Merge branch 'x86-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 AVX512 status update from Ingo Molnar:
"This adds a new ABI that the main scheduler probably doesn't want to
deal with but HPC job schedulers might want to use: the
AVX512_elapsed_ms field in the new /proc/<pid>/arch_status task status
file, which allows the user-space job scheduler to cluster such tasks,
to avoid turbo frequency drops"
* 'x86-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
Documentation/filesystems/proc.txt: Add arch_status file
x86/process: Add AVX-512 usage elapsed time to /proc/pid/arch_status
proc: Add /proc/<pid>/arch_status
