From 9bd860cae3c46a83371ce899ae0d665b6e253687 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Wed, 15 Jul 2015 16:17:46 +0100 Subject: [PATCH] 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 Suggested-by: Maciej W. Rozycki Signed-off-by: James Hogan Cc: Joshua Kinard Cc: Maciej W.
