Subject: [PATCH v4 3/4] x86/boot/compressed: Mark process_mem_region() index __maybe_unused
Date: Mon, 9 Nov 2026 13:48:20 +0100 [thread overview]
Message-ID: <20261109124816.61438-9-blum@kernel.org> (raw)
In-Reply-To: <20261109124816.61438-6-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.
