, Rashika Kheria, Sebastian Capella.

netlink: don't compare the nul-termination in nla_strcmp
nla_strcmp compares the string length plus one, so it's implicitly
including the nul-termination in the comparison.
int nla_strcmp(const struct nlattr *nla, const char *str)
{
int len = strlen(str) + 1;
...
d = memcmp(nla_data(nla), str, len);
However, if NLA_STRING is used, userspace can send us a string without
the nul-termination. This is a problem since the string
comparison will not match as the last byte may be not the
nul-termination.
Fix this by skipping the comparison of the nul-termination if the
attribute data is nul-terminated. Suggested by Thomas Graf.

"The irq department proudly presents:
- Another tree wide sweep of irq infrastructure abuse. Clear winner
of the trainwreck engineering contest was:
#include "../../../kernel/irq/settings.h"
- Tree wide update of irq_set_affinity() callbacks which miss a cpu
online check when picking a single cpu out of the affinity mask.
- Tree wide consolidation of interrupt statistics.
- Updates to the threaded interrupt infrastructure to allow explicit
wakeup of the interrupt thread and a variant of synchronize_irq()
which synchronizes only the hard interrupt handler. Both are
needed to replace the homebrewn thread handling in the mmc/sdhci
code.
- New irq chip callbacks to allow proper support for GPIO based irqs.
The GPIO based interrupts need to request/release GPIO resources
from request/free_irq.
- A few new ARM interrupt chips. No revolutionary new hardware, just
differently wreckaged variations of the scheme.
- Small improvments, cleanups and updates all over the place"
