Merge tag 'powerpc-5.9-3' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:

 - Add perf support for emitting extended registers for power10.

 - A fix for CPU hotplug on pseries, where on large/loaded systems we
   may not wait long enough for the CPU to be offlined, leading to
   crashes.

 - Addition of a raw cputable entry for Power10, which is not required
   to boot, but is required to make our PMU setup work correctly in
   guests.

 - Three fixes for the recent changes on 32-bit Book3S to move modules
   into their own segment for strict RWX.

 - A fix for a recent change in our powernv PCI code that could lead to
   crashes.

 - A change to our perf interrupt accounting to avoid soft lockups when
   using some events, found by syzkaller.

 - A change in the way we handle power loss events from the hypervisor
   on pseries. We no longer immediately shut down if we're told we're
   running on a UPS.

 - A few other minor fixes.
