You implemented transparent huge pages for MIPS:

MIPS: Transparent Huge Pages support
but THP also changed in 3.8:
commit fc9fe822f7112db23e51e2be3b886f5d8f0afdb6
Author: Kirill A. Shutemov <kirill.shutemov@linux.intel.com>
Date: Wed Dec 12 13:50:51 2012 -0800
thp: copy_huge_pmd(): copy huge zero page
This added the requirement for pfn_pmd(), which is only defined if
CONFIG_64BIT && !CONFIG_CPU_VR41XX.
Ben.
