Pull x86 fixes from Thomas Gleixner:
"This contains the following fixes and improvements:
- Avoid dereferencing an unprotected VMA pointer in the fault signal
generation code
- Fix inline asm call constraints for GCC 4.4
- Use existing register variable to retrieve the stack pointer
instead of forcing the compiler to create another indirect access
which results in excessive extra 'mov %rsp, %<dst>' instructions
- Disable branch profiling for the memory encryption code to prevent
an early boot crash
- Fix a sparse warning caused by casting the __user annotation in
__get_user_asm_u64() away
- Fix an off by one error in the loop termination of the error patch
in the x86 sysfs init code
- Add missing CPU IDs to various Intel specific drivers to enable the
functionality on recent hardware
- More (init) constification in the numachip code"

Pull timer fixes from Thomas Gleixner:
"This adds a new timer wheel function which is required for the
conversion of the timer callback function from the 'unsigned long
data' argument to 'struct timer_list *timer'. This conversion has two
benefits:
1) It makes struct timer_list smaller
2) Many callers hand in a pointer to the timer or to the structure
containing the timer, which happens via type casting both at setup
and in the callback. This change gets rid of the typecasts.
Once the conversion is complete, which is planned for 4.15, the old
setup function and the intermediate typecast in the new setup function
go away along with the data field in struct timer_list.
Merging this now into mainline allows a smooth queueing of the actual
conversion in the affected maintainer trees without creating
dependencies"

Pull smp/hotplug fixes from Thomas Gleixner:
"This addresses the fallout of the new lockdep mechanism which covers
completions in the CPU hotplug code.
The lockdep splats are false positives, but there is no way to
annotate that reliably. The solution is to split the completions for
CPU up and down, which requires some reshuffling of the failure
rollback handling as well"

kernel_waitid() can return a PID, an error or 0. rusage is filled in the first
case and waitid(2) rusage should've been copied out exactly in that case, *not*
whenever kernel_waitid() has not returned an error. Compat variant shares that
braino; none of kernel_wait4() callers do, so the below ought to fix it.

Currently we use current_stack_pointer() function to get the value
of the stack pointer register. Since commit:
f5caf621ee ("x86/asm: Fix inline asm call constraints for Clang")
... we have a stack register variable declared. It can be used instead of
current_stack_pointer() function which allows to optimize away some
excessive "mov %rsp, %<dst>" instructions:
-mov %rsp,%rdx
-sub %rdx,%rax
-cmp $0x3fff,%rax
-ja ffffffff810722fd <ist_begin_non_atomic+0x2d>
+sub %rsp,%rax
+cmp $0x3fff,%rax
+ja ffffffff810722fa <ist_begin_non_atomic+0x2a>
Remove current_stack_pointer(), rename __asm_call_sp to current_stack_pointer
and use it instead of the removed function.

Some routines in mem_encrypt.c are called very early in the boot process,
e.g. sme_encrypt_kernel(). When CONFIG_TRACE_BRANCH_PROFILING=y is defined
the resulting branch profiling associated with the check to see if SME is
active results in a kernel crash. Disable branch profiling for
mem_encrypt.c by defining DISABLE_BRANCH_PROFILING before including any
header files.

Pull keys fixes from James Morris:
"Notable here is a rewrite of big_key crypto by Jason Donenfeld to
address some issues in the original code.
From Jason's commit log:
"This started out as just replacing the use of crypto/rng with
get_random_bytes_wait, so that we wouldn't use bad randomness at
boot time. But, upon looking further, it appears that there were
even deeper underlying cryptographic problems, and that this seems
to have been committed with very little crypto review. So, I rewrote
the whole thing, trying to keep to the conventions introduced by the
previous author, to fix these cryptographic flaws."
There has been positive review of the new code by Eric Biggers and
Herbert Xu, and it passes basic testing via the keyutils test suite.
Eric also manually tested it.
Generally speaking, we likely need to improve the amount of crypto
review for kernel crypto users including keys (I'll post a note
separately to ksummit-discuss)"

These don't seem to change at runtime, and the initialisers
are constant data. This could be improved by not selecting
