Some TLB flush operations can flush other CPUs. The problem with this is they used non-synced variants of flushes (i.e., that return before the destination has completed the flush). Since all TLB flush users need the _synced variants, and that last user (ppc) of the non-synced flush was buggy, this is a footgun waiting to go off. There do not seem to be any callers that flush other CPUs, so remove the capability. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Nicholas Piggin <npiggin@gmail.com>
