"This contains mostly various fixes, cleanups and some conversions to
the atomic API. One noteworthy change is that PWM consumers can now
pass a hint to the PWM core about the PWM usage, enabling PWM

There's also a fair bit of simplification here with the addition of
some device-managed helpers as well as unification between the DT and

"Fixes and improvements for FPU handling on x86:
- Prevent sigaltstack out of bounds writes.
The kernel unconditionally writes the FPU state to the alternate
stack without checking whether the stack is large enough to
accomodate it.
Check the alternate stack size before doing so and in case it's too
small force a SIGSEGV instead of silently corrupting user space
data.
- MINSIGSTKZ and SIGSTKSZ are constants in signal.h and have never
been updated despite the fact that the FPU state which is stored on
the signal stack has grown over time which causes trouble in the
field when AVX512 is available on a CPU. The kernel does not expose
the minimum requirements for the alternate stack size depending on
the available and enabled CPU features.
ARM already added an aux vector AT_MINSIGSTKSZ for the same reason.
Add it to x86 as well.
- A major cleanup of the x86 FPU code. The recent discoveries of
XSTATE related issues unearthed quite some inconsistencies,
duplicated code and other issues.
The fine granular overhaul addresses this, makes the code more
robust and maintainable, which allows to integrate upcoming XSTATE
related features in sane ways"

nfsd: fix NULL dereference in nfs3svc_encode_getaclres
In error cases the dentry may be NULL.
Before 751cdcfceaac, the encoder also checked dentry and
d_really_is_positive(dentry), but that looks like overkill to me--zero
status should be enough to guarantee a positive dentry.
This isn't the first time we've seen an error-case NULL dereference
hidden in the initialization of a local variable in an xdr encoder. But
I went back through the other recent rewrites and didn't spot any
similar bugs.

PCI: xgene: Annotate __iomem pointer
"bar_addr" is passed as the argument to writel(), which expects a
"void __iomem *". Annotate "bar_addr" correctly. Resolves an sparse
"incorrect type in argument 2 (different address spaces)" warning.

Pull tty / serial updates from Greg KH:
"Here is the big set of tty and serial driver patches for 5.14-rc1.
A bit more than normal, but nothing major, lots of cleanups.
Highlights are:
- lots of tty api cleanups and mxser driver cleanups from Jiri
- build warning fixes
- various serial driver updates
- coding style cleanups
- various tty driver minor fixes and updates
- removal of broken and disable r3964 line discipline (finally!)
All of these have been in linux-next for a while with no reported
issues"

Pull staging / IIO driver updates from Greg KH:
"Here is the big set of IIO and staging driver patches for 5.14-rc1.
Loads of IIO driver updates and additions in here, the shortlog has
the full details.
For the staging side, we moved a few drivers out of staging, and
deleted the kpc2000 drivers as the original developer asked us to
because no one was working on them anymore.
Also in here are loads of coding style cleanups due to different
intern projects focusing on the staging tree to try to get experience
doing kernel development.
All of these have been in the linux-next tree for a while with no
reported problems"
