From 8aa2a4178dc535591ac0c17de45b14fe7f6a05c7 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 14 Aug 2023 10:18:42 +0200 Subject: x86/apic: Use u32 for cpu_present_to_apicid() 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 and fixup a few related usage sites for consistency sake.
