Hello, This series mostly consisting of code movement. One new thing added in this series is to switch book3s 64 to 4 level page table. The changes are done to accomodate the upcoming new memory model in future powerpc chips. The details of the new MMU model can be found at
http://ibm.biz/power-isa3 (Needs registration). I am including a summary of the changes below. ISA 3.0 adds support for the radix tree style of MMU with full virtualization and related control mechanisms that manage its coexistence with the HPT. Radix-using operating systems will manage their own translation tables instead of relying on hcalls. Radix style MMU model requires us to do a 4 level page table with 64K and 4K page size. The table index size different page size is listed below PGD -> 13 bits PUD -> 9 (1G hugepage) PMD -> 9 (2M huge page) PTE -> 5 (for 64k), 9 (for 4k) We also require the page table to be in big endian format. Changes from V3: * rebase on top of PTE bits movement patch series * Drop all the hash linux abstraction patches * Keep only 4 level table and other code movement patches. Changes from V2: * rebase to latest kernel * Update commit messages * address review comments Changes from V1: * move patches adding helpers to the next series NOTE: This is lightly tested. Right now 4K linux page size is what is being tested. Once that is done I will have to do 64K linux page size tests. -aneesh Aneesh Kumar K.V (17): powerp/mm: Update code comments powerpc/mm: add _PAGE_HASHPTE similar to 4K hash powerpc/mm: Split pgtable types to separate header powerpc/mm: Don't have conditional defines for real_pte_t powerpc/mm: Switch book3s 64 with 64K page size to 4 level page table powerpc/mm: Update masked bits for linux page table powerpc/mm: Copy pgalloc (part 1) powerpc/mm: Copy pgalloc (part 2) powerpc/mm: Copy pgalloc (part 3) powerpc/mm: Hugetlbfs is book3s_64 and fsl_book3e (32 or 64) powerpc/mm: Use flush_tlb_page in ptep_clear_flush_young powerpc/mm: Move hash related mmu-*.h headers to book3s/ powerpc/mm: Create a new headers for tlbflush for hash64 powerpc/mm: Move hash page table related functions to pgtable-hash64.c powerpc/mm: THP is only available on hash64 as of now powerpc/mm: Use generic version of pmdp_clear_flush_young powerpc/mm: Move hash64 specific definitions to separate header Kirill A.
