Subject: [stable 3.1] [PATCH] powerpc/kvm: Fix build failure with HV KVM and CBE
Date: Thu, 10 Nov 2011 11:04:56 +1100 [thread overview]
Message-ID: <18823.1320883496@neuling.org> (raw)

powerpc/kvm: Fix build failure with HV KVM and CBE
When running with HV KVM and CBE config options enabled, I get
build failures like the following:
arch/powerpc/kernel/head_64.o: In function `cbe_system_error_hv':
(.text+0x1228): undefined reference to `do_kvm_0x1202'
arch/powerpc/kernel/head_64.o: In function `cbe_maintenance_hv':
(.text+0x1628): undefined reference to `do_kvm_0x1602'
arch/powerpc/kernel/head_64.o: In function `cbe_thermal_hv':
(.text+0x1828): undefined reference to `do_kvm_0x1802'
This is because we jump to a KVM handler when HV is enabled, but we
only generate the handler with PR KVM mode.
