MIPS: Fix crash registers on non-crashing CPUs

2017-06-20T12:04:52Z

commit c80e1b62ffca52e2d1d865ee58bc79c4c0c55005 upstream. As part of handling a crash on an SMP system, an IPI is send to all other CPUs to save their current registers and stop. It was using task_pt_regs(current) to get the registers, but that will only be accurate if the CPU was interrupted running in userland. Instead allow the architecture to pass in the registers (all pass NULL now, but allow for the future) and then use get_irq_regs() which should be accurate as we are in an interrupt. Fall back to task_pt_regs(current) if nothing else is available.

Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle
