ARM: nommu: add stub local_flush_bp_all() for !CONFIG_MMUU
Since the merging of Will's tlb-ops branch, specifically 89c7e4b8bbb3
(ARM: 7661/1: mm: perform explicit branch predictor maintenance when required),
building SMP without CONFIG_MMU has been broken.
The local_flush_bp_all function is only called for operations related to
changing the kernel's view of memory and ASID rollover - both of which are
irrelevant to an !MMU kernel.
This patch adds a stub local_flush_bp_all() function to the other tlb
maintenance stubs and restores the ability to build an SMP !MMU kernel.
