[Chintan Pandya]

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

Chintan Pandya (3):
  ioremap: Update pgtable free interfaces with addr
  arm64: Implement page table free interfaces
  Revert "arm64: Enforce BBM for huge IO/VMAP mappings"

>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
