Allow user space to determine if a disk supports Asynchronous Notification of
media changes. This is done by adding a new sysfs file "capability_flags",
which is documented in (insert file name). This sysfs file will export all
disk capabilities flags to user space. We also define a new flag to define
the media change notification capability.Signed-off-by: Kristen Carlson Accardi

The wrong lookup flag was tested in ->create() causing havoc (error or

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. This results in a stuck for ever call to
smp_call_function_single() on an offline CPU.Ignore the bogus information and print a kernel error to remind ACPI
folks to fix it.Signed-off-by: Thomas Gleixner

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().Signed-off-by: Gautham 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

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.

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.Signed-off-by: Rafael 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. 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.Signed-off-by: Rafael J. Wysocki

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. (This has been confirmed
on an afflicted IBM blade)[libata serverworks.c never trusts the BIOS in the first place so is
accidentally immune]Signed-off-by: Alan Cox

This patch (as905) removes a micro-optimization from the hub port
initialization code. Previously we had been using a short timeout on

standard timeout length.It's not clear that the short timeout ever provided any benefit. And
now we know of one case where it actually hurts: The device can't meet
the short timeout and then it gets terminally confused.This fixes Bugzilla #8444.
