From: Borislav Petkov <bp@suse.de>
Hi all,
here's v2 with some adjustments due to dependent changes which went upstream, in the meantime. I figure I should send them out one more time before I queue them.
Also, patch 1 handles printing of naked feature numbers for which we don't generate a string for /proc/cpuinfo now too.
Thx.
changelog: ----------
v1 --
Beef up clearcpuid= so that it supports the strings from /proc/cpuinfo too and remove a bunch of useless, and, in some cases even downright dangerous, chicken bits we have added over the years.
Borislav Petkov (6): x86/cpu: Allow feature bit names from /proc/cpuinfo in clearcpuid= x86/cpu: Remove "nosep" x86/cpu: Remove CONFIG_X86_SMAP and "nosmap" x86/cpu: Remove "nosmep" x86/cpu: Remove "noexec" x86/cpu: Remove "noclflush"
