ACPI workqueues aren't used during memory reclaming. Use
alloc_workqueue() to create workqueues w/o rescuers.
If the purpose of the separation between kacpid_wq and kacpi_notify_wq
was to give notifications better response time, kacpi_notify_wq can be
dropped and kacpi_wq can be created with higher @max_active.

aio_wq isn't used during memory reclaim. Convert to alloc_workqueue()
without WQ_MEM_RECLAIM. It's possible to use system_wq but given that
the number of work items is determined from userland and the work item
may block, enforcing strict concurrency limit would be a good idea.
Also, move fput_work to system_wq so that aio_wq is used soley to
throttle the max concurrency of aio work items and fput_work doesn't
interact with other work items.

With cmwq, there's no reason for cpufreq drivers to use separate
workqueues. Remove the dedicated workqueues from cpufreq_conservative
and cpufreq_ondemand and use system_wq instead. The work items are
already sync canceled on stop, so it's already guaranteed that no work
is running on module exit.

With cmwq, there's no reason to use a separate workqueue for mailbox.
Use the system_wq instead. mbox->rxq->work is sync flushed in
omap_mbox_fini() to make sure it's not running on any cpu, which makes
sure that no mbox work is running when omap_mbox_exit() is entered.

Make CIFS mount work in a container.

Teach cifs about network namespaces, so mounting uses adresses/routing
visible from the container rather than from init context.
A container is a chroot on steroids that changes more than just the root
filesystem the new processes see. One thing containers can isolate is
"network namespaces", meaning each container can have its own set of
ethernet interfaces, each with its own own IP address and routing to the
outside world. And if you open a socket in _userspace_ from processes
within such a container, this works fine.
But sockets opened from within the kernel still use a single global
networking context in a lot of places, meaning the new socket's address
and routing are correct for PID 1 on the host, but are _not_ what
userspace processes in the container get to use.
So when you mount a network filesystem from within in a container, the
mount code in the CIFS driver uses the host's networking context and not
the container's networking context, so it gets the wrong address, uses
the wrong routing, and may even try to go out an interface that the
container can't even access... Bad stuff.
This patch copies the mount process's network context into the CIFS
structure that stores the rest of the server information for that mount
point, and changes the socket open code to use the saved network context
instead of the global network context. I.E. "when you attempt to use
these addresses, do so relative to THIS set of network interfaces and
routing rules, not the old global context from back before we supported
containers".
The big long HOWTO sets up a test environment on the assumption you've
never used ocntainers before. It basically says:
1) configure and build a new kernel that has container support
2) build a new root filesystem that includes the userspace container
control package (LXC)
3) package/run them under KVM (so you don't have to mess up your host
system in order to play with containers).
4) set up some containers under the KVM system
5) set up contradictory routing in the KVM system and the container so
that the host and the container see different things for the same address
6) try to mount a CIFS share from both contexts so you can both force it
to work and force it to fail.
For a long drawn out test reproduction sequence, see:

In fs/cifs/cifs_dfs_ref.c::cifs_dfs_do_automount() we have this code:
...
mnt = ERR_PTR(-EINVAL);
if (IS_ERR(tlink)) {
mnt = ERR_CAST(tlink);
goto free_full_path;
}
ses = tlink_tcon(tlink)->ses;
rc = get_dfs_path(xid, ses, full_path + 1, cifs_sb->local_nls,
&num_referrals, &referrals,
cifs_sb->mnt_cifs_flags & CIFS_MOUNT_MAP_SPECIAL_CHR);
cifs_put_tlink(tlink);
mnt = ERR_PTR(-ENOENT);
...
The assignment of 'mnt = ERR_PTR(-EINVAL);' is completely pointless. If we
take the 'if (IS_ERR(tlink))' branch we'll set 'mnt' again and we'll also
do so if we do not take the branch. There is no way we'll ever use 'mnt'
with the assigned 'ERR_PTR(-EINVAL)' value, so we may as well just remove
the pointless assignment.

The probe function adds the MMC host which can start accepting request
immediately. There is an assumption here that no requests happen
immediatly, but it's not always the case. This assumption can causes
a BUG() when the clocks are disabled. The fix is to just remove the
clock disable in the probe function.

The opregion is a shared memory region between ACPI and the graphics
driver. As the ACPI mapping has been changed to cachable in commit
6d5bbf00d251cc73223a71422d69e069dc2e0b8d, mapping the intel opregion
non-cachable now fails. As no bus-master hardware is involved in the
opregion, cachable map should do no harm.

Starting with SandyBridge (though possible with earlier hacked BIOSes),
the BIOS may initialise the IGFX as secondary to a discrete GPU. Prior,
it would simply disable the integrated GPU. So we adjust our PCI class
mask to match any DISPLAY_CLASS device.
In such a configuration, the IGFX is not a primary VGA controller and
so should not take part in VGA arbitration, and the error return from
vga_client_register() is expected.

During suspend, Linus found that his machine would hang for 3 seconds,
and identified that intel_ring_buffer_wait() was the culprit:
"Because from looking at the code, I get the notion that
"intel_read_status_page()" may not be exact. But what happens if that
inexact value matches our cached ring->actual_head, so we never even
try to read the exact case? Does it _stay_ inexact for arbitrarily
long times? If so, we might wait for the ring to empty forever (well,
until the timeout - the behavior I see), even though the ring really
_is_ empty."
As the reported HEAD position is only updated every time it crosses a
64k boundary, whilst draining the ring it is indeed likely to remain one
value. If that value matches the last known HEAD position, we never read
the true value from the register and so trigger a timeout.

Without this change, blits to the front buffer won't invalidate FBC
state, causing us to scan out stale data. Make sure we update these
bits on every FBC enable, since they may get clobbered if we shut off
the display.

Don't reset if the engine isn't busy. This matches the behavior of
previous asics. Reseting a non-hung block can lead to a hang.

Fix a shutdown regression caused by 2a2d31c8dc6f ("intel_idle: open
broadcast clock event"). The clockevent framework can automatically
shutdown broadcast timers for hotremove CPUs. And we get a shutdown
regression when we shutdown broadcast timer for hot remove CPU, so just
delete some code.
Also fix some section mismatch.

When clearing the DMA channel, clear all status bits.
When handling a DMA interrupt, clear only the interrupt
status bits that have been read and are passed to the
channel's interrupt handler, not every status bit.

Earlier patches select HAVE_SCHED_CLOCK for omaps. To have working sched_clock
also for MPU timer, we need to implement it in a way where the right one gets
selected during the runtime.

For omap15xx and 730 we need to use the MPU timer
as the 32K timer is not available. For omap16xx
we want to use the 32K timer because of PM. Fix this
by allowing to build in both timers.
