Subject: [PATCH v3 3/4] x86/boot/compressed: Mark process_mem_region() index __maybe_unused
Date: Mon, 9 Nov 2026 01:55:31 +0100 [thread overview]
Message-ID: <20261109005528.3477-9-blum@kernel.org> (raw)
In-Reply-To: <20261109005528.3477-6-blum@kernel.org>
The local index variable i in process_mem_region() is unused when either
CONFIG_MEMORY_HOTREMOVE or CONFIG_ACPI is disabled.
Mark it __maybe_unused accordingly.
