git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v3.20 merge window Here's the big pull request for Gadgets and PHYs. It's a total of 217 non-merge commits with pretty much everything being touched. The most important bits are a ton of new documentation for almost all usb gadget functions, a new isp1760 UDC driver, several improvements to the old net2280 UDC driver, and some minor tracepoint improvements to dwc3. Other than that, a big list of minor cleanups, smaller bugfixes and new features all over the place. Signed-off-by: Felipe Balbi <balbi@ti.com>

2015-02-04block: Simplify bsg complete allPeter Zijlstra
It took me a few tries to figure out what this code did; lets rewrite it into a more regular form. The thing that makes this one 'special' is the BSG_F_BLOCK flag, if that is not set we're not supposed/allowed to block and should spin wait for completion. The (new) io_wait_event() will never see a false condition in case of the spinning and we will therefore not block.

2015-02-04NFSv4.1: Ask for no delegation on OPEN if using O_DIRECTTrond Myklebust
If we're using NFSv4.1, then we have the ability to let the server know whether or not we believe that returning a delegation as part of our OPEN request would be useful. The feature needs to be used with care, since the client sending the request doesn't necessarily know how other clients are using that file, and how they may be affected by the delegation. For this reason, our initial use of the feature will be to let the server know when the client believes that handing out a delegation would not be useful. The first application for this function is when opening the file using O_DIRECT. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

2015-02-04drm: remove DRM_FORMAT_NV12MTDaniel Vetter
So this has been merged originally in commit 83052d4d5cd518332440bb4ee63d68bb5f744e0f Author: Seung-Woo Kim <sw0312.kim@samsung.com> Date: Thu Dec 15 15:40:55 2011 +0900 drm: Add multi buffer plane pixel formats which hasn't seen a lot of review really. The problem is that it's not a real pixel format, but just a different way to lay out NV12 pixels in macroblocks, i.e. a tiling format. The new way of doing this is with the soon-to-be-merged fb modifiers. This was brough up in some long irc discussion around the entire topic, as an example of where things have gone wrong. Luckily we can correct the mistake: - The kms side support for NV12MT is all dead code because format_check in drm_crtc.c never accepted NV12MT. - The gem side for the gsc support doesn't look better: The code forgets to set the pixel format and makes a big mess with the tiling mode bits, inadvertedly setting them all. Conclusion: This never really worked (at least not in upstream) and hence we can safely correct our mistake here.

2015-02-04perf: Decouple unthrottling and rotatingMark Rutland
Currently the adjusments made as part of perf_event_task_tick() use the percpu rotation lists to iterate over any active PMU contexts, but these are not used by the context rotation code, having been replaced by separate (per-context) hrtimer callbacks. However, some manipulation of the rotation lists (i.e. removal of contexts) has remained in perf_rotate_context(). This leads to the following issues: * Contexts are not always removed from the rotation lists. Removal of PMUs which have been placed in rotation lists, but have not been removed by a hrtimer callback can result in corruption of the rotation lists (when memory backing the context is freed). This has been observed to result in hangs when PMU drivers built as modules are inserted and removed around the creation of events for said PMUs. * Contexts which do not require rotation may be removed from the rotation lists as a result of a hrtimer, and will not be considered by the unthrottling code in perf_event_task_tick. This patch fixes the issue by updating the rotation ist when events are scheduled in/out, ensuring that each rotation list stays in sync with the HW state. As each event holds a refcount on the module of its PMU, this ensures that when a PMU module is unloaded none of its CPU contexts can be in a rotation list. By maintaining a list of perf_event_contexts rather than perf_event_cpu_contexts, we don't need separate paths to handle the cpu and task contexts, which also makes the code a little simpler. As the rotation_list variables are not used for rotation, these are renamed to active_ctx_list, which better matches their current function. perf_pmu_rotate_{start,stop} are renamed to perf_pmu_ctx_{activate,deactivate}.

2015-02-03ipv6: Select fragment id during UFO segmentation if not set.Vlad Yasevich
If the IPv6 fragment id has not been set and we perform fragmentation due to UFO, select a new fragment id. We now consider a fragment id of 0 as unset and if id selection process returns 0 (after all the pertrubations), we set it to 0x80000000, thus giving us ample space not to create collisions with the next packet we may have to fragment. When doing UFO integrity checking, we also select the fragment id if it has not be set yet. This is stored into the skb_shinfo() thus allowing UFO to function correclty. This patch also removes duplicate fragment id generation code and moves ipv6_select_ident() into the header as it may be used during GSO.

2015-02-04ip: convert tcp_sendmsg() to iov_iter primitivesAl Viro
patch is actually smaller than it seems to be - most of it is unindenting the inner loop body in tcp_sendmsg() itself... the bit in tcp_input.c is going to get reverted very soon - that's what memcpy_from_msg() will become, but not in this commit; let's keep it reasonably contained... There's one potentially subtle change here: in case of short copy from userland, mainline tcp_send_syn_data() discards the skb it has allocated and falls back to normal path, where we'll send as much as possible after rereading the same data again. This patch trims SYN+data skb instead - that way we don't need to copy from the same place twice. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2015-02-03i2o: move to stagingAlan Cox
The I2O layer deals with a technology that to say the least didn't catch on in the market. The only relevant products are some of the AMI MegaRAID - which supported I2O and its native mode (The native mode is faster and runs on Linux), an obscure crypto ethernet card that's now so many years out of date nobody would use it, the old DPT controllers, which speak their own dialect and have their own driver - and ermm.. thats about it. We also know the code isn't in good shape as recently a patch was proposed and queried as buggy, which in turn showed the existing code was broken already by prior "clean up" and nobody had noticed that either. It's coding style robot code nothing more. Like some forgotten corridor cleaned relentlessly by a lost Roomba but where no user has trodden in years. Move it to staging and then to /dev/null.

2015-02-03ti-st: clean up data types (fix harmless memory corruption)Dan Carpenter
The big issue here is: of_property_read_u32(np, "flow_cntrl", (u32 *)&dt_pdata->flow_cntrl); "->flow_cntrl" is a char so when we write a 32 bit number to it then it corrupts past the end of the char. It's probably hard to notice because the struct has padding so the code works on little endian systems. But on a big endian system the code would fail and on a 64 bit, big endian systems then "nshutdown_gpio" and "baud_rate" would be buggy as well.

2015-02-03PM / Domains: Eliminate the mutex for the generic_pm_domain_dataUlf Hansson
While adding devices to their PM domains, dev_pm_qos_add_notifier() was invoked while allocating the generic_pm_domain_data for the device. Since the generic_pm_domain_data's device pointer will be assigned after allocation, the ->genpd_dev_pm_qos_notifier() callback could be called prior having a valid pointer to the device. Similar scenario existed while removing a device from a genpd. To cope with these scenarios a mutex was used to protect the pointer to the device. By re-order the sequence for when dev_pm_qos_add|remove_notifier() are invoked, we make sure the ->genpd_dev_pm_qos_notifier() callback are always called with a valid device pointer available. In this way, we eliminate the need for protecting the pointer and thus we can remove the mutex from the struct generic_pm_domain_data.
