[PATCH resend] MIPS: Get rid of some #ifdefery in arch/mips/mm/tlb-r4k.c

[David Daney <ddaney.cavm@gmail.com>]

From: David Daney <david.daney@cavium.com>

In the case of !CONFIG_HUGETLB_PAGE, in linux/hugetlb.h we have this
definition:

 #define pmd_huge(x)    0

The other huge page constants in the if(pmd_huge()) block are likewise
defined, so we can get rid of the #ifdef CONFIG_HUGETLB_PAGE an let
the compiler optimize this block away instead.  Doing this the code
has a much cleaner appearance.

Signed-off-by: David Daney <david.daney@cavium.com>

The first attempt as sending the patch resulted in a corrupt change
log, no change other than correcting the log.
