Subject: [PATCH v2 0/5] mm: arch/shstk: Common shadow stack mapping helper and VM_NOHUGEPAGE
Date: Wed, 25 Feb 2026 16:13:57 +0000 [thread overview]
Message-ID: <20260225161404.3157851-1-catalin.marinas@arm.com> (raw)
This is v2 of the series extracting the common shadow stack mmap into a
separate helper for arm64, riscv and x86. Thanks for the review.
Andrew, if you are happy with this, I think taking the patches through
the mm tree makes most sense.
Minor changes since v1:
- Removed #ifdef from the helper function declaration
- Used two tabs for the alignment of multi-line function arguments
- Added "There is no functional change" to the arch patches log
- Collected ack/review/test tags
v1:

Catalin Marinas (5):
mm: Introduce vm_mmap_shadow_stack() as a helper for VM_SHADOW_STACK
mappings
arm64: gcs: Use the new common vm_mmap_shadow_stack() helper
riscv: shstk: Use the new common vm_mmap_shadow_stack() helper
x86: shstk: Use the new common vm_mmap_shadow_stack() helper
mm: Do not map the shadow stack as THP
