2017-09-06mips: Save all registers when saving the frameCorey Minyard
The MIPS frame save code was just saving a few registers, enough to do a backtrace if every function set up a frame. However, this is not working if you are using DWARF unwinding, because most of the registers are wrong. This was causing kdump backtraces to be short or bogus. So save all the registers.

2011-06-15MIPS: Add new unwind_stack variantDaniel Kalmar
The unwind_stack_by_address variant supports unwinding based on any kernel code address. This symbol is also exported so it can be called from modules.
