Subject: [PATCH v6 08/30] mm: remove arch vma_alloc_zeroed_movable_folio overrides
Date: Mon, 11 May 2026 04:53:29 -0400	[thread overview]
Message-ID: <24a1b25f4f1cf31fc5bc053e475958ed5e1bf8bd.1778488966.git.mst@redhat.com> (raw)
In-Reply-To: <cover.1778488966.git.mst@redhat.com>

Now that the generic vma_alloc_zeroed_movable_folio() uses
__GFP_ZERO, the arch-specific macros on alpha, m68k, s390, and
x86 that did the same thing are redundant.  Remove them.

arm64 is not affected: it has a real function override that
handles MTE tag zeroing, not just __GFP_ZERO.
