2010-10-29MIPS: Honor L2 bypass bitKevin Cernekee1-4/+30
On many of the newer MIPS32 cores, CP0 CONFIG2 bit 12 (L2B) indicates that the L2 cache is disabled and therefore Linux should not attempt to use it. [Ralf: Moved the code added by Kevin's original patch into a separate function that can easily be replaced for platforms that need more a different probe.] Signed-off-by: Kevin Cernekee <cernekee@gmail.com> Cc: linux-mips@linux-mips.org> Cc: <linux-kernel@vger.kernel.org> Patchwork: https://patchwork.linux-mips.org/patch/1723/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
