* The trace_hardirqs_off will use CALLER_ADDR0 and CALLER_ADDR1.
* If from user mode there is only one stack frame on the stack, and
* accessing CALLER_ADDR1 will cause oops. So we need create a dummy
* stack frame to make trace_hardirqs_off happy.
*
* This is handy because we also need to save a bunch of GPRs,
* r3 can be different from GPR3(r1) at this point, r9 and r11
* contains the old MSR and handler address respectively,
* r4 & r5 can contain page fault arguments that need to be passed
* along as well. r12, CCR, CTR, XER etc... are left clobbered as
* they aren't useful past this point (aren't syscall arguments),
* the rest is restored from the exception frame.
