#     powerpc/ftrace: Fix stack teardown in ftrace_no_trace
#     
#     Commit 41a506ef71eb ("powerpc/ftrace: Create a dummy stackframe to fix
#     stack unwind") added use of a new stack frame on ftrace entry to fix
#     stack unwind. However, the commit missed updating the offset used while
#     tearing down the ftrace stack when ftrace is disabled. Fix the same.
#     
#     In addition, the commit missed saving the correct stack pointer in
#     pt_regs. Update the same.
#
