Subject[PATCH v4 0/3] Fix issues with huge mapping in ioremap for ARM64
Date
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.

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 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
