Subject: [PATCH 2/2] sparc32: remove redundant memset in srmmu_nocache_init()
Date: Thu, 27 Aug 2026 23:54:34 +0900 [thread overview]
Message-ID: <20260827145437.490605-3-ekffu200098@gmail.com> (raw)
In-Reply-To: <20260827145437.490605-1-ekffu200098@gmail.com>
memblock_alloc_or_panic() returns zeroed memory, so the memset after
the allocation is redundant.
No functional change.
