Subject: [PATCH v3 1/2] arm64/arch_timer: include <linux/percpu.h>
Date: Fri, 3 May 2024 17:18:46 +0000 [thread overview]
Message-ID: <20240503171847.68267-1-puranjay@kernel.org> (raw)
arch_timer.h includes linux/smp.h since the commit:
6acc71ccac7187fc ("arm64: arch_timer: Allows a CPU-specific erratum to only affect a subset of CPUs")
It was included to use DEFINE_PER_CPU(), etc. But It should have
included <linux/percpu.h> rather than <linux/smp.h>. It worked because
smp.h includes percpu.h.
The next commit will remove percpu.h from smp.h and it will break this
usage.
Explicitly include percpu.h and remove smp.h
