Subject: [patch V5 05/39] x86/microcode: Provide CONFIG_MICROCODE_INITRD32
Date: Tue, 17 Oct 2023 23:23:29 +0200 (CEST) [thread overview]
Message-ID: <20231017211722.236208250@linutronix.de> (raw)
In-Reply-To: 20231017200758.877560658@linutronix.de
From: Thomas Gleixner <tglx@linutronix.de>
Create an aggregate config switch which covers X86_32, MICROCODE and
BLK_DEV_INITRD to avoid lengthy #ifdeffery in upcoming code.
