powerpc/8xx: make user addr DTLB miss the short path User space DTLB miss represent approximatly 90% of TLB misses so make it the shortest path. Also remove an unneccessary double jump in FixupDAR Before this patch, we spend 3.3 TB ticks in the handler for each user address miss and 3.4 TB ticks for each kernel address miss After this patch, we send 3.0 TB ticks in the handler for each user address miss and 3.9 TB ticks for each kernel address miss Taking into account that user misses represent 90% of the total, this patch provides an improvement of approx. 9% Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Scott Wood <oss@buserror.net>
