Since last time:
- Split out KVM parts. Technically they don't actually have
dependencies with the Linux patches I suppose, so they could be
merged via different trees. Logically I think they are better to
stay together.
- Fix and simplify the KVM secondary thread management patch, thanks
Gautham.
- Fixed a bug in the ESL=0 avoid overhead patch.
- Retested on P8 and P9 with qemu.
- Mambo simulator still doesn't handle EC=0 wakeups properly, but I
have reported that, and managed to write a patch here to fix the
simulator bug and test there too.
Nicholas Piggin (14):
powerpc/64s: masked interrupt avoid branch
powerpc/64s: masked interrupt avoid instruction
powerpc/64s: masked interrupt returns to kernel so avoid r13 restore
powerpc/64: cleanup __check_irq_replay
powerpc/64s: irq replay merge HV and non-HV paths for doorbell replay
powerpc/64s: irq replay external use the HV handler in HV mode on
POWER9
powerpc/64: remove redundant instruction in interrupt replay
powerpc/64s: irq replay remove spurious irq reason
powerpc/64: runlatch CTRL[RUN] set optimisation
KVM: PPC: Book3S HV: POWER9 does not require secondary thread
management
powerpc/64s: idle POWER9 can execute stop without a sync sequence
KVM: PPC: Book3S HV: POWER9 can execute stop without a sync sequence
powerpc/64s: idle POWER9 can execute stop in virtual mode
powerpc/64s: idle ESL=0 stop can avoid MSR and save/restore overhead
