Merge tag 'powerpc-5.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:

 - A fix for undetected data corruption on Power9 Nimbus <= DD2.1 in the
   emulation of VSX loads. The affected CPUs were not widely available.

 - Two fixes for machine check handling in guests under PowerVM.

 - A fix for our recent changes to SMP setup, when
   CONFIG_CPUMASK_OFFSTACK=y.

 - Three fixes for races in the handling of some of our powernv sysfs
   attributes.

 - One change to remove TM from the set of Power10 CPU features.

 - A couple of other minor fixes.

Thanks to: Aneesh Kumar K.V, Christophe Leroy, Ganesh Goudar, Jordan
Niethe, Mahesh Salgaonkar, Michael Neuling, Oliver O'Halloran, Qian Cai,
