2011-04-13[media] sh_mobile_csi2: fix module reloadingGuennadi Liakhovetski
If the camera host driver (sh_mobile_ceu_camera.c) is unloaded and then reloaded, probe will fail, because camera client .set_bus_param() and .query_bus_param() methods have been set to NULL.

2011-04-13[media] soc-camera: fix a recent multi-camera breakage on sh-mobileGuennadi Liakhovetski
With the introduction of CSI2 support on sh-mobile, the host driver switched to using v4l2_device_call_until_err() with grp_id == 0 to call subdev operations on the sensor and the CSI2 subdev. However, this has broken multi-client set ups like the one on migor, because that way all operations get called on both clients. To fix this add a grp_id and set it to the client private context.

2011-04-01ALSA: pcm: fix infinite loop in snd_pcm_update_hw_ptr0()Kelly Anderson
When period interrupts are disabled, snd_pcm_update_hw_ptr0() compares the current time against the time estimated for the current hardware pointer to detect xruns. The somewhat fuzzy threshold in the while loop makes it possible that hdelta becomes negative; the comparison being done with unsigned types then makes the loop go through the entire 263 negative range, and, depending on the value, never reach an unsigned value that is small enough to stop the loop. Doing this with interrupts disabled results in the machine locking up. To prevent this, ensure that the loop condition uses signed types for both operands so that the comparison is correctly done. Many thanks to Kelly Anderson for debugging this.

2011-04-01powerpc/pmac/smp: Properly NAP offlined CPU on G5Benjamin Herrenschmidt
The current code soft-disables, and then goes to NAP mode which turns interrupts on. That means that if an interrupt occurs, we will hit the masked interrupt code path which isn't what we want, as it will return with EE off, which will either get us out of NAP mode, or fail to enter it (according to spec). Instead, let's just rely on the fact that it is safe to take decrementer interrupts on an offline CPU and leave interrupts enabled. We can also get rid of the special case in asm for power4_cpu_offline_powersave() and just use power4_idle(). Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
