#     Merge tag 'powerpc-5.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
#     
#     Pull powerpc updates from Michael Ellerman:
#     
#      - A large series adding wrappers for our interrupt handlers, so that
#        irq/nmi/user tracking can be isolated in the wrappers rather than
#        spread in each handler.
#     
#      - Conversion of the 32-bit syscall handling into C.
#     
#      - A series from Nick to streamline our TLB flushing when using the
#        Radix MMU.
#     
#      - Switch to using queued spinlocks by default for 64-bit server CPUs.
#     
#      - A rework of our PCI probing so that it happens later in boot, when
#        more generic infrastructure is available.
#     
#      - Two small fixes to allow 32-bit little-endian processes to run on
#        64-bit kernels.
#     
#      - Other smaller features, fixes & cleanups.
