Apart from adding a VMA flag readable name for trace purpose, this series
does some open encoding replacements with availabe VMA specific wrappers.
This skips VM_HUGETLB check in vma_migratable() as its already being done
with another patch (https://patchwork.kernel.org/patch/11347831/) which
is yet to be merged.
This series applies on 5.6-rc3. This has been build tested on multiple
platforms, though boot and runtime testing was limited to arm64 and x86.

Changes in V2:
- Dropped patch [PATCH 4/5] mm/vma: Replace....vma_set_anonymous() per Kirril
- Dropped braces around is_vm_hugetlb_page() in kvmppc_e500_shadow_map()
- Replaced two open encodings in mm/mmap.c with vma_is_accessible()
- Added hugetlb headers to prevent build failures wrt is_vm_hugetlb_page()
Changes in V1: (https://patchwork.kernel.org/cover/11385219/)
Anshuman Khandual (4):
mm/vma: Add missing VMA flag readable name for VM_SYNC
mm/vma: Make vma_is_accessible() available for general use
mm/vma: Replace all remaining open encodings with is_vm_hugetlb_page()
mm/vma: Replace all remaining open encodings with vma_is_anonymous()

Lets move vma_is_accessible() helper to include/linux/mm.h which makes it
available for general use. While here, this replaces all remaining open
encodings for VMA access check with vma_is_accessible().
