However, it was brought to my attention that the existing code was a
bit cryptic, so I start by trying to clean up the existing code before
patching it.

The first patch should be purely cosmetic, and the second adds the

I will reply with the two patches.

David Daney (2):
 MIPS: Replace some magic numbers with symbolic values in tlbex.c
 MIPS: Don't branch to eret in TLB refill.
