MIPS: Move generated code to .text for microMIPS 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.

MIPS: Export tlbmiss_handler_setup_pgd near its definition We export tlbmiss_handler_setup_pgd in arch/mips/mm/tlbex.c close to a declaration of it, rather than close to its definition as is standard. We've supported exporting symbols in assembly code since commit 22823ab419d8 ("EXPORT_SYMBOL() for asm"), so move the export to follow the function's (stub) definition.

MIPS: mm: Fix broken microMIPS kernel regression. Commit f4ae17aa0f2122b52f642985b46210a1f2eceb0a [MIPS: mm: Use scratch for PGD when !CONFIG_MIPS_PGD_C0_CONTEXT] broke microMIPS kernel builds. This patch refactors that code similar to what was done for the 'clear_page' and 'copy_page' functions. Signed-off-by: Steven J.
