Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
"Two fixes for the VMWare guest support:
- Unbreak VMWare platform detection which got wreckaged by converting
an integer constant to a string constant.
- Fix the clang build of the VMWAre hypercall by explicitely
specifying the ouput register for INL instead of using the short
form"
* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/cpu/vmware: Fix platform detection VMWARE_PORT macro
x86/cpu/vmware: Use the full form of INL in VMWARE_HYPERCALL, for clang/llvm
