Subject: [PATCH 0/6] x86/cpu: Do some janitorial work
Date: Fri, 12 Nov 2021 11:32:40 +0100 [thread overview]
Message-ID: <20211112103246.7555-1-bp@alien8.de> (raw)
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"
