Hi Jason,

I have your patches on my radar.

I have not checked your Kconfig changes are really working, especially
I looked at [2] and comment on this.

I would have expected your arch/x86/Kconfig.assembler file as
arch/x86/crypto/Kconfig (source include needs to be adapted in
arch/x86/Kconfig).
What about a commit subject like "x86: crypto: Probe assembler options
via Kconfig instead of makefile"?
Not sure if the commit message needs some massage?

Maybe this is all irrelevant when Masahiro has commented.

Thanks.
