Pull spi updates from Mark Brown:
"A respun version of the merges for the pull request previously sent
with a few additional fixes. The last two merges were fixed up by
hand since the branches have moved on and currently have the prior
merge in them.
Quite a busy release for the SPI subsystem, mostly in cleanups big and
small scattered through the stack rather than anything else:
- New driver for the Broadcom BC63xx HSSPI controller
- Fix duplicate device registration for ACPI
- Conversion of s3c64xx to DMAEngine (this pulls in platform and DMA
changes upon which the transiton depends)
- Some small optimisations to reduce the amount of time we hold locks
in the datapath, eliminate some redundant checks and the size of a
spi_transfer
- Lots of fixes, cleanups and general enhancements to drivers,
especially the rspi and Atmel drivers"

"The work to convert the kernel to use kuid_t and kgid_t has been

The first patch on this branch just removes the scaffolding, ensuring
we will always get compile errors if people accidentally try the

overlooked and unused chunk of mips code that that fails to build
after the first patch.
The code hasn't been in linux-next for long (as I was out of it and
could not sheppared the cold properly) but the patch has been around
for a long time just waiting for the day when I had finished the
uid/gid conversions. Putting the code in linux-next did find the
compile failure on mips so I took the time to get that fix reviewed
and included. Beyond that I am not too worried about errors because
all these two patches do is delete a modest amount of code"

When khungtaskd detects hung tasks, it prints out
backtraces from a number of those tasks.
Limiting the number of backtraces being printed
out can result in the user not seeing the information
necessary to debug the issue. The hung_task_warnings
sysctl controls this feature.
This patch makes it possible for hung_task_warnings
to accept a special value to print an unlimited
number of backtraces when khungtaskd detects hung
tasks.
The special value is -1. To use this value it is
necessary to change types from ulong to int.

Similarly to other Apple products, MBA 1,1 needs a specific quirk.
Pin 0x18 must be set to VREF_50 to have sound output. This was no
longer done since commit 1a97b7f, resulting in a mute built-in speaker.
This patch corrects the regression by creating a fixup for the MBA 1,1.

put_files_struct() and close_files() do rcu_read_lock() to make
rcu_dereference_check_fdtable() happy.
This looks a bit ugly, files_fdtable() just reads the pointer,
we can simply use rcu_dereference_raw() to avoid the warning.
The patch also changes close_files() to return fdt, this avoids
another rcu_read_lock()/files_fdtable() in put_files_struct().
I think close_files() needs more cleanups:
- we do not need xchg() exactly because we are the last
user of this files_struct
- "if (file)" should be turned into WARN_ON(!file)

rcu_my_thread_group_empty()
rcu_dereference_check_fdtable() looks very wrong,
1. rcu_my_thread_group_empty() was added by 844b9a8707f1 "vfs: fix
RCU-lockdep false positive due to /proc" but it doesn't really
fix the problem. A CLONE_THREAD (without CLONE_FILES) task can
hit the same race with get_files_struct().
And otoh rcu_my_thread_group_empty() can suppress the correct
warning if the caller is the CLONE_FILES (without CLONE_THREAD)
task.
2. files->count == 1 check is not really right too. Even if this
files_struct is not shared it is not safe to access it lockless
unless the caller is the owner.
Otoh, this check is sub-optimal. files->count == 0 always means
it is safe to use it lockless even if files != current->files,
but put_files_struct() has to take rcu_read_lock(). See the next
patch.
This patch removes the buggy checks and turns fcheck_files() into
__fcheck_files() which uses rcu_dereference_raw(), the "unshared"
callers, fget_light() and fget_raw_light(), can use it to avoid
the warning from RCU-lockdep.
fcheck_files() is trivially reimplemented as rcu_lockdep_assert()
plus __fcheck_files().

Fix UV call into kgdb to depend only on whether KGDB is defined
and not both KGDB and KDB. This allows the power nmi command to
use the gdb remote connection if enabled. Note new action of
'kgdb' needs to be set as well to indicate user wants to wait
for gdb to be connected. If it's set to 'kdb' then an error
message is displayed if KDB is not configured.
Also note that if both KGDB and KDB are enabled, then the action
of 'kgdb' or 'kdb' has no affect on which is used. See the KGDB
documentation for further information.

This patch addresses a bug where connection reset would hang

So now make percpu_ida_alloc() check for signal_pending_state() for
making interruptible sleep optional, and convert iscsit_allocate_cmd()
to set TASK_INTERRUPTIBLE for GFP_KERNEL, or TASK_RUNNING for
GFP_ATOMIC.

Pull thermal management updates from Zhang Rui:
"This time, the biggest change is the work of representing hardware
thermal properties in device tree infrastructure.
This work includes the introduction of a device tree bindings for
describing the hardware thermal behavior and limits, and also a parser
to read and interpret the data, and build thermal zones and thermal
binding parameters. It also contains three examples on how to use the
new representation on sensor devices, using three different drivers to
accomplish it. One driver is in thermal subsystem, the TI SoC
thermal, and the other two drivers are in hwmon subsystem.
Actually, this would be the first step of the complete work because we
still need to check other potential drivers to be converted and then
validate the proposed API. But the reason why I include it in this
pull request is that, first, this change does not hurt any others
without using this approach, second, the principle and concept of this
change would not break after converting the remaining drivers. BTW,
as you can see, there are several points in this change that do not
belong to thermal subsystem. Because it has been suggested by Guenter
R that in such cases, it is recommended to send the complete series
via one single subsystem.
Specifics:
- representing hardware thermal properties in device tree
infrastructure
- fix a regression that the imx thermal driver breaks system suspend.
- introduce ACPI INT3403 thermal driver to retrieve temperature data
from the INT3403 ACPI device object present on some systems.
- introduce debug statement for thermal core and step_wise governor.
- assorted fixes and cleanups for thermal core, cpu cooling, exynos
thrmal, intel powerclamp and imx thermal driver"

The adapter is freed before we check its flags. It was caused
by commit 144be3d ("net/cxgb4: Avoid disabling PCI device for
towice"). The problem was reported by Intel's "0-day" tool.
The patch fixes it to avoid reverting commit 144be3d.
