Subject: [patch v2 16/38] x86/apic: Use u32 for [gs]et_apic_id()
Date: Fri, 28 Jul 2023 14:13:02 +0200 (CEST) [thread overview]
Message-ID: <20230728120930.562193563@linutronix.de> (raw)
In-Reply-To: <20230728105650.565799744@linutronix.de>
APIC IDs are used with random data types u16, u32, int, unsigned int,
unsigned long.
Make it all consistently use u32 because that reflects the hardware
register width.
Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
