Subject: [PATCH v2 3/4] x86/boot/compressed: Mark process_mem_region() index __maybe_unused
Date: Wed, 24 Jun 2026 14:02:57 +0200	[thread overview]
Message-ID: <20260624120300.590233-9-thorsten.blum@linux.dev> (raw)
In-Reply-To: <20260624120300.590233-6-thorsten.blum@linux.dev>

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.
