tlb-r3k has debug code hidden under DEBUG_TLB define. This flag
is undefined by default which results in the code not being compiled.
If one would enable the flag, the file would not build because of
the code being not up to date with the rest of this file.

This commit fixes the normally hidden debug code to bring it in line
with the rest of the file and make it build with the debug flag enabled.

running checkpatch over your patch gives me

WARNING: printk() should include KERN_<LEVEL> facility level
#29: FILE: arch/mips/mm/tlb-r3k.c:80:
+		printk("[tlbrange<%llu,0x%08lx,0x%08lx>]",


can you fix that as well ? Maybe be even  replacing printk with
pr_debug 

Thomas.
