The quilt patch titled
     Subject: mm: trace: decode arm64 and sparc64 VM_ARCH_1 flags
has been removed from the -mm tree.  Its filename was
     mm-trace-decode-arm64-and-sparc64-vm_arch_1-flags.patch

This patch was dropped because it was merged into the mm-stable branch

Subject: mm: trace: decode arm64 and sparc64 VM_ARCH_1 flags
Date: Wed, 2 Sep 2026 14:45:08 +0800

Patch series "mm: trace: decode architecture-specific VMA flags", v2.

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.


This patch (of 3):

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.
