Prepare of a next patch which will call tlbmiss_handler_setup_pgd on microMIPS. MicroMIPS complains if the called code s not in the .text section. To fix this we generate code into space reserved in arch/mips/mm/tlb-funcs.S While there, move the rest of the generated functions (handle_tlbl, handle_tlbs, handle_tlbm) to the same file.
