Merge branch 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fpu updates from Ingo Molnar:
"Three changes:
- preparatory patch for AVX state tracking that computing-cluster
folks would like to use for user-space batching - but we are not
happy about the related ABI yet so this is only the kernel tracking
side
- a cleanup for CR0 handling in do_device_not_available()
- plus we removed a workaround for an ancient binutils version"
* 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/fpu: Track AVX-512 usage of tasks
x86/fpu: Get rid of CONFIG_AS_FXSAVEQ
x86/traps: Have read_cr0() only once in the #NM handler
