Subject: [PATCH 1/2] sparc32: remove redundant memset in arch_mm_preinit()
Date: Thu, 27 Aug 2026 23:54:33 +0900 [thread overview]
Message-ID: <20260827145437.490605-2-ekffu200098@gmail.com> (raw)
In-Reply-To: <20260827145437.490605-1-ekffu200098@gmail.com>
memblock_alloc() returns zeroed memory, so the memset after the
allocation is redundant.
No functional change.
