Per http://mediacenterguides.com/book/export/html/31 and investigation by Erin, we were missing these last three mappings to complete the mce key table. Lets remedy that.

2011-01-31drm/i915: Suppress spurious vblank interruptsChris Wilson
Hugh Dickins found that characters in xterm were going missing and oft delayed. Being the curious type, he managed to associate this with the new high-precision vblank patches; disabling these he found, restored the orderliness of his characters. The oddness begins when one realised that Hugh was not using vblanks at all on his system (fvwm and some xterms). Instead, all he had to go on were warning of a pipe underrun, curiously enough at around 60Hz. He poked and found that in addition to the underrun warning, the hardware was flagging the start of a new frame, a vblank, which in turn was kicking off the pending vblank processing code. There is little we can do for the underruns on Hugh's machine, a Crestline [965GM], which must have its FIFO watermarks set to 8. However, we do not need to process the vblank if we know that they are disabled... Reported-by: Hugh Dickins <hughd@google.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2011-01-31drm: Simplify and defend later checks when disabling a crtcChris Wilson
By setting the FB of a CRTC to NULL, we are turning off the CRTC (and so disable the unused encoders and connectors). As such we can simplify the later tests by making sure the set->mode is NULL. Setting the num_connectors to zero means that we do not need to loop over the unused connectors. All current usage appears correct, this only builds additional defense into the routine.

2011-01-31drm: Don't switch fb when disabling an outputChris Wilson
In drm_crtc_helper_set_config, we call drm_crtc_helper_set_mode which may return early and do no operation if the crtc is to be disabled. In this case we merrily swap to the new fb, discarding the old_fb believing that it has been cleaned up. However, due to the early return, the old_fb was not presented to the backend for correct reaping, and nor was the new one - which is about to be reaped via the drm_helper_disable_unused_functions(), leading to incorrect refcounting of the pinned objects.

2011-01-31watchdog: Fix broken nowatchdog logicMarcin Slusarz
Passing nowatchdog to kernel disables 2 things: creation of watchdog threads AND initialization of percpu watchdog_hrtimer. As hrtimers are initialized only at boot it's not possible to enable watchdog later - for me all watchdog threads started to eat 100% of CPU time, but they could just crash. Additionally, even if these threads would start properly, watchdog_disable_all_cpus was guarded by no_watchdog check, so you couldn't disable watchdog. To fix this, remove no_watchdog variable and use already existing watchdog_enabled variable.

2011-01-31dmaengine: imx-sdma: fix up param for the last BD in sdma_prep_slave_sg()Shawn Guo
As per the reference manual, bit "L" should be set while bit "C" should be cleared for the last buffer descriptor in the non-cyclic chain, so that sdma can stop trying to find the next BD and end the transfer. In case of sdma_prep_slave_sg(), BD_LAST needs to be set and BD_CONT be cleared for the last BD.

2011-01-31dmaengine: imx-sdma: return sdmac->status in sdma_tx_status()Shawn Guo
The sdmac->status was designed to reflect the status of the tx, so simply return it in sdma_tx_status(). Then dma client can call dma_async_is_tx_complete() to know the status of the tx. Signed-off-by: Shawn Guo <shawn.guo@freescale.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2011-01-31dmaengine i.MX SDMA: reserve channel 0 by not registering itSascha Hauer
We need channel 0 of the sdma engine for internal purposes. We accomplished this by calling dma_request_channel() in the probe function. This does not work when multiple dma engines are present which is the case when IPU support for i.MX31/35 is compiled in. So instead of registering channel 0 and reserving it afterwards simply do not register it in the first place. With this the dmaengine channel counting does not match sdma channel counting anymore, so we have to use sdma channel counting in the driver. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
