#     Merge tag 'powerpc-5.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
#     
#     Pull powerpc fixes from Michael Ellerman:
#     
#      - Fix an existing bug in our user access handling, exposed by one of
#        the bug fixes we merged this cycle.
#     
#      - A fix for a boot hang on 32-bit with CONFIG_TRACE_IRQFLAGS and the
#        recently added CONFIG_VMAP_STACK.
#     
#     Thanks to: Christophe Leroy, Guenter Roeck.
