Subject: x86/mm: Add the 'nopcid' boot option to turn off PCID
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=902a5c3e2b4a68f070f1627d921d919a919f984a;p=pandora-kernel.git

x86/mm: Add the 'nopcid' boot option to turn off PCID

commit 0790c9aad84901ca1bdc14746175549c8b5da215 upstream.

The parameter is only present on x86_64 systems to save a few bytes,
as PCID is always disabled on x86_32.
