Subject: [PATCH] xen: Fix for xen guest with mem > 3.7G
Date: Sun, 14 Sep 2008 07:42:23 -0700 [thread overview]
Message-ID: <48CD22CF.9030900@goop.org> (raw)
In-Reply-To: <20080914132104.GB32106@elte.hu>
PFN_PHYS() can truncate large addresses unless its passed a suitable
large type. This is fixed more generally in the patch series
introducing phys_addr_t, but we need a short-term fix to solve a
regression.
