Subject: [PATCH v2 0/6] x86/cpu: Do some janitorial work
Date: Thu, 27 Jan 2022 12:56:20 +0100 [thread overview]
Message-ID: <20220127115626.14179-1-bp@alien8.de> (raw)
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"
