MIPS fails to build with:

arch/mips/mm/tlb-r4k.c: In function 'r4k_tlb_uniquify':
arch/mips/mm/tlb-r4k.c:591:17: error: passing argument 1 of

     MIPS: mm: kmalloc tlb_vpn array to avoid stack overflow

It seems like we might have to cast to a phys_addr_t before passing that 
to memblock_free().
