Naveen N. Rao a4979a7e71 powerpc/ftrace: Pass the correct stack pointer for DYNAMIC_FTRACE_WITH_REGS 
For DYNAMIC_FTRACE_WITH_REGS, we should be passing-in the original set
of registers in pt_regs, to capture the state _before_ ftrace_caller.
However, we are instead passing the stack pointer *after* allocating a
stack frame in ftrace_caller. Fix this by saving the proper value of r1
in pt_regs. Also, use SAVE_10GPRS() to simplify the code.
