Subject: [patch] pae: build fix
Date: Wed, 22 Jun 2005 16:00:25 +0200 [thread overview]
Message-ID: <20050622140025.GA31707@bytesex> (raw)
Hi,
The patch below is needed to make pae-enabled xen build. Not
sure why the intpte_t cast was added and whenever it is a good
idea to remove it. Problem is that PAGE_MASK is used to
page-align both physical and virtual addresses, and the cast
causes build failures for the virtual address case.
Comments?
Gerd
