There are two issues in vmw_kms_update_layout_ioctl(). First, the
for loop forgets to index rects and only checks the first element.
Second, there is a potential integer overflow if userspace passes
in a large arg->num_outputs. The call to kzalloc() would allocate
a small buffer, leading to out-of-bounds read.

Disabling the CRTC by setting its framebuffer to NULL, as used by
drm_framebuffer_cleanup(), was failing to pass the current framebuffer
to the crtc_func->disable callback. This is because of the dance within
drm_crtc_helper_set_config to pass the new_fb (NULL in this case) to the
drm_crtc_helper_set_mode with the currently attached fb as a parameter.
drm_crtc_helper_set_mode treats this as a no-op and the encoder is still
enabled. And so the current fb is forgotten before the call to
drm_helper_disable_unused_functions.
This patch treats disabling the CRTC as a simple special case rather
than adding further complexity into the configuration logic.
This fixes a pin-leak of the fb bo on Xserver close.

This reverts commit df711fc9962b9491af2b92bd0d21ecbfefe4e5fa.
The commit added a reset-on-resume quirk because the NEC chipset stopped
responding to commands about 30 minutes after a system resume from
suspend. We thought it was a chipset issue, but it turns out that the
xHCI driver was zeroing out the link TRB after a successful context
restore during resume. The host controller would fall off the command
ring sometime later, causing it to not respond to new commands.
The link TRB issue has been fixed with commit
158886cd2cf4599e04f9b7e10cb767f5f39b14f1 "xHCI: fix bug in
xhci_clear_command_ring()", so revert the reset-on-resume quirk, as it's
not necessary.
Commit df711fc9962b9491af2b92bd0d21ecbfefe4e5fa was marked for stable
trees back to 2.6.37, but according to my mail, it has not made it into
Linus' tree or the stable trees yet.

When system enters suspend, xHCI driver clears command ring by writing zero
to all the TRBs. However, this also writes zero to the Link TRB, and the ring
is mangled. This may cause driver accesses wrong memory address and the
result is unpredicted.
When clear the command ring, keep the last Link TRB intact, only clear its
cycle bit. This should fix the "command ring full" issue reported by Oliver
Neukum.
This should be backported to stable kernels as old as 2.6.37, since the
commit 89821320 "xhci: Fix command ring replay after resume" is merged.

If a driver wants to do command mode IO while CIO is doing
online path verification we ignore this request and provide
a fake irb when we are done and the driver can do IO again.
For transport mode IO we have no such mechanism, giving the
driver no other chance then to retry the action until we are
done. This is not very reliable.
Provide a fake irb for transport mode IO as well.

When a driver requests to do IO, we will adjust the mask of
paths to be used to exclude varied offline paths.
Drivers trying to do IO solely on paths which are online but some
way defective may lack the information to do proper error handling.
There is no reason to allow the usage of known to be broken paths.
Thus restrict the paths a ccw driver can use for IO to a subset of
the paths cio found usable (this also excludes offline paths).

Use the proper macro to issue the debugging message in
radeon_atif_call(). Otherwise we spam the log of many systems with a
message which looks like an error message of unknown origin, and could
thus confuse the user. Commit dc77de12dde95c8da39e4c417eb70c7d445cf84b
was a first step in this direction, but was not sufficient IMHO.

Coinciding with stack trace is the following message:
ib0: ib_address_create failed
The code below in ipoib_mcast_join_finish() will note the above
failure in the address handle but otherwise continue:
ah = ipoib_create_ah(dev, priv->pd, &av);
if (!ah) {
ipoib_warn(priv, "ib_address_create failed\n");
} else {
The while loop at the bottom of ipoib_mcast_join_finish() will attempt
to send queued multicast packets in mcast->pkt_queue and eventually
end up in ipoib_mcast_send():
if (!mcast->ah) {
if (skb_queue_len(&mcast->pkt_queue) < IPOIB_MAX_MCAST_QUEUE)
skb_queue_tail(&mcast->pkt_queue, skb);
else {
++dev->stats.tx_dropped;
dev_kfree_skb_any(skb);
}
My read is that the code will requeue the packet and return to the
ipoib_mcast_join_finish() while loop and the stage is set for the
"hung" task diagnostic as the while loop never sees a non-NULL ah, and
will do nothing to resolve.
There are GFP_ATOMIC allocates in the provider routines, so this is
possible and should be dealt with.
The test that induced the failure is associated with a host SM on the
same server during a shutdown.
This patch causes ipoib_mcast_join_finish() to exit with an error
which will flush the queued mcast packets. Nothing is done to unwind
the QP attached state so that subsequent sends from above will retry
the join.

With the revert of "of/irq: of_irq_find_parent: check for parent equal to
child" (dc9372808412edb), we need another way to handle parent node equal
to the child node. This can simply be handled in of_irq_init by checking
for this condition.

The original implementation of dequeuing a request in progress
is not correct. Change to use a correct process and also clean
up the related functions a little bit.

In order to support multiple SoC kernel image, compile-time dependency
on a specific SoC type should be avoided.
fsl_udc_clk_finalize is already protected by cpu_is_mx35(), so remove
the compile-time check for CONFIG_SOC_IMX35.

Fix the following build error:
CC [M] drivers/usb/gadget/fsl_mxc_udc.o
drivers/usb/gadget/fsl_mxc_udc.c: In function 'fsl_udc_clk_finalize':
drivers/usb/gadget/fsl_mxc_udc.c:98: error: implicit declaration of function 'readl'
drivers/usb/gadget/fsl_mxc_udc.c:100: error: implicit declaration of function 'writel'
This error is caused by the follwing commit:
(16fcb63: arm/imx: remove mx31_setup_weimcs( ) from mx31.h)
,which removed '#include <linux/io.h>' from mx31.h.
fsl_mxc_udc.c includes <mach/hardware.h>, which in turns includes mx31.h, so
that's the reason fsl_mxc_udc.c built fine previously.
Instead of relying on the indirect inclusion of the linux/io.h header file,
include it directly in fsl_mxc_udc.c.

Some ISO gadgets, like audio, has SYNC attribute as well as
USB_ENDPOINT_XFER_ISOC for their bmAttributes at ISO endpoint
descriptor. So, it needs to use usb_endpoint_xfer_isoc to judge
ISO XFER.
