#     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.
