b7cdd9e632 staging: delete gma500 driver
It's now "properly" merged into the DRM tree in the kernel, so delete
the staging version of the driver as it is far obsolete and broken.

982d411c30 A few small WM8994 updates to go on top of the previous lot of things
that were sent.  They collide with some -next work so I'd really like to
 get them into 3.3-rc3 if possible to merge back up into the -next code.
 All driver specific and unexciting in the grand scheme of things.

2492250e44 ALSA: oxygen, virtuoso: fix exchanged L/R volumes of aux and CD inputs
The driver accidentally exchanged the left/right fields for stereo AC'97
mixer registers.  This affected only the aux and CD inputs because the
line input bypasses the AC'97 codec and the mic input is mono; cards
without AC'97 (Xonar DS/DG/HDAV Slim, HG2PCI, HiFier) were not affected.

Use IP_FREEBIND socket option so that iscsi portal configuration with
explicit IP addresses can happen during boot, before network interfaces
have been assigned IPs.

This is especially important on systemd based Linux boxes where system
boot happens asynchronously and non-trivial configuration must be done
to get targetcli.service to start synchronously after the network is
configured.

735703cac0 target: Fix target_submit_cmd() exception handling
This patch fixes a bug in target_submit_cmd() where the failure path
for transport_generic_allocate_tasks() made a direct call to
transport_send_check_condition_and_sense() and not calling the
final target_put_sess_cmd() release callback.

For transport_generic_allocate_tasks() failures, use the proper call to
transport_generic_request_failure() to handle kref_put() along
with potential internal queue full response processing.

It also makes transport_lookup_cmd_lun() failures in
target_submit_cmd() use transport_send_check_condition_and_sense() and
target_put_sess_cmd() directly to avoid se_cmd->se_dev reference in
transport_generic_request_failure() handling.

Finally it drops the out_check_cond: label and use direct reference for
allocate task failures, and per-se_device queue_full handling is
currently not supported for transport_lookup_cmd_lun() failure
descriptors due to se_device dependency.

1edcdb497e target: Change target_submit_cmd() to return void
Retval not very useful, and may even be harmful. Once submitted, fabrics
should expect a sense error if anything goes wrong. All fabrics checking
of this retval are useless or broken:

fc checks it just to emit more debug output.
ib_srpt trickles retval up, then it is ignored.
qla2xxx trickles it up, which then causes a bug because the abort goto
in qla_target.c thinks cmd hasn't been sent to target.

Just returning nothing is best.

95fe1ee41e target: accept REQUEST_SENSE with 18bytes
WindowsXP+BOT issues a MODE_SENSE request with page 0x1c which is not
suppoerted by target. Target rejects that command with
TCM_INVALID_CDB_FIELD, so far so good. On BOT I can't send the SENSE
response back, instead I can only reply that an error occured. The next
thing happens is a REQUEST_SENSE request with 18 bytes length. Since the
check here is more than 18 bytes I have to NACK that request as well.
This is not really required: We check for some additional room, but we
never use it. The additional length is set to 0xa so the total length is
0xa + 8 = 18 which is fine with my 18 bytes.

db91ff55bd md: two small fixes to handling interrupt resync.
1/ If a resync is aborted we should record how far we got
 (recovery_cp) the last request that we know has completed
 (->curr_resync_completed) rather than the last request that was
 submitted (->curr_resync).

2/ When a resync aborts we still want to update the metadata with
 any changes, so set MD_CHANGE_DEVS even if we 'skip'.

96e02d1586 exec: fix use-after-free bug in setup_new_exec()
Setting the task name is done within setup_new_exec() by accessing
bprm->filename. However this happens after flush_old_exec().
This may result in a use after free bug, flush_old_exec() may
"complete" vfork_done, which will wake up the parent which in turn
may free the passed in filename.
To fix this add a new tcomm field in struct linux_binprm which
contains the now early generated task name until it is used.

Fixes this bug on s390:

Power management fixes for 3.3-rc3

Three power management regression fixes, one for a recent regression introcuded
by the freezer changes during the 3.3 merge window and two for regressions
in cpuidle (resulting from PM QoS changes) and in the hibernate user space
interface, both introduced during the 3.2 development cycle.

They include:

* Two hibernate (s2disk) regression fixes from Srivatsa S. Bhat (for
 regressions introduced during the 3.3 merge window and during the 3.2
 development cycle).

* A cpuidle fix from Venki Pallipadi for a regression resulting from PM QoS
 changes during the 3.2 development cycle causing cpuidle to work incorrectly
 for CONFIG_PM unset.

d020283dc6 PM / QoS: CPU C-state breakage with PM Qos change
Looks like change "PM QoS: Move and rename the implementation files"
merged during the 3.2 development cycle made PM QoS depend on
CONFIG_PM which depends on (PM_SLEEP || PM_RUNTIME).

That breaks CPU C-states with kernels not having these CONFIGs, causing CPUs
to spend time in Polling loop idle instead of going into deep C-states,
consuming way way more power. This is with either acpi idle or intel idle
enabled.

Either CONFIG_PM should be enabled with any pm_qos users or
the !CONFIG_PM pm_qos_request() should return sane defaults not to break
the existing users. Here's is the patch for the latter option.

[rjw: Modified the changelog slightly.]

Srivatsa S. Bhat
379e0be812 PM / Freezer: Thaw only kernel threads if freezing of kernel threads fails
If freezing of kernel threads fails, we are expected to automatically
thaw tasks in the error recovery path. However, at times, we encounter
situations in which we would like the automatic error recovery path
to thaw only the kernel threads, because we want to be able to do
some more cleanup before we thaw userspace. Something like:

error = freeze_kernel_threads();
if (error) {
	/* Do some cleanup */

	/* Only then thaw userspace tasks*/
	thaw_processes();
}

An example of such a situation is where we freeze/thaw filesystems
during suspend/hibernation. There, if freezing of kernel threads
fails, we would like to thaw the frozen filesystems before thawing
the userspace tasks.

So, modify freeze_kernel_threads() to thaw only kernel threads in
case of freezing failure. And change suspend_freeze_processes()
accordingly. (At the same time, let us also get rid of the rather
cryptic usage of the conditional operator (:?) in that function.)

[rjw: In fact, this patch fixes a regression introduced during the
 3.3 merge window, because without it thaw_processes() may be called
 before swsusp_free() in some situations and that may lead to massive
 memory allocation failures.]
