But... in this particular patch kmap_prot needs to be in arch/microblaze/include/asm/highmem.h to preserve bisect-ability. So there would be an inversion with this define and the core #ifndef... I like the change but I'm going to add this change as a follow on patch because at the end of the series microblaze no longer needs this. If this is reasonable could I get a review on this patch to add to the next series?
