Merge tag 'powerpc-5.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman:
"One non-fix, the conversion of vio_driver->remove() to return void,
which touches various powerpc specific drivers.
Fix the privilege checks we do in our perf handling, which could cause
soft/hard lockups in some configurations.
Fix a bug with IRQ affinity seen on kdump kernels when CPU 0 is
offline in the second kernel.
Fix missed page faults after mprotect(..., PROT_NONE) on 603 (32-bit).
Fix a bug in our VSX (vector) instruction emulation, which should only
be seen when doing VSX ops to cache inhibited mappings.
Three commits fixing various build issues with obscure configurations.
Thanks to Athira Rajeev, Cédric Le Goater, Christophe Leroy, Christoph
Plattner, Greg Kurz, Jordan Niethe, Laurent Vivier, Ravi Bangoria,
Tyrel Datwyler, and Uwe Kleine-König"
