Subject: [PATCH 3/3] arm64: remove early_ioremap_reset() call and __late_* macros
Date: Thu, 9 Jul 2026 02:06:47 +0900 [thread overview]
Message-ID: <20260708170647.362562-4-ekffu200098@gmail.com> (raw)
In-Reply-To: <20260708170647.362562-1-ekffu200098@gmail.com>
On arm64, __early_set_fixmap(), __late_set_fixmap() and
__late_clear_fixmap() are all __set_fixmap(). Calling
early_ioremap_reset() changes nothing. So remove the call and the
macros.
No functional change.
