MIPS: dump_tlb: Dump FrameMask register if exists
The FrameMask register is relevant to the TLB so it should be dumped by dump_tlb_regs(), however it is only present in certain cores (r10000, r12000, r14000, r16000). Add dumping of it, conditional upon current_cpu_type(). Suggested-by: Joshua Kinard <kumba@gentoo.org> Suggested-by: Maciej W.
