MIPS: Netlogic: Enable SUE bit in cores
Enable Speculative Unmap Enable bit, which will enable speculative L2 cache requests for unmapped memory. This should give better performance for kernel code/data which is in KSEG0 Signed-off-by: Jayachandran C <jchandra@broadcom.com> Patchwork: http://patchwork.linux-mips.org/patch/4461 Signed-off-by: John Crispin <blogic@openwrt.org>
