Subject: [PATCH V2 0/4] mm/vma: Use all available wrappers when possible

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.
