Implement global TLB flushing for MN10300.  This will be used by the AM34 which
is SMP capable.

David Howells 492e675116 MN10300: Rename __flush_tlb*() to local_flush_tlb*()
Rename __flush_tlb*() to local_flush_tlb*() as it's more appropriate, and ready
to differentiate local from global TLB flushes when SMP is introduced.

Whilst we're at it, get rid of __flush_tlb_global() and make
local_flush_tlb_page() take an mm_struct pointer rather than VMA pointer.

Rusty Russell 7ce1df49e1 cpumask: use mm_cpumask() wrapper: mn10300
Makes code futureproof against the impending change to mm->cpu_vm_mask
(to be a pointer).

It's also a chance to use the new cpumask_ ops which take a pointer
(the older ones are deprecated, but there's no hurry for arch code).

Also change the actual arg name here to "mm" (which it is), not "task".
