2012-10-02ALSA: hda - Workaround for silent output on VAIO Z with ALC889Takashi Iwai
commit e427c2375646789ecd0ccaef1a1e41458559ab2d upstream. On recent kernels, Realtek codec parser tries to optimize the routing aggressively and take the headphone output as primary at first. This caused a regression on VAIO Z with ALC889, the silent output from the speaker. The problem seems that the speaker pin must be connected to the first DAC (0x02) on this machine by some reason although the codec itself advertises the flexible routing with any DACs. This patch adds a fix-up for choosing the speaker pin as the primary so that the right DAC is assigned on this device.

commit 9d8dad742ad1c74d7e7210ee05d0b44961d5ea16 upstream. The higher ptrace restriction levels should be blocking even PTRACE_TRACEME requests. The comments in the LSM documentation are misleading about when the checks happen (the parent does not go through security_ptrace_access_check() on a PTRACE_TRACEME call).

2012-06-25stable: Allow merging of backports for serious user-visible performance issuesMel Gorman
Distribution kernel maintainers routinely backport fixes for users that were deemed important but not "something critical" as defined by the rules. To users of these kernels they are very serious and failing to fix them reduces the value of -stable. The problem is that the patches fixing these issues are often subtle and prone to regressions in other ways and need greater care and attention. To combat this, these "serious" backports should have a higher barrier to entry. This patch relaxes the rules to allow a distribution maintainer to merge to -stable a backported patch or small series that fixes a "serious" user-visible performance issue. They should include additional information on the user-visible bug affected and a link to the bugzilla entry if available. The same rules about the patch being already in mainline still apply.

2012-06-11[media] bw-qcam: driver and pixfmt documentation fixesHans Verkuil
Fix the documentation of the Y4 and Y6 formats. Fix a poll() issue, add support for enum_frmsizes, set the proper parent device and fix a few compliance issues. Tested with an actual Connectix B&W parallel port webcam, both on a little-endian and a big-endian platform. This driver has never been so good, doing 320x240 at 1 frame per second :-) I know, nobody cares, but still it is cool that linux can still support this old webcam.

git://git.pengutronix.de/git/wsa/linux Pull embedded i2c update from Wolfram Sang: "This only contains one new driver which had multiple dependencies (pinctrl, i2c-mux-rework, new devm_* functions), so I decided to wait for rc1. Plus, it had to wait a little for the ack of a devicetree maintainer since the bindings were not trivial enough for me to pass through. So, given that, I hope there is still something like the "new driver rule", so we could have the driver in 3.5 and people can start using it. That would make merging support for some boards easier for 3.6 since the dependency on this driver is gone then." * 'i2c-embedded/for-current' of git://git.pengutronix.de/git/wsa/linux: i2c: Add generic I2C multiplexer using pinctrl API

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/mm Pull frontswap feature from Konrad Rzeszutek Wilk: "Frontswap provides a "transcendent memory" interface for swap pages. In some environments, dramatic performance savings may be obtained because swapped pages are saved in RAM (or a RAM-like device) instead of a swap disk. This tag provides the basic infrastructure along with some changes to the existing backends." Fix up trivial conflict in mm/Makefile due to removal of swap token code changing a line next to the new frontswap entry. This pull request came in before the merge window even opened, it got delayed to after the merge window by me just wanting to make sure it had actual users. Apparently IBM is using this on their embedded side, and Jan Beulich says that it's already made available for SLES and OpenSUSE users. Also acked by Rik van Riel, and Konrad points to other people liking it too. So in it goes.

2012-06-03dm thin: provide userspace access to pool metadataJoe Thornber
This patch implements two new messages that can be sent to the thin pool target allowing it to take a snapshot of the _metadata_. This, read-only snapshot can be accessed by userland, concurrently with the live target. Only one metadata snapshot can be held at a time. The pool's status line will give the block location for the current msnap. Since version 0.1.5 of the userland thin provisioning tools, the thin_dump program displays the msnap as follows: thin_dump -m <msnap root> <metadata dev> Available here: https://github.com/jthornber/thin-provisioning-tools Now that userland can access the metadata we can do various things that have traditionally been kernel side tasks: i) Incremental backups. By using metadata snapshots we can work out what blocks have changed over time. Combined with data snapshots we can ensure the data doesn't change while we back it up. A short proof of concept script can be found here: https://github.com/jthornber/thinp-test-suite/blob/master/incremental_backup_example.rb ii) Migration of thin devices from one pool to another. iii) Merging snapshots back into an external origin. iv) Asyncronous replication.
