The radix guest code can has fewer restrictions about what context it can run in, so move this flushing out of assembly and have it use the Linux TLB flush implementations introduced previously. This allows powerpc:tlbie trace events to be used. This changes the tlbiel sequence to only execute RIC=2 flush once on the first set flushed, then RIC=0 for the rest of the sets. The end result of the flush should be unchanged. This matches the local PID flush pattern that was introduced in a5998fcb ("powerpc/mm/radix: Optimise tlbiel flush all case"). Signed-off-by:
