Guest r8 register is held in the scratch register and stored correctly,
so remove the instruction that clobbers it. Guest r13 was missing from vcpu,
store it there.

I'm not sure I can follow you here. The code that leads up to this is:
#define NORMAL_EXCEPTION_PROLOG(intno) \
mtspr SPRN_SPRG_WSCRATCH0, r10; /* save one register */ \
mfspr r10, SPRN_SPRG_THREAD; \
stw r11, THREAD_NORMSAVE(0)(r10); \
stw r13, THREAD_NORMSAVE(2)(r10); \
mfcr r13; /* save CR in r13 for now */\
mfspr r11, SPRN_SRR1; \
DO_KVM BOOKE_INTERRUPT_##intno SPRN_SRR1; \
See the subject line -- this is for level exceptions
(EXC_LEVEL_EXCEPTION_PROLOG), not normal exceptions.
Ah, my bad. Sorry.
Thanks, applied to kvm-ppc-next.
