Pull sound fixes from Takashi Iwai: "The only bulk changes in this request is ABI updates for ASoC topology API. It's a new API that was introduced in 4.2, and we'd like to avoid ABI change after the release, so it's taken now. As there is no real in-tree user for this API, it should be fairly safe. Other than that, the usual small fixes are found in various drivers: ASoC cs4265, rt5645, intel-sst, firewire, oxygen and HD-audio" * tag 'sound-4.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ASoC: topology: Add private data type and bump ABI version to 3 ASoC: topology: Add ops support to byte controls UAPI ASoC: topology: Update TLV support so we can support more TLV types ASoC: topology: add private data to manifest ASoC: topology: Add subsequence in topology ALSA: hda - one Dell machine needs the headphone white noise fixup ALSA: fireworks/firewire-lib: add support for recent firmware quirk Revert "ALSA: fireworks: add support for AudioFire2 quirk" ASoC: topology: fix typo in soc_tplg_kcontrol_bind_io() ALSA: HDA: Dont check return for snd_hdac_chip_readl ALSA: HDA: Fix stream assignment for host in decoupled mode ASoC: rt5645: Fix lost pin setting for DMIC1 ALSA: oxygen: Fix logical-not-parentheses warning ASoC: Intel: sst_byt: fix initialize 'NULL device *' issue ASoC: Intel: haswell: fix initialize 'NULL device *' issue ASoC: cs4265: Fix setting dai format for Left/Right Justified

drm/vblank: Use u32 consistently for vblank counters

2015-08-07T12:35:53+00:00

In commit 99264a61dfcda41d86d0960cf2d4c0fc2758a773 Author: Daniel Vetter Date: Wed Apr 15 19:34:43 2015 +0200 drm/vblank: Fixup and document timestamp update/read barriers I've switched vblank->count from atomic_t to unsigned long and accidentally created an integer comparison bug in drm_vblank_count_and_time since vblanke->count might overflow the u32 local copy and hence the retry loop never succeed. Fix this by consistently using u32. Cc: Michel Dänzer Reported-by: Michel Dänzer Reviewed-by: Thierry Reding Signed-off-by: Daniel Vetter

mm: check __PG_HWPOISON separately from PAGE_FLAGS_CHECK_AT_*

2015-08-07T01:39:42+00:00

The race condition addressed in commit add05cecef80 ("mm: soft-offline: don't free target page in successful page migration") was not closed completely, because that can happen not only for soft-offline, but also for hard-offline. Consider that a slab page is about to be freed into buddy pool, and then an uncorrected memory error hits the page just after entering __free_one_page(), then VM_BUG_ON_PAGE(page->flags & PAGE_FLAGS_CHECK_AT_PREP) is triggered, despite the fact that it's not necessary because the data on the affected page is not consumed. To solve it, this patch drops __PG_HWPOISON from page flag checks at allocation/free time. I think it's justified because __PG_HWPOISON flags is defined to prevent the page from being reused, and setting it outside the page's alloc-free cycle is a designed behavior (not a bug.) For recent months, I was annoyed about BUG_ON when soft-offlined page remains on lru cache list for a while, which is avoided by calling put_page() instead of putback_lru_page() in page migration's success path. This means that this patch reverts a major change from commit add05cecef80 about the new refcounting rule of soft-offlined pages, so "reuse window" revives. This will be closed by a subsequent patch.

fs, file table: reinit files_stat.max_files after deferred memory initialisation

2015-08-07T01:39:40+00:00

Dave Hansen reported the following; My laptop has been behaving strangely with 4.2-rc2. Once I log in to my X session, I start getting all kinds of strange errors from applications and see this in my dmesg: VFS: file-max limit 8192 reached The problem is that the file-max is calculated before memory is fully initialised and miscalculates how much memory the kernel is using. This patch recalculates file-max after deferred memory initialisation. Note that using memory hotplug infrastructure would not have avoided this problem as the value is not recalculated after memory hot-add. 4.1: files_stat.max_files = 6582781 4.2-rc2: files_stat.max_files = 8192 4.2-rc2 patched: files_stat.max_files = 6562467 Small differences with the patch applied and 4.1 but not enough to matter.

ASoC: topology: Update TLV support so we can support more TLV types

2015-08-06T11:34:46+00:00

Currently the TLV topology structure is targeted at only supporting the DB scale data. This patch extends support for the other TLV types so they can be easily added at a later stage. TLV structure is moved to common topology control header since it's a common field for controls and can be processed in a general way. Users must set a proper access flag for a control since it's used to decide if the TLV field is valid and if a TLV callback is needed. Removed the following fields from topology TLV struct: - size/count: type can decide the size. - numid: not needed to initialize TLV for kcontrol. - data: replaced by the type specific struct. Added TLV structure to generic control header and removed TLV structure from mixer control. Signed-off-by: Mengdong Lin Signed-off-by: Liam Girdwood Signed-off-by: Mark Brown
