From 6a4be6984595b164b6f281c5b242dbdf1c06d528 Mon Sep 17 00:00:00 2001 From: Andrew Cooper Date: Mon, 22 May 2023 11:57:38 +0100 Subject: [PATCH] x86/apic: Fix use of X{,2}APIC_ENABLE in asm with older binutils "x86/smpboot: Support parallel startup of secondary CPUs" adds the first use of X2APIC_ENABLE in assembly, but older binutils don't tolerate the UL suffix. Switch to using BIT() instead.
