[PATCH 0/6] x86/cpu: Do some janitorial work

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

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.

Thx.

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"
