Quite a few functions that get called from the tlb gather code require that preemption must be disabled. So disable preemption inside of the called functions instead. The only drawback is that rcu_table_freelist_finish() doesn't get necessarily called on the cpu(s) that filled the free lists. So we may see a delay, until we finally see an rcu callback. However over time this shouldn't matter. So we get rid of lots of "BUG: using smp_processor_id() in preemptible" messages. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> |
