commit 07f8ab255fcc0bce1fabc8fb35ace4f0f5d2ac67 upstream.
When CONFIG_KVM_XICS is enabled, CPU_UP_PREPARE and other macros for
CPU states in linux/cpu.h are needed by arch/powerpc/kvm/book3s_hv.c.
Otherwise, build error as below is seen:
gwshan@gwshan:~/sandbox/l$ make arch/powerpc/kvm/book3s_hv.o
:
CC arch/powerpc/kvm/book3s_hv.o
arch/powerpc/kvm/book3s_hv.c: In function ‘kvmppc_cpu_notify’:
arch/powerpc/kvm/book3s_hv.c:3072:7: error: ‘CPU_UP_PREPARE’ \
undeclared (first use in this function)
This fixes the issue introduced by commit <6f3bb80944> ("KVM: PPC:
Book3S HV: kvmppc_host_rm_ops - handle offlining CPUs").
Fixes: 6f3bb8094414
