Merge branch 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 asm updates from Ingo Molnar:
- Add UMIP emulation/spoofing for 64-bit processes as well, because of
Wine based gaming.
- Clean up symbols/labels in low level asm code
- Add an assembly optimized mul_u64_u32_div() implementation on x86-64.
* 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/umip: Add emulation (spoofing) for UMIP covered instructions in 64-bit processes as well
x86/asm: Make some functions local labels
x86/asm/suspend: Get rid of bogus_64_magic
x86/math64: Provide a sane mul_u64_u32_div() implementation for x86_64
