Since commit 656c21d6af5d ("powerpc/shared: Use static key to detect
shared processor") and 14c73bd344da ("powerpc/vcpu: Assume dedicated
processors as non-preempt"), powerpc test builds may fail with the
following build errors.
./arch/powerpc/include/asm/spinlock.h:39:1: error:
type defaults to ‘int’ in declaration of ‘DECLARE_STATIC_KEY_FALSE’
./arch/powerpc/include/asm/spinlock.h: In function ‘vcpu_is_preempted’:
./arch/powerpc/include/asm/spinlock.h:44:7: error:
implicit declaration of function ‘static_branch_unlikely’
./arch/powerpc/include/asm/spinlock.h:44:31: error:
‘shared_processor’ undeclared
The offending commits use static_branch_unlikely and shared_processor
without adding the include file declaring it.
