Trond Myklebust f39c1bfb5a SUNRPC: Fix a UDP transport regression
Commit 43cedbf0e8 (SUNRPC: Ensure that
we grab the XPRT_LOCK before calling xprt_alloc_slot) is causing
hangs in the case of NFS over UDP mounts.

Since neither the UDP or the RDMA transport mechanism use dynamic slot
allocation, we can skip grabbing the socket lock for those transports.
Add a new rpc_xprt_op to allow switching between the TCP and UDP/RDMA
case.

Note that the NFSv4.1 back channel assigns the slot directly
through rpc_run_bc_task, so we can ignore that case.

Greg Kroah-Hartman 23649aa6f1 usb: fixes for v3.6-rc4
Here's a rather big set of fixes for v3.6-rc4.
 
 There are some fixes for bugs which have been pending for a long
 time and only now were uncovered, like the musb and dwc3 patches.
 
 We have some remaining fixes for the ep->desc patch series from
 Ido, a fix for renesas DMA usage, IRQ check on musb's DMA and
 an oops fix on musb Host implementation.
 
 All patches have been pending on linux-usb for a long time and
 shouldn't cause any further regressions.

The I2S controllers are programmed with an "attention" level of 4 DWORDs.
This must match the configuration passed to the DMA driver, so that when
they burst in data, they don't overflow the available FIFO space. Also,
the burst size is relevant to the destination for playback, and source
for capture, not vice-versa as originally written.

Ming Lei ac39b3ea73 firmware loader: let caching firmware piggyback on loading firmware
After starting caching firmware, there is still some time left
before devices are suspended, during the period, request_firmware
or its nowait version may still be triggered by the below situations
to load firmware images which can't be cached during suspend/resume
cycle.

	- new devices added
	- driver bind
	- or device open kind of things

This patch utilizes the piggyback trick to cache firmware for
this kind of situation: just increase the firmware buf's reference
count and add the fw name entry into cache entry list after starting
caching firmware and before syscore_suspend() is called.

Greg Kroah-Hartman 45f035ab9b CONFIG_HOTPLUG should be always on
CONFIG_HOTPLUG is a very old option, back when we had static systems and it was
odd that any type of device would be removed or added after the system had
started up.  It is quite hard to disable it these days, and even if you do, it
only saves you about 200 bytes.  However, if it is disabled, lots of bugs show
up because it is almost never tested if the option is disabled.

This is a step to eventually just remove the option entirely, which will clean
up all of the devinit* variable and function pointer options, that everyone
(myself include) ends up getting wrong eventually, causing real problems when
memory segments are removed yet we don't expect them to be.

This is a completely different CONFIG_HOTPLUG problem, only
demonstrating another reason why CONFIG_HOTPLUG should go away.  I had a
hard time trying to disable it anyway ;-)

The problem this time is lots of code assuming that a call to
add_uevent_var() will guarantee that env->buflen > 0.  This is not true
if CONFIG_HOTPLUG is unset.  So things like this end up overwriting
env->envp_idx because the array index is -1:

	if (add_uevent_var(env, "MODALIAS="))
		return -ENOMEM;
        len = input_print_modalias(&env->buf[env->buflen - 1],
				   sizeof(env->buf) - env->buflen,
				   dev, 0);

Don't know what the best action is, given that there seem to be a *lot*
of this around the kernel.  This patch "fixes" the problem for me, but I
don't know if it can be considered an appropriate fix.

[ It is the correct fix for now, for 3.7 forcing CONFIG_HOTPLUG to
always be on is the longterm fix, but it's too late for 3.6 and older
kernels to resolve this that way - gregkh ]

Pratyush Anand f4a53c5511 usb: dwc3: gadget: fix pending isoc handling
If xfernotready is received and there is no request in request_list then
REQUEST_PENDING flag must be set, so that next request in ep queue is executed.

In case of isoc transfer, if xfernotready is already elapsed and even first
request has not been queued to request_list, then issue END TRANSFER, so that
you can receive xfernotready again and can have notion of current microframe.

dma_controller_create() in this MUSB DMA driver only regards 0 as a wrong IRQ
number, despite platform_get_irq_byname() that it calls returns -ENXIO in that

naturally fails, the following is printed to the console:

In case of ep0 out, if length is not aligned to maxpacket size then we use
dwc->ep_bounce_addr for dma transfer and not request->dma. Since, we have
alreday done memcpy from dwc->ep0_bounce to request->buf, so we do not need to
issue cache sync function. In fact, cache sync function will bring wrong data
in request->buf from request->dma in this scenario.

So, cache sync function must not be executed in case of ep0 bounced.

Trond Myklebust 1f1ea6c2d9 NFSv4: Fix buffer overflow checking in __nfs4_get_acl_uncached
Pass the checks made by decode_getacl back to __nfs4_get_acl_uncached
so that it knows if the acl has been truncated.

The current overflow checking is broken, resulting in Oopses on
user-triggered nfs4_getfacl calls, and is opaque to the point
where several attempts at fixing it have failed.
This patch tries to clean up the code in addition to fixing the
Oopses by ensuring that the overflow checks are performed in
a single place (decode_getacl). If the overflow check failed,
we will still be able to report the acl length, but at least
we will no longer attempt to cache the acl or copy the
truncated contents to user space.

Takashi Iwai 1213a205f9 ALSA: usb-audio: Fix bogus error messages for delay accounting
The recent fix for the missing fine delayed time adjustment gives
strange error messages at each start of the playback stream, such as
  delay: estimated 0, actual 352
  delay: estimated 353, actual 705

These come from the sanity check in retire_playback_urb().  Before the
stream is activated via start_endpoints(), a few silent packets have
been already sent.  And at this point the delay account is still in
the state as if the new packets are just queued, so the driver gets
confused and spews the bogus error messages.

For fixing the issue, we just need to check whether the received
packet is valid, whether it's zero sized or not.

Dylan Reid 57b2d68863 ASoC: samsung dma - Don't indicate support for pause/resume.
The pause and resume operations indicate that the stream can be
un-paused/resumed from the exact location they were paused/suspended.
This is not true for this driver, the pause and suspend triggers share
the same code path with stop, they flush all pending DMA transfers.
This drops all pending samples.  The pause_release/resume triggers are
the same as start, except that prepare won't be called beforehand,
nothing will be enqueued to the DMA engine and nothing will happen (no
audio).  Removing the pause flag will let apps know that it isn't
supported.  Removing the resume flag will cause user space to call
prepare and start instead of resume, so audio will continue playing when
the system wakes up.

Before removing the pause and resume flags, I tested this on an exynos
5250, using 'aplay -i'. Pause/un-pause leads to silence followed by a
write error.  Suspend/resume testing led to the same result.  Removing
the two flags fixes suspend/resume (since snd_pcm_prepare is called
again). And leads to a proper reporting of pause not supported.
