Commit baf1ed24 ("powerpc/mm: Remove empty hash__ functions") removed some empty hash MMU flushing routines, but got a bit overeager and also removed the call to hash__tlb_flush() from tlb_flush(). In regular use this doesn't lead to any noticable breakage, which is a little concerning. Presumably there are flushes happening via other paths such as arch_leave_lazy_mmu_mode(), and/or a bit of luck. Fix it by reinstating the call to hash__tlb_flush().
