Subject: [PATCH 3/6] x86/cpu: proc - remove "wp" status line in cpuinfo
Date: Sun, 12 Feb 2017 22:12:09 +0100 [thread overview]
Message-ID: <1486933932-585-4-git-send-email-minipli@googlemail.com> (raw)
In-Reply-To: <1486933932-585-1-git-send-email-minipli@googlemail.com>
As of commit a5c2a893dbd4 ("x86, 386 removal: Remove
CONFIG_X86_WP_WORKS_OK") the kernel won't boot if CR0.WP isn't working
correctly. This makes a process reading this file always see "wp : yes"
here -- otherwise there would be no process to begin with ;)
As this status line in /proc/cpuinfo serves no purpose for quite some
time now, get rid of it.
