I *think* this is because VIRT_CPU_ACCOUNTING_GEN accounts everything in nsec instead of jiffies and this could be very expensive on 32bit archs doing 64bit math. Frederic, is this everything or is there more to it? >Thanks for any feedback > >Best regards > >Mathias Sebastian -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
