Kevin Hao 2cd76629f6 powerpc/trace: Add a dummy stack frame for trace_hardirqs_off ... The trace_hardirqs_off will use CALLER_ADDR0 and CALLER_ADDR1. If an exception occurs in user mode, there is only one stack frame on the stack and accessing the CALLER_ADDR1 will causes the following call trace. So we create a dummy stack frame to make trace_hardirqs_off happy.
