This series of patches are follow up work (and depends on) Toshi Kani <toshi.k...@hpe.com>'s patches "fix memory leak/ panic in ioremap huge pages".
This series of patches are tested on 4.9 kernel with Cortex-A75 based SoC. These patches can also go into '-stable' branch (if accepted) for 4.6 onwards. >From V7->V8: - Properly fixed compilation issue in x86 file >From V6->V7: - Fixed compilation issue in x86 case - V6 patches were not properly enumarated >From V5->V6: - Use __flush_tlb_kernel_pgtable() for both PUD and PMD. Remove "bool tlb_inv" based variance as it is not need now - Re-naming for consistency >From V4->V5: - Add new API __flush_tlb_kernel_pgtable(unsigned long addr) for kernel addresses >From V3->V4: - Add header for 'addr' in x86 implementation - Re-order pmd/pud clear and table free - Avoid redundant TLB invalidatation in one perticular case >From V2->V3: - Use the exisiting page table free interface to do arm64 specific things >From V1->V2: - Rebased my patches on top of "[PATCH v2 1/2] mm/vmalloc: Add interfaces to free unmapped page table" - Honored BBM for ARM64 Chintan Pandya (4): ioremap: Update pgtable free interfaces with addr arm64: tlbflush: Introduce __flush_tlb_kernel_pgtable arm64: Implement page table free interfaces Revert "arm64: Enforce BBM for huge IO/VMAP mappings" arch/arm64/include/asm/tlbflush.h | 6 ++++++ arch/arm64/mm/mmu.c | 37 +++++++++++++++++++++++++------------ arch/x86/mm/pgtable.c | 8 +++++--- include/asm-generic/pgtable.h | 8 ++++---- lib/ioremap.c | 4 ++-- 5 files changed, 42 insertions(+), 21 deletions(-) -- Qualcomm India Private Limited, on behalf of Qualcomm Innovation Center, Inc., is a member of Code Aurora Forum, a Linux Foundation Collaborative Project
