#     powerpc/64: Use barrier_nospec in syscall entry
#     
#     On powerpc syscall entry is done in assembly so patch in an explicit
#     barrier_nospec.
#

#     [mpe: Move the barrier to immediately prior to the vulnerable load,
#           and add a comment trying to explain why. Drop the barrier from
#           syscall_dotrace, because that syscall number comes from the
#           kernel.]
