[PATCH] MIPS: mm: remove comment referring to removed CONFIG_MIPS_CMP

[PATCH] MIPS: mm: remove comment referring to removed CONFIG_MIPS_CMP

[Ethan Nelson-Moore]

CMP support was removed in commit 7fb6f7b0af67 ("MIPS: Remove
deprecated CONFIG_MIPS_CMP"), but a comment referring to it remained in
arch/mips/mm/c-r4k.c. Remove it.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
