[PATCH RESEND 0/3] mm: trace: decode architecture-specific VMA flags

[Meijing Zhao <zhaomeijing100@gmail.com>]

From: Meijing Zhao <zhaomeijing@lixiang.com>

show_vma_flags(), which is used by VMA tracepoints and %pGv, names
generic VM_* bits but does not fully decode architecture-specific flag
positions.  As a result, trace output and VMA dumps can show a generic
"arch_1" name or a raw hexadecimal value instead of the meaning assigned
by the target architecture.

This series adds symbolic names for the arm64 and sparc64 meanings of
VM_ARCH_1, arm64 MTE flags, user shadow stack flags, and protection-key
encoding bits under their corresponding configuration guards.

The original submission was rewritten by the mail gateway as a
multipart HTML message and had a disclaimer appended, causing the vger
mailing lists to reject it.  This resend uses a mail transport that
preserves plain-text messages.  There are no code changes.

Meijing Zhao (3):
  mm: trace: decode arm64 and sparc64 VM_ARCH_1 flags
  mm: trace: decode MTE and shadow stack VMA flags
  mm: trace: name protection key encoding bits
