Subject: [GIT PULL] x86/asm changes for v5.4

Linus,

Please pull the latest x86-asm-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-asm-for-linus

   # HEAD: e86c2c8b9380440bbe761b8e2f63ab6b04a45ac2 x86/umip: Add emulation (spoofing) for UMIP covered instructions in 64-bit processes as well

The changes in this cycle were:

 - 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.

 Thanks,

	Ingo
