From: Borislav Petkov <bp@suse.de>
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"
