Removes preemption requirement\n\nFrom: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n\nThis patch fixes a bug with cpu bound guest on kvm-s390. Sometimes it\nwas impossible to deliver a signal to a spinning guest. We used\npreemption as a circumvention. The preemption notifiers called\nvcpu_load, which checked for pending signals and triggered a host\nintercept. But even with preemption, a sigkill was not delivered\nimmediately.\n\nThis patch changes the low level host interrupt handler to check for the\nSIE instruction, if TIF_WORK is set. In that case we change the\ninstruction pointer of the return PSW to rerun the vcpu_run loop. The kvm\ncode sees an intercept reason 0 if that happens. This patch adds accounting\nfor these types of intercept as well.\n\nThe advantages:\n- works with and without preemption\n- signals are delivered immediately\n- much better host latencies without preemption\n\nAcked-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nSigned-off-by: Christian Borntraeger \u003cborntraeger@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "2688905e6a9b3647bf7b452cb0ff2bdb166bd8fe", "tree": "389b9c29eaaa7eb49a9e7d3bb601959fb9d27af8", "parents": [ "c0a18111e571138747a98af18b3a2124df56a0d1" ], "author": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Wed May 07 09:22:52 2008 +0200" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Wed May 07 09:23:00 2008 +0200" }, "message": "[S390] s390: Optimize user and work TIF check\n\nOn return from syscall or interrupt, we have to check if we return to\nuserspace (likely) and if there is work todo (less likely) to decide\nif we handle the work.

The \"clockid\"\nparameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME.\n\nThe timerfd_settime() API give new settings by the timerfd fd, by optionally\nretrieving the previous expiration time (in case the \"otmr\" parameter is not\nNULL).\n\nThe time value specified in \"utmr\" is absolute, if the TFD_TIMER_ABSTIME bit\nis set in the \"flags\" parameter. Otherwise it\u0027s a relative time.\n\nThe timerfd_gettime() API returns the next expiration time of the timer, or\n{0, 0} if the timerfd has not been set yet.\n\nLike the previous timerfd API implementation, read(2) and poll(2) are\nsupported (with the same interface).
