Paolo,
Please do a pull from my kvm-ppc-next branch to get a PPC update for
4.12. The main things this time are, in summary:
- Better machine check handling for HV KVM
- Ability to support guests with threads=2, 4 or 8 on POWER9
- Fix for a race that could cause delayed recognition of signals
- Fix for a bug where POWER9 guests could sleep with interrupts
pending.
There will be one merge conflict in include/uapi/linux/kvm.h where you
will need to adjust the capability number assignments that I chose.
There is a one-line addition to arch/powerpc/kernel/mce.c, adding an
EXPORT_SYMBOL_GPL, which was acked by Michael Ellerman. I do not
expect it to cause a conflict in the merge into Linus' tree.
Thanks,
Paul.
