Subject: [PATCH] powerpc: Fix build error in paravirt.h
Date:   Wed, 20 Jan 2021 14:28:38 +0100

./arch/powerpc/include/asm/paravirt.h:83:44: error: implicit declaration
of function 'smp_processor_id'; did you mean 'raw_smp_processor_id'?

smp_processor_id is defined in linux/smp.h but it is not included.

The build error happens only when the patch is applied to 5.3 kernel but
it only works by chance in mainline.

Fixes: ca3f969dcb11 ("powerpc/paravirt: Use is_kvm_guest() in vcpu_is_preempted()")
