From: Meijing Zhao <[email protected]> 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.
