#     Merge tag 'powerpc-5.15-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
#     
#     Pull powerpc fixes from Michael Ellerman:
#     
#      - Fix a bug where guests on P9 with interrupts passed through could get
#        stuck in synchronize_irq().
#     
#      - Fix a bug in KVM on P8 where secondary threads entering a guest would
#        write outside their allocated stack.
#     
#      - Fix a bug in KVM on P8 where secondary threads could confuse the host
#        offline code and cause the guest or host to crash.
#     
#     Thanks to Cédric Le Goater.
