2013-06-03drm/i915: optimize vblank waits in set_base_atomicDaniel Vetter
We only need to do them if the pipe is actually running and if the framebuffers have changed. Removes two "wait for vblank timed out" messages when doing a suspend/resume cycle on my i855gm. v2: s/to_intel_ctrc(crtc)/intel_crtc/ spotted by Chris.

2013-06-03ALSA: hda/via - Fix wrongly cleared pins after suspend on VT1802Takashi Iwai
VIA driver has a special suspend handling only for VT1802 to reduce the pop noise. During the transition to the generic parser, the behavior of snd_hda_set_pin_ctl() was also changed to modify the cached values, too. And this caused a regression where the pin is still cleared even after the resume (including the resume from power save), resulting in the silent output. The fix is simply to replace snd_hda_set_pin_ctl() with the explicit call of snd_hda_codec_write() again.

2013-06-03ALSA: hda - Allow setting automute/automic hooks after parsingTakashi Iwai
Some codec drivers (VIA codecs and some Realtek fixups) set the automute and automic hooks after calling snd_hda_gen_parse_auto_config(). In the current code, the hook pointers are referred only in snd_hda_gen_parse_auto_config() and passed to snd_hda_jack_detect_enable_callback(), thus changing the hook values won't change the actually called callbacks properly. This patch fixes this bug by setting the static functions as the primary callback functions for the jack detection, and let them calling the appropriate hooks dynamically.

2013-06-03ALSA: hda/via - Disable broken dynamic power controlTakashi Iwai

This results in the wrong power setup in the end. As a temporary workaround, we need to disable the calls together with the non-functional dynamic power control enum.

2013-06-03drm: fix a use-after-free when GPU acceleration disabledHuacai Chen
When GPU acceleration is disabled, drm_vblank_cleanup() will free the vblank-related data, such as vblank_refcount, vblank_inmodeset, etc. But we found that drm_vblank_post_modeset() may be called after the cleanup, which use vblank_refcount and vblank_inmodeset. And this will cause a kernel panic. Fix this by return immediately if dev->num_crtcs is zero. This is the same thing that drm_vblank_pre_modeset() does.

2013-06-03drm/i915: detect hang using per ring hangcheck_scoreMika Kuoppala
Keep track of ring seqno progress and if there are no progress detected, declare hang. Use actual head (acthd) to distinguish between ring stuck and batchbuffer looping situation. Stuck ring will be kicked to trigger progress. This commit adds a hard limit for batchbuffer completion time. If batchbuffer completion time is more than 4.5 seconds, the gpu will be declared hung. Review comment from Ben which nicely clarifies the semantic change: "Maybe I'm just stating the functional changes of the patch, but in case they were unintended here is what I see as potential issues: 1. "If ring B is waiting on ring A via semaphore, and ring A is making progress, albeit slowly - the hangcheck will fire. The check will determine that A is moving, however ring B will appear hung because the ACTHD doesn't move. I honestly can't say if that's actually a realistic problem to hit it probably implies the timeout value is too low. 2. "There's also another corner case on the kick. If the seqno = 2 (though not stuck), and on the 3rd hangcheck, the ring is stuck, and we try to kick it... we don't actually try to find out if the kick helped" v2: use atchd to detect stuck ring from loop (Ben Widawsky) v3: Use acthd to check when ring needs kicking.

2013-06-02net: force a reload of first item in hlist_nulls_for_each_entry_rcuEric Dumazet
Roman Gushchin discovered that udp4_lib_lookup2() was not reloading first item in the rcu protected list, in case the loop was restarted. This produced soft lockups as in https://lkml.org/lkml/2013/4/16/37 rcu_dereference(X)/ACCESS_ONCE(X) seem to not work as intended if X is ptr->field : In some cases, gcc caches the value or ptr->field in a register. Use a barrier() to disallow such caching, as documented in Documentation/atomic_ops.txt line 114 Thanks a lot to Roman for providing analysis and numerous patches.
