2014-03-26s390/con3270: optionally disable auto updateMartin Schwidefsky
This patch adds a parameter 'auto_update' to the con3270 driver, causing the 'auto_update' feature to be disabled if unset. The 'auto_update' feature will cause the con3270 driver to switch to the console view whenever new system messages are displayed, which makes working on the 3270 terminal awkward.

2014-03-25Revert "sysfs, driver-core: remove unused ↵Greg Kroah-Hartman
{sysfs|device}_schedule_callback_owner()" This reverts commit d1ba277e79889085a2faec3b68b91ce89c63f888. As reported by Stephen, this patch breaks linux-next as a ppc patch suddenly (after 2 years) started using this old api call. So revert it for now, it will go away in 3.15-rc2 when we can change the PPC call to the new api.

2014-03-25tracing: Fix traceon trigger condition to actually turn tracing onSteven Rostedt (Red Hat)
While working on my tutorial for 2014 Linux Collaboration Summit I found that the traceon trigger did not work when conditions were used. The other triggers worked fine though. Looking into it, it is because of the way the triggers use the ring buffer to store the fields it will use for the condition. But if tracing is off, nothing is stored in the buffer, and the tracepoint exits before calling the trigger to test the condition. This is fine for all the triggers that only work when tracing is on, but for traceon trigger that is to work when tracing is off, nothing happens. The fix is simple, just use a temp ring buffer to record the event if tracing is off and the event has a trace event conditional trigger enabled. The rest of the tracepoint code will work just fine, but the tracepoint wont be recorded in the other buffers.

2014-03-25fs: remove now stale label in anon_inode_init()Linus Torvalds

2014-03-25fs: Avoid userspace mounting anon_inodefs filesystemJan Kara
anon_inodefs filesystem is a kernel internal filesystem userspace shouldn't mess with. Remove registration of it so userspace cannot even try to mount it (which would fail anyway because the filesystem is MS_NOUSER). This fixes an oops triggered by trinity when it tried mounting anon_inodefs which overwrote anon_inode_inode pointer while other CPU has been in anon_inode_getfile() between ihold() and d_instantiate(). Thus effectively creating dentry pointing to an inode without holding a reference to it.

ASoC: Updates for v3.15 Quite a busy release for ASoC this time, more on janitorial work than exciting new features but welcome nontheless: - Lots of cleanups from Takashi for enumerations; the original API for these was error prone so he's refactored lots of code to use more modern APIs which avoid issues. - Elimination of the ASoC level wrappers for I2C and SPI moving us closer to converting to regmap completely and avoiding some randconfig hassle. - Provide both manually and transparently locked DAPM APIs rather than a mix of the two fixing some concurrency issues. - Start converting CODEC drivers to use separate bus interface drivers rather than having them all in one file helping avoid dependency issues. - DPCM support for Intel Haswell and Bay Trail platforms. - Lots of work on improvements for simple-card, DaVinci and the Renesas rcar drivers. - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the CSR SiRF SoC. # gpg: Signature made Wed 12 Mar 2014 23:05:45 GMT using RSA key ID 7EA229BD # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" # gpg: aka "Mark Brown <broonie@debian.org>" # gpg: aka "Mark Brown <broonie@kernel.org>" # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" # gpg: aka "Mark Brown <broonie@linaro.org>" # gpg: aka "Mark Brown <Mark.Brown@linaro.org>"

2014-03-25ASoC: Remove name_prefix unset during DAI link init hackLars-Peter Clausen
Before we had card level support for DAPM and controls machine drivers would register their controls and DAPM elements with the CODEC. This required us to temporarily unset the name_prefix of a CODEC during the rtd init callback to avoid the machine level controls getting the CODEC's prefix. Now that all machine drivers properly register their machine level controls and DAPM elements with the card rather than with the CODEC we can drop the hack that sets the CODEC's name_prefix to NULL while calling the DAI link or AUX dev init callback.
