Merge tag 'powerpc-4.10-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes friom Michael Ellerman: "Apologies for the late pull request, but Ben has been busy finding bugs. - Userspace was semi-randomly segfaulting on radix due to us incorrectly handling a fault triggered by autonuma, caused by a patch we merged earlier in v4.10 to prevent the kernel executing userspace. - We weren't marking host IPIs properly for KVM in the OPAL ICP backend. - The ERAT flushing on radix was missing an isync and was incorrectly marked as DD1 only. - The powernv CPU hotplug code was missing a wakeup type and failing to flush the interrupt correctly when using OPAL ICP Thanks to Benjamin Herrenschmidt" * tag 'powerpc-4.10-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/powernv: Properly set "host-ipi" on IPIs powerpc/powernv: Fix CPU hotplug to handle waking on HVI powerpc/mm/radix: Update ERAT flushes when invalidating TLB powerpc/mm: Fix spurrious segfaults on radix with autonuma
