[PATCH RESEND 1/3] mm: trace: decode arm64 and sparc64 VM_ARCH_1 flags

[Meijing Zhao <zhaomeijing100@gmail.com>]

From: Meijing Zhao <zhaomeijing@lixiang.com>

The VM_ARCH_1 bit has architecture-specific meanings.  show_vma_flags(),
which is used by VMA tracepoints and %pGv, already reports the powerpc,
parisc and no-MMU meanings, but falls back to the generic "arch_1" name
on arm64 and sparc64.

Report VM_ARM64_BTI as "bti" and VM_SPARC_ADI as "adi" so trace output
and %pGv dumps expose the actual architecture-specific state.  These
names also match the mnemonics used by /proc/<pid>/smaps.
