We do that by allocating one vsid context for each 512TB range. More details of that is explained in patch 3. Changes from V3: * move extended_id to be a union with mm_context_t id. This reduce some array index complexity. * Add addr_limit check when handling slb miss for extended context Changes from V2: * Rebased on top of slice_mask series from Nick Piggin * Fixed segfault when mmap with 512TB hint address Aneesh Kumar K.V (3): powerpc/mm: Add support for handling > 512TB address in SLB miss powerpc/mm/hash64: Increase the VA range powerpc/mm/hash: Don't memset pgd table if not needed arch/powerpc/include/asm/book3s/64/hash-4k.h | 6 + arch/powerpc/include/asm/book3s/64/hash-64k.h | 7 +- arch/powerpc/include/asm/book3s/64/mmu-hash.h | 6 +- arch/powerpc/include/asm/book3s/64/mmu.h | 26 ++++- arch/powerpc/include/asm/book3s/64/pgalloc.h | 13 ++- arch/powerpc/include/asm/processor.h | 16 ++- arch/powerpc/kernel/exceptions-64s.S | 12 +- arch/powerpc/mm/copro_fault.c | 2 +- arch/powerpc/mm/hash_utils_64.c | 4 +- arch/powerpc/mm/init_64.c | 6 - arch/powerpc/mm/mmu_context_book3s64.c | 15 ++- arch/powerpc/mm/pgtable-hash64.c | 2 +- arch/powerpc/mm/pgtable_64.c | 5 - arch/powerpc/mm/slb.c | 154 ++++++++++++++++++++++++++ arch/powerpc/mm/slb_low.S | 6 +- arch/powerpc/mm/tlb_hash64.c | 2 +- 16 files changed, 252 insertions(+), 30 deletions(-) -- 2.14.3
