"So here's my next branch for powerpc. A bit late as I was on vacation
last week. It's mostly the same stuff that was in next already, I
just added two patches today which are the wiring up of lockref for
powerpc, which for some reason fell through the cracks last time and
is trivial.
The highlights are, in addition to a bunch of bug fixes:
- Reworked Machine Check handling on kernels running without a
hypervisor (or acting as a hypervisor). Provides hooks to handle
some errors in real mode such as TLB errors, handle SLB errors,
etc...
- Support for retrieving memory error information from the service
processor on IBM servers running without a hypervisor and routing
them to the memory poison infrastructure.
- _PAGE_NUMA support on server processors
- 32-bit BookE relocatable kernel support
- FSL e6500 hardware tablewalk support
- A bunch of new/revived board support
- FSL e6500 deeper idle states and altivec powerdown support
You'll notice a generic mm change here, it has been acked by the
relevant authorities and is a pre-req for our _PAGE_NUMA support"

Pull powerpc mremap fix from Ben Herrenschmidt:
"This is the patch that I had sent after -rc8 and which we decided to
wait before merging. It's based on a different tree than my -next
branch (it needs some pre-reqs that were in -rc4 or so while my -next
is based on -rc1) so I left it as a separate branch for your to pull.
It's identical to the request I did 2 or 3 weeks back.
This fixes crashes in mremap with THP on powerpc.
The fix however requires a small change in the generic code. It moves
a condition into a helper we can override from the arch which is
harmless, but it *also* slightly changes the order of the set_pmd and
the withdraw & deposit, which should be fine according to Kirill (who
wrote that code) but I agree -rc8 is a bit late...
It was acked by Kirill and Andrew told me to just merge it via powerpc"

powerpc/thp: Fix crash on mremap
@splice_desc.total_len is 32 bit(unsigned int) which is used to store the
size passed from userspace which is 64 bit(size_t) so that the size is
unexpectedly truncated
That means vmsplice can not work if the size passed from userspace is >=
4G, for example, we noticed in vmsplice, splice-reader does not do
anything and splice-writer is waiting for available buffer forever if the
size is 4G
Fix it by extending @splice_desc.total_len to 64 bits as well

- Support interrupt controllers with zero ack base.

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

allowed the work to progress incrementally.
The first patch on this branch just removes the scaffolding, ensuring
we will always get compile errors if people accidentally try the
userspace and the kernel uid and gid types. The second patch an
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"

rcu_dereference_check_fdtable() looks very wrong,
1. rcu_my_thread_group_empty() was added by 844b9a8707 "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().

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"

Pull ACPI and power management updates from Rafael Wysocki:
"As far as the number of commits goes, the top spot belongs to ACPI
this time with cpufreq in the second position and a handful of PM
core, PNP and cpuidle updates. They are fixes and cleanups mostly, as
usual, with a couple of new features in the mix.
The most visible change is probably that we will create struct
acpi_device objects (visible in sysfs) for all devices represented in
the ACPI tables regardless of their status and there will be a new
sysfs attribute under those objects allowing user space to check that
status via _STA.
Consequently, ACPI device eject or generally hot-removal will not
delete those objects, unless the table containing the corresponding
namespace nodes is unloaded, which is extremely rare. Also ACPI
container hotplug will be handled quite a bit differently and cpufreq
will support CPU boost ("turbo") generically and not only in the
acpi-cpufreq driver.
Specifics:
- ACPI core changes to make it create a struct acpi_device object for
every device represented in the ACPI tables during all namespace
scans regardless of the current status of that device. In
accordance with this, ACPI hotplug operations will not delete those
objects, unless the underlying ACPI tables go away.

DT and DT-conversion-related changes for various ARM platforms. Most
of these are to enable various devices on various boards, etc, and not
necessarily worth enumerating.
New boards and systems continue to come in as new devicetree files that
don't require corresponding C changes any more, which is indicating that
the system is starting to work fairly well.
A few things worth pointing out:
* ST Ericsson ux500 platforms have made the major push to move over to fully
support the platform with DT.
* Renesas platforms continue their conversion over from legacy platform devices
to DT-based for hardware description.

Pull ARM SoC DT updates from Olof Johansson:
"DT and DT-conversion-related changes for various ARM platforms. Most
of these are to enable various devices on various boards, etc, and not
necessarily worth enumerating.
New boards and systems continue to come in as new devicetree files
that don't require corresponding C changes any more, which is
indicating that the system is starting to work fairly well.
A few things worth pointing out:
* ST Ericsson ux500 platforms have made the major push to move over
to fully support the platform with DT
* Renesas platforms continue their conversion over from legacy
platform devices to DT-based for hardware description"

This is the branch where we usually queue up cleanup efforts, moving
drivers out of the architecture directory, header file restructuring,
etc. Sometimes they tangle with new development so it's hard to keep it
strictly to cleanups.
Some of the things included in this branch are:
* Atmel SAMA5 conversion to common clock
* Reset framework conversion for tegra platforms
- Some of this depends on tegra clock driver reworks that are shared with Mike
Turquette's clk tree.
* Tegra DMA refactoring, which are shared branches with the DMA tree.
* Removal of some header files on exynos to prepare for multiplatform

Pull audit update from Eric Paris:
"Again we stayed pretty well contained inside the audit system.
Venturing out was fixing a couple of function prototypes which were
inconsistent (didn't hurt anything, but we used the same value as an
int, uint, u32, and I think even a long in a couple of places).
We also made a couple of minor changes to when a couple of LSMs called
the audit system. We hoped to add aarch64 audit support this go
round, but it wasn't ready.
I'm disappearing on vacation on Thursday. I should have internet
access, but it'll be spotty. If anything goes wrong please be sure to
cc rgb@redhat.com. He'll make fixing things his top priority"

For general-purpose (i.e. distro) kernel builds it makes sense to build
with CONFIG_KEXEC to allow end users to choose what kind of things they
want to do with kexec. However, in the face of trying to lock down a
system with such a kernel, there needs to be a way to disable kexec_load
(much like module loading can be disabled). Without this, it is too easy
for the root user to modify kernel memory even when CONFIG_STRICT_DEVMEM
and modules_disabled are set. With this change, it is still possible to
load an image for use later, then disable kexec_load so the image (or lack
of image) can't be altered.
The intention is for using this in environments where "perfect"
enforcement is hard. Without a verified boot, along with verified
modules, and along with verified kexec, this is trying to give a system a
better chance to defend itself (or at least grow the window of
discoverability) against attack in the face of a privilege escalation.
In my mind, I consider several boot scenarios:
1) Verified boot of read-only verified root fs loading fd-based
verification of kexec images.
2) Secure boot of writable root fs loading signed kexec images.
3) Regular boot loading kexec (e.g. kcrash) image early and locking it.
4) Regular boot with no control of kexec image at all.
1 and 2 don't exist yet, but will soon once the verified kexec series has
landed. 4 is the state of things now. The gap between 2 and 4 is too
large, so this change creates scenario 3, a middle-ground above 4 when 2
and 1 are not possible for a system.

We can kill either task->did_exec or PF_FORKNOEXEC, they are mutually
