Subject: [PATCH][2.6] VR41xx pte fix and VR413x cpu-probe fix
Date: Tue, 30 Dec 2003 21:24:29 +0100 [thread overview]
Message-ID: <20031230202429.GA11117@sonycom.com> (raw)
Hi,
here are two patches related to the VR41xx series. The first patch
fixes the pte calculation (pte_pfn and pfn_pte) for VR41xx. Second
patch fixes the cpu detection for the VR413x cpu's (missing break).
