Merge tag 'powerpc-6.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman:
- Fix crashes on 85xx with some configs since the recent hugepd rework.
- Fix boot warning with hugepages and CONFIG_DEBUG_VIRTUAL on some
platforms.
- Don't enable offline cores when changing SMT modes, to match existing
userspace behaviour.
Thanks to Christophe Leroy, Dr. David Alan Gilbert, Guenter Roeck, Nysal
Jan K.A, Shrikanth Hegde, Thomas Gleixner, and Tyrel Datwyler.
