2012-09-07net/mlx4_core: Looking for promiscuous entries on the correct portAviad Yehezkel
The search for promisc entries was always done on the first port, While the addition is done on the correct port. This lead to resource leackage of promisc entries on the second port and brought to a state where we could no longer enter to promiscuous mode after enough iterations of "ifconfig promisc" on the second port. Fix that by using the correct port when searching.

2012-09-07SUNRPC: Fix a UDP transport regressionTrond Myklebust
Commit 43cedbf0e8dfb9c5610eb7985d5f21263e313802 (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.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into work-linus 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.

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.

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.

2012-09-06ALSA: usb-audio: Fix bogus error messages for delay accountingTakashi Iwai
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.

2012-09-06ASoC: samsung dma - Don't indicate support for pause/resume.Dylan Reid
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.

2012-09-06s390/cio: invalidate cdev pointer before deregistrationSebastian Ott
Make sure that the cdev pointer for IO subchannels is set to NULL when we deregister the device (and release its last reference). This will fix a bug were another process operates on an already freed ccw device.

2012-09-06s390/cio: fix IO subchannel event raceSebastian Ott
If the subchannel event function is called from IRQ context and we observe that the subchannel in question is gone we flag the attached device as not operational and schedule the event function to be called again from process context where the subchannel gets deregistered. However if the subchannel reappeared at the time the event function gets called from process context we would do nothing and leave the device in not operational state. Recognize this case in sch_get_action and trigger reexamination of the subchannel/device.

2012-09-06s390/dasd: move wake_up callSebastian Ott
Ensure that all work is done when the process waiting for a dasd state change is woken up. With this change it is save to assume that after a userspace triggered state change and a udev settle invocation there are no unexpected users of a dasd device.

2012-09-06s390/hugetlb: use direct TLB flushing for hugetlbfs pagesGerald Schaefer
huge_ptep_get_and_clear() is either missing a TLB invalidation or an mm->context.attach_count check. Since the attach_count logic was introduced with normal ptes in mind, let's just use direct TLB flushing for hugetlbfs pages.

2012-09-06ALSA: hda - Fix missing Master volume for STAC9200/925xTakashi Iwai
With the commit [2faa3bf: ALSA: hda - Rewrite the mute-LED hook with vmaster hook in patch_sigmatel.c], the former Master volume control was converted to PCM. This was supposed to be covered by the vmaster control. But due to the lack of "PCM" slave definition, this didn't happen properly. The patch fixes the missing entry.
