  The function virt_to_phys was defined to virt_to_phys and then
implemented right below.

I can't understand why, just drop it and let the actual function
slot in.

Fixes: dfad83cb7193 ("MIPS: Add support for CONFIG_DEBUG_VIRTUAL")

Oh that's a nice patch!

Sure, no point in causing stir with Jiaxun's work, let's drop
this patch.
