Subject: [PATCH] powerpc/kvm: Fix build error on book3s_hv.c
Date: Wed, 11 May 2016 11:15:55 +1000 [thread overview]
Message-ID: <1462929355-30681-1-git-send-email-gwshan@linux.vnet.ibm.com> (raw)
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").
