MIPS: Refactor dumping of TLB registers for r3k/r4k
The TLB registers are dumped in a couble of places: - sysrq_tlbdump_single() - when dumping TLB state. - do_mcheck() - in response to a machine check error. The main TLB registers also differ between r3k and r4k, but r4k appears to be assumed. Refactor this code into a dump_tlb_regs() function, implemented for both r3k and r4k, and used by both of the above functions. Fixes: d1e9a4f54735 ("MIPS: Add SysRq operation to dump TLBs on all CPUs") Suggested-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: Maciej W.
