2013-09-03fuse: postpone end_page_writeback() in fuse_writepage_locked()Maxim Patlasov
The patch fixes a race between ftruncate(2), mmap-ed write and write(2): 1) An user makes a page dirty via mmap-ed write. 2) The user performs shrinking truncate(2) intended to purge the page. 3) Before fuse_do_setattr calls truncate_pagecache, the page goes to writeback. fuse_writepage_locked fills FUSE_WRITE request and releases the original page by end_page_writeback. 4) fuse_do_setattr() completes and successfully returns. Since now, i_mutex is free. 5) Ordinary write(2) extends i_size back to cover the page. Note that fuse_send_write_pages do wait for fuse writeback, but for another page->index. 6) fuse_writepage_locked proceeds by queueing FUSE_WRITE request. fuse_send_writepage is supposed to crop inarg->size of the request, but it doesn't because i_size has already been extended back. Moving end_page_writeback to the end of fuse_writepage_locked fixes the race because now the fact that truncate_pagecache is successfully returned infers that fuse_writepage_locked has already called end_page_writeback. And this, in turn, infers that fuse_flush_writepages has already called fuse_send_writepage, and the latter used valid (shrunk) i_size. write(2) could not extend it because of i_mutex held by ftruncate(2).

2013-09-03pwm: pxa: Use module_platform_driverMike Dunn
Commit 76abbdde2d95a3807d0dc6bf9f84d03d0dbd4f3d pwm: Add sysfs interface causes a kernel oops due to a null pointer dereference on PXA platforms. This happens because the class added by the patch is registered in a subsys_initcall (initcall4), but the pxa pwm driver is registered in arch_initcall (initcall3). If the class is not registered before the driver probe function runs, the oops occurs in device_add() when the uninitialized pointers in struct class are dereferenced. I don't see a reason that the driver must be an arch_initcall, so this patch makes it a regular module_platform_driver (initcall6), preventing the oops.

2013-09-03drm/i915: fix lvds/dp panel fitter settingImre Deak
If need to enable the panel fitter, the crtc timings have to be programmed according to the panel's native (fixed) mode. This isn't the case atm, since after the encoder changes adjusted_mode to fixed mode the crtc_* timing fields of adjusted_mode will stay at their original non-native values that the user passed in. This results in a corrupted output. One exception is when we have a second pass of computing encoder configs due to bandwidth limitation, since then we'll set adjusted_mode.crtc_* fields to the fixed mode values set in the first pass; so in this case things will work out. Fix this by updating the adjusted_mode.crtc_* fields when we set the fixed panel mode.

2013-09-03drm/i915: Don't mask EI UP interrupt on IVB|SNBMika Kuoppala
Submitting a batchbuffer which simulates a gpu hang by doing MI_BATCH_BUFFER_START into itself, to test hangcheck, started to hard hang the whole box (IVB).

HSW doesn't hang with EI UP masked.

2013-09-03module: Fix mod->mkobj.kobj potentially freed too earlyLi Zhong
DEBUG_KOBJECT_RELEASE helps to find the issue attached below. After some investigation, it seems the reason is: The mod->mkobj.kobj(ffffffffa01600d0 below) is freed together with mod itself in free_module(). However, its children still hold references to it, as the delay caused by DEBUG_KOBJECT_RELEASE. So when the child(holders below) tries to decrease the reference count to its parent in kobject_del(), BUG happens as it tries to access already freed memory. This patch tries to fix it by waiting for the mod->mkobj.kobj to be really released in the module removing process (and some error code paths).

2013-09-03ALSA: hda - Re-setup HDMI pin and audio infoframe on stream switchesTakashi Iwai
When the transcoder:port mapping on Haswell HDMI/DP audio is changed during the stream playback, the sound gets lost. Typically this problem is seen when the user switches the graphics mode from eDP+DP to DP-only configuration, where CRTC 1 is used for DP in the former while CRTC 0 is used for the latter. The graphics controller notifies the change via the normal ELD update procedure, so we get the intrinsic event. For enabling the sound again, the HDMI audio driver needs to reset the pin and set up the audio infoframe again. This patch achieves it by: - keep the current status of channels and info frame setup in per_pin struct, - check the reconnection in the intrinsic event handler, - reset the pin and the re-invoke hdmi_setup_audio_infoframe() accordingly. The hdmi_setup_audio_infoframe() function has been changed, too, so that it can be invoked without passing the substream instance. The patch is mostly based on the work by Mengdong Lin.

This is for use by Frederic Weisbecker's adaptive-ticks mechanism. Its purpose is to allow the timekeeping CPU to shut off its tick when all other CPUs are idle.

2013-09-03f2fs: avoid an overflow during utilization calculationJaegeuk Kim
The current f2fs uses all the block counts with 32 bit numbers, which is able to cover about 15TB volume. But in calculation of utilization, f2fs multiplies the count by 100 which can induce overflow. This patch fixes this. Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>
2013-09-02IB/iser: Fix redundant pointer check in dealloc flowSagi Grimberg
This bug was discovered by Smatch static checker run by Dan Carpenter. If in free_rx_descriptors(), rx_descs are not NULL then the iser device is definately not NULL, so no need to check it before dereferencing it.

2013-09-02RDMA/ocrdma: Dont use PD 0 for userpace CQ DBNaresh Gottumukkala
Create_CQ verb doesn't provide a PD pointer. So, until now we are creating all (both userspace and kernel) CQ DB regions from PD0. This will result in mmapping PD0 to applications. A rogue userspace application can mess things up. Also more serious issues is even the be2net NIC uses PD0. This patch addresses this problem by: 1) Create a PD page for every userspace application when the alloc_ucontext is called. This will be destroyed in dealloc_ucontext. 2) All CQs for that context will use the PD allocated in ucontext. 3) The first create_PD call from application will result in returning the PD address from its ucontext (no new PD will be created). 4) For subsecquent create_pd calls from application, we create new PDs for the application.
