powerpc/mm/hash: Abstract context id allocation for KVM
KVM wants to be able to allocate an MMU context id, which it does currently by calling __init_new_context(). We're about to rework that code, so provide a wrapper for KVM so it can not worry about the details. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
