KVM breaking the ppc64_defconfig UP build

[Michael Ellerman]

Hi guys,

The ppc64_defconfig build with CONFIG_SMP=n (ie. UP) is broken by KVM:

  arch/powerpc/kvm/book3s_hv.c:1855:2: error: implicit declaration of function 'inhibit_secondary_onlining'
  arch/powerpc/kvm/book3s_hv.c:1862:2: error: implicit declaration of function 'uninhibit_secondary_onlining'

http://kisskb.ellerman.id.au/kisskb/buildresult/8400164/

The fix for that is fairly easy.


Once that's fixed there is breakage in arch/powerpc/kvm/book3s_hv_interrupts.S
caused by us calling smp_send_reschedule() to cause a self-IPI on 970.

It's not clear to me how we fix that one, any ideas?

cheers
