Subject[GIT PULL] x86/asm changes for v4.20
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: ec3a94188df7d28b374868d9a2a0face910e62ab x86/fsgsbase/64: Clean up various details

The main changes in this cycle were the fsgsbase related preparatory
patches from Chang S. Bae - but there's also an optimized
memcpy_flushcache() and a cleanup for the __cmpxchg_double() assembly
glue.

Thanks,

Ingo
