Subject: [patch 07/12] acpi: flush TLB when pagetable changed
Date: Wed, 23 Feb 2005 01:53:05 -0800 [thread overview]
Message-ID: <200502230953.j1N9rJiZ020708@shell0.pdx.osdl.net> (raw)
From: Li Shaohua <shaohua.li-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>
Possibly it doesn't change anything here (it's low mem), but it's better to
fix it.
