[PATCH] x86: update AS_* macros to binutils >=2.23, supporting ADX and AVX2

From: Jason A. Donenfeld
Date: Thu Mar 26 2020 - 16:26:15 EST

Next message: MickaÃl SalaÃn: "[PATCH v15 00/10] Landlock LSM"
Previous message: Kees Cook: "Re: [RFC v3 1/2] kernel/sysctl: support setting sysctl parameters from kernel command line"
In reply to: Nick Desaulniers: "Re: [PATCH v2 15/16] x86: update AS_* macros to binutils >=2.23, supporting ADX and AVX2"
Next in thread: Nick Desaulniers: "Re: [PATCH] x86: update AS_* macros to binutils >=2.23, supporting ADX and AVX2"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Now that the kernel specifies binutils 2.23 as the minimum version, we
can remove ifdefs for AVX2 and ADX throughout.

Masahiro - here's an updated patch based on -next, as Nick requested.
Whether or not you'd prefer this one to the other one based on Linus'
tree is up to you, but here it is in case it's helpful.
