2012-06-18NFSv4.1: Fix umount when filelayout DS is also the MDSTrond Myklebust
Currently there is a 'chicken and egg' issue when the DS is also the mounted MDS. The nfs_match_client() reference from nfs4_set_ds_client bumps the cl_count, the nfs_client is not freed at umount, and nfs4_deviceid_purge_client is not called to dereference the MDS usage of a deviceid which holds a reference to the DS nfs_client. The result is the umount program returns, but the nfs_client is not freed, and the cl_session hearbeat continues. The MDS (and all other nfs mounts) lose their last nfs_client reference in nfs_free_server when the last nfs_server (fsid) is umounted. The file layout DS lose their last nfs_client reference in destroy_ds when the last deviceid referencing the data server is put and destroy_ds is called. This is triggered by a call to nfs4_deviceid_purge_client which removes references to a pNFS deviceid used by an MDS mount. The fix is to track how many pnfs enabled filesystems are mounted from this server, and then to purge the device id cache once that count reaches zero.

2012-06-18[media] Revert "[media] media: mx2_camera: Fix mbus format handling"Guennadi Liakhovetski
This reverts commit d509835e32bd761a2b7b446034a273da568e5573. That commit breaks support for the generic pass-through mode in the driver for formats, not natively supported by it. Besides due to a merge conflict it also breaks driver compilation: drivers/media/video/mx2_camera.c: In function 'mx2_camera_set_bus_param': drivers/media/video/mx2_camera.c:937: error: 'pixfmt' undeclared (first use in this function) drivers/media/video/mx2_camera.c:937: error: (Each undeclared identifier is reported only once drivers/media/video/mx2_camera.c:937: error: for each function it appears in.)

2012-06-18perf/tool: Add support to reuse event grammar to parse out termsJiri Olsa
We want to reuse the event grammar for parsing aliased terms. The obvious reason is we dont need to add new code when there's already support for this in event grammar. Doing this by adding terms and event start entries into event parse grammar. The grammar forks on the begining based on the starting token, which is supplied via bison interface into the lexer. The lexer then returns the starting token as the first token, thus making the grammar switch accordingly. Currently 2 starting tokens/grammars are supported: PE_START_TERMS, PE_START_EVENTS The PE_START_TERMS related grammar uses 'event_config' part of the grammar for term parsing.

2012-06-18perf: Use css_tryget() to avoid propping up css refcountSalman Qazi
An rmdir pushes css's ref count to zero. However, if the associated directory is open at the time, the dentry ref count is non-zero. If the fd for this directory is then passed into perf_event_open, it does a css_get(). This bounces the ref count back up from zero. This is a problem by itself. But what makes it turn into a crash is the fact that we end up doing an extra dput, since we perform a dput when css_put sees the ref count go down to zero. css_tryget() does not fall into that trap. So, we use that instead.

2012-06-18ALSA: hda - Handle open while transitioning to D3.Dylan Reid
This addresses an issue encountered when a pcm is opened while transitioning to low power state (codec->power_on == 1 && codec->power_transition == -1). Add snd_pcm_power_up_d3wait to hda_codec. This function is used to power up from azx_open as opposed to snd_hda_power_up used from codec_exec_verb. When powering up from azx_open, wait for pending power downs to complete, avoiding the power up continuing in parallel with the power down on the work queue. The specific issue seen was with the CS4210 codec, it powers off the ADC and DAC nid in its suspend handler. If it is re-opened before the ~100ms power down process completes, the ADC and DAC nid are initialized while powered down and audio is lost until another suspend/resume cycle.

2012-06-17ixgbe: Fix PHC loophole allowing misconfiguration of increment registerJacob Keller
This patch fixes a potential hole when configuring the cycle counter used to generate the nanosecond time clock. This clock is based off of the SYSTIME registers along with the TIMINCA registers. The TIMINCA register determines the increment to be added to the SYSTIME registers every DMA clock tick. This register needs to be reconfigured whenever the link-speed changes. However, the value calculated stays the same when link is down and when link is up. Misconfiguration can occur if the link status changes due to a reset, which causes the TIMINCA register to be reset. This reset puts the device in an unstable state where the SYSTIME registers stop incrementing and the PTP protocol does not function. The solution is to double check the TIMINCA value and always reset the value if the register is zero. This prevents a misconfiguration bug that halts the PHC.

2012-06-17ARM: 7427/1: mmc: mmci: Defer probe() in case of yet uninitialized GPIOsRoland Stigge
If the GPIOs used by the MMCI driver are not registered yet when the driver is probe()d, they can't be used. This happens if the mmci driver is probed before the respective GPIO controller (e.g. on the LPC32xx EA3250 board, the PCA9532 GPIO controller would be initialized via DT after mmci). Therefore, we defer mmci in this case. Signed-off-by: Roland Stigge <stigge@antcom.de> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-06-17ARM: 7426/1: mmc: mmci: Remove wrong error handling of gpio 0Roland Stigge
Zero is a valid GPIO and shouldn't be handled as an error return code from of_get_named_gpio(). It was a leftover from old code before getting pdata->gpio_*() was modified.

2012-06-17regulator: tps65023: Fix mask for LDOs output voltage select controlAxel Lin
According to the datasheet: The LDO_CTRL registers are used to set the output voltage of LDO1 and LDO2. LDO_CTRL[7] and LDO_CTRL[3] are reserved and should always be written to 0. Thus the mask for TPS65023_LDO_1 and TPS65023_LDO_2 should be 0x07 and 0x70 respectively. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-17ARM: OMAP: PM: Lock clocks list while generating summaryTodd Poynor
Commit a53025724052b2b1edbc982a4a248784638f563d (OMAP: Add debugfs node to show the summary of all clocks) introduced clock summary, however, we are interested in seeing snapshot of the clock state, not in dynamically changing clock configurations as the data provided by clock summary will then be useless for debugging configuration issues. So, hold the common lock when dumping the clock summary.

v3.5-rc1 fails to build when DT and iconnect is enabled because of this now none existant include file. Also remove the other two SPI include files, which are not needed with the move to DT.

2012-06-17x86-64, reboot: Allow reboot=bios and reboot-cpu override on x86-64H. Peter Anvin
With the revamped realmode trampoline code, it is trivial to extend support for reboot=bios to x86-64. Furthermore, while we are at it, remove the restriction that only we can only override the reboot CPU on 32 bits. Signed-off-by: H.
