The old NO_IRQ define some platforms had was long ago declared obsolete and wrong. FRV should therefore not be re-introducing this, especially as IRQs are usually unsigned in the kernel. The "no IRQ" case is defined to be zero and Linus made this rather clear at the time. arch/frv shows no dependancy on this but it might show up driver fixes needing doing I guess Signed-off-by: NAlan Cox <alan@redhat.com> Acked-by: NDavid Howells <dhowells@redhat.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

由 Srivatsa Vaddagiri 提交于
Sukadev Bhattiprolu reported a kernel crash with control groups. There are couple of problems discovered by Suka's test: - The test requires the cgroup filesystem to be mounted with atleast the cpu and ns options (i.e both namespace and cpu controllers are active in the same hierarchy). # mkdir /dev/cpuctl # mount -t cgroup -ocpu,ns none cpuctl (or simply) # mount -t cgroup none cpuctl -> Will activate all controllers in same hierarchy. - The test invokes clone() with CLONE_NEWNS set. This causes a a new child to be created, also a new group (do_fork->copy_namespaces->ns_cgroup_clone-> cgroup_clone) and the child is attached to the new group (cgroup_clone-> attach_task->sched_move_task). At this point in time, the child's scheduler related fields are uninitialized (including its on_rq field, which it has inherited from parent). As a result sched_move_task thinks its on runqueue, when it isn't. As a solution to this problem, I moved sched_fork() call, which initializes scheduler related fields on a new task, before copy_namespaces(). I am not sure though whether moving up will cause other side-effects. Do you see any issue? - The second problem exposed by this test is that task_new_fair() assumes that parent and child will be part of the same group (which needn't be as this test shows). As a result, cfs_rq->curr can be NULL for the child. The solution is to test for curr pointer being NULL in task_new_fair(). With the patch below, I could run ns_exec() fine w/o a crash.

PREEMPT_RESTRICT was a method aimed at reducing the amount of wakeup related preemption. It has a disadvantage though, it can prevent legitimate wakeups if a task is 'unlucky' to be hit too early by a tick that clears peer_preempt. Now that the wakeup preemption has been cleaned up we dont seem to have excessive preemptions anymore, so this feature can be turned off.

Since powerpc started using CONFIG_GENERIC_CLOCKEVENTS, the deterministic CPU accounting (CONFIG_VIRT_CPU_ACCOUNTING) has been broken on powerpc, because we end up counting user time twice: once in timer_interrupt() and once in update_process_times(). This fixes the problem by pulling the code in update_process_times that updates utime and stime into a separate function called account_process_tick. If CONFIG_VIRT_CPU_ACCOUNTING is not defined, there is a version of account_process_tick in kernel/timer.c that simply accounts a whole tick to either utime or stime as before. If CONFIG_VIRT_CPU_ACCOUNTING is defined, then arch code gets to implement account_process_tick. This also lets us simplify the s390 code a bit; it means that the s390 timer interrupt can now call update_process_times even when CONFIG_VIRT_CPU_ACCOUNTING is turned on, and can just implement a suitable account_process_tick(). account_process_tick() now takes the task_struct * as an argument. Tested both with and without CONFIG_VIRT_CPU_ACCOUNTING. Signed-off-by: NPaul Mackerras <paulus@samba.org> Signed-off-by: NIngo Molnar <mingo@elte.hu>

we lost the sched_min_granularity tunable to a clever optimization that uses the sched_latency/min_granularity ratio - but the ratio is quite unintuitive to users and can also crash the kernel if the ratio is set to 0.

Credit goes to juergen.kadidlo@exasol.com for diagnosing this issue and supplying the initial patch. blk_queue_invalidate_tags() must use the proper requeueing paths instead of open coding the re-add of the request, otherwise we bug out in rq accounting. Just switch to using blk_requeue_request(), that takes care of end-tag handling as well and also adds the blktrace REQUEUE notify event that is also appropriate here.

One-shot timer mode on PXA has various bugs which prevent kernels build with NO_HZ enabled booting. They end up spinning on a permanently asserted timer interrupt because we don't properly clear it down - clearing the OIER bit does not stop the pending interrupt status. Fix this in the set_mode handler as well. Moreover, the code which sets the next expiry point may race with the hardware, and we might not set the match register sufficiently in the future. If we encounter that situation, return -ETIME so the generic time code retries.

For kernel addresses between TASK_SIZE and PAGE_OFFSET, flush_tlb_kern_range() does not work as would be expected. The TLB invalidate works with a matching ASID, or on entries marked as global. The set_pte_at() macro marks addresses >= PAGE_OFFSET as global, but not addresses from TASK_SIZE to PAGE_OFFSET, which are also kernel addresses. The result is that the entries in this range are not actually invalidated by flush_tlb_kern_range(). This patch instead marks addresses >= TASK_SIZE as global.
