Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Ingo Molnar:
"Three changes:
- An UV fix/quirk to pull UV BIOS calls into the efi_runtime_lock
locking regime. (This done by aliasing __efi_uv_runtime_lock to
efi_runtime_lock, which should make the quirk nature obvious and
maintain the general policy that the EFI lock (name...) isn't
exposed to drivers.)
- Our version of MAGA: Make a.out Great Again.
- Add a new Intel model name enumerator to an upstream header to help
reduce dependencies going forward"
* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/platform/UV: Use efi_runtime_lock to serialise BIOS calls
x86/CPU: Add Icelake model number
x86/a.out: Clear the dump structure initially
