2007-05-23prohibit rcutorture from being compiled into the kernelPaul E. McKenney
There have been a number of instances where people have accidentally compiled rcutorture into the kernel (CONFIG_RCU_TORTURE_TEST=y), which has never been useful, and has often resulted in great frustration. The attached patch prohibits rcutorture from being compiled into the kernel. It may be excluded altogether or compiled as a module. People wishing to have rcutorture hammer their machine immediately upon boot are free to hand-edit lib/Kconfig.debug to remove the "depends on m" line. Thanks to Randy Dunlap for the trick that makes this work. Signed-off-by: Paul E.

2007-05-23Ignore bogus ACPI info for offline CPUsThomas Gleixner
Booting a SMP kernel with maxcpus=1 on a SMP system leads to a hard hang, because ACPI ignores the maxcpus setting and sends timer broadcast info for the offline CPUs.

2007-05-23freezer: move frozen_process() to kernel/power/process.cGautham R Shenoy
Other than refrigerator, no one else calls frozen_process(). So move it from include/linux/freezer.h to kernel/power/process.c. Also, since a task can be marked as frozen by itself, we don't need to pass the (struct task_struct *p) parameter to frozen_process().

2007-05-23freezer: fix PF_NOFREEZE vs freezeable raceGautham R Shenoy
This patch fixes the race pointed out by Oleg Nesterov. * Freezer marks a thread as freezeable. * The thread now marks itself PF_NOFREEZE, but it will be frozen on on calling try_to_freeze(). Thus the task is frozen, even though it doesn't want to. * Subsequent thaw_processes() will also fail to thaw the task since it is marked PF_NOFREEZE. Avoid this problem by checking the task's PF_NOFREEZE status in frozen_processes() before marking the task as frozen. Signed-off-by: Gautham R Shenoy <ego@in.ibm.com> Signed-off-by: Rafael J.

2007-05-23freezer: fix kthread_create vs freezer theoretical raceOleg Nesterov
kthread() sleeps in TASK_INTERRUPTIBLE state waiting for the first wakeup. In theory, this wakeup may come from freeze_process()->signal_wake_up(), so the task can disappear even before kthread_create() sets its ->comm. Change kthread() to use TASK_UNINTERRUPTIBLE.

2007-05-23freezer: take kernel_execve into considerationRafael J. Wysocki
Kernel threads can become userland processes by calling kernel_execve(). In particular, this may happen right after the try_to_freeze_tasks() called with FREEZER_USER_SPACE has returned, so try_to_freeze_tasks() needs to take userspace processes into consideration even if it is called with FREEZER_KERNEL_THREADS.

2007-05-23freezer: fix vfork problemRafael J. Wysocki
Currently try_to_freeze_tasks() has to wait until all of the vforked processes exit and for this reason every user can make it fail. To fix this problem we can introduce the additional process flag PF_FREEZER_SKIP to be used by tasks that do not want to be counted as freezable by the freezer and want to have TIF_FREEZE set nevertheless. Then, this flag can be set by tasks using sys_vfork() before they call wait_for_completion(&vfork) and cleared after they have woken up. After clearing it, the tasks should call try_to_freeze() as soon as possible. Signed-off-by: Rafael J.

2007-05-23freezer: close potential race between refrigerator and thaw_tasksRafael J. Wysocki
If the freezing of tasks fails and a task is preempted in refrigerator() before calling frozen_process(), then thaw_tasks() may run before this task is frozen. In that case the task will freeze and no one will thaw it. To fix this race we can call freezing(current) in refrigerator() along with frozen_process(current) under the task_lock() which also should be taken in the error path of try_to_freeze_tasks() as well as in thaw_process(). Moreover, if thaw_process() additionally clears TIF_FREEZE for tasks that are not frozen, we can be sure that all tasks are thawed and there are no pending "freeze" requests after thaw_tasks() has run.

It turns out from customer reports to Red Hat and some PCI dumps that the MegaIDE in RAID mode doesn't provide the drive tuning data that the serverworks driver expects but sometimes does provide something that fools the code. For the RAID class case skip the oem setup and don't trust the BIOS data. We then tune from scratch and this sorts it out.
