This series of patches are follow up work (and depends on) Toshi Kani <toshi.kani@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.
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"
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
