LGTM. I've got these four from Jason A. Donenfeld queued up in 
tip:WIP.x86/asm:

 bd5b1283e41c: ("crypto: Curve25519 - do not pollute dispatcher based on assembler")
 829f32d78588: ("crypto: X86 - rework configuration, based on Kconfig")
 95ef9f80ed63: ("x86/build: Probe assembler from Kconfig instead of Kbuild")
 1651e700664b: ("x86: Fix bitops.h warning with a moved cast")

I suppose these might interact (maybe even conflict), and are topically 
related.

Would you like to pull these into the kbuild tree? You can find them in:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/asm

Thanks,
