Subject: [PATCH 1/5] x86: change_page_attr_clear fix
Date: Thu, 31 Jan 2008 15:35:59 +0800 [thread overview]
Message-ID: <1201764959.12950.22.camel@caritas-dev.intel.com> (raw)
This patch replaces __change_page_attr_set_clr() with
change_page_attr_set_clr() in change_page_attr_clear() to flush the
TLB/cache properly.
