I goofed up in making a patch file so enumeration is wrong.
I'll upload v7

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