This moves things around such that _tlbie is now defined in hash_low_32.S and is only used by the 32-bit hash code, and all nohash CPUs use the various _tlbil_* forms that are now moved to a new file, tlb_nohash_low.S. I moved all the definitions for that stuff out of include/asm/tlbflush.h as they are really internal mm stuff, into mm/mmu_decl.h The code should have no functional changes. I kept some variants inline for trivial forms on things like 40x and 8xx. Signed-off-by: Benjamin Herrenschmidt Acked-by: Kumar Gala Signed-off-by: Paul Mackerras --- Reading git-diff-tree failed
