# commit: 0138ba5783ae0dcc799ad401a1e8ac8333790df9
# powerpc/64/signal: Balance return predictor
# stack in signal trampoline.
#
# The kernel places an additional brctl instruction
# in the vdso to call the user handler.
#
# And then this commit:
#
# commit 24321ac668e452a4942598533d267805f291fdc9
# powerpc/64/signal: Fix regression in
# __kernel_sigtramp_rt64() semantics
#
# updates the semantics of __kernel_sigtramp_rt64().
# It added a new symbol to serve as a jump target from
# the kernel to the trampoline.
#
# The net result of these changes is that gdb stops
# at __kernel_start_sigtramp_rt64. Need to do one
# more stepi to reach the expected location in the user
# signal handler.
