* [media] v4l2-device: fix a macro definitionGuennadi Liakhovetski2011-04-13

* [media] cx18: Fix list BUG for IDX stream, triggerable in cx18_probe() error ↵Andy Walls2011-04-13
| | | | | | | | | | | | | | clean up, If allocating stream buffers for one of the primary streams (e.g. YUV) failed during card probe, the error path clean up would try to manipulate the yet unitialized IDX stream structures. This caused a BUG due to unitialized list heads. Detect that case and ignore the uninitialized IDX stream.

* [media] FLEXCOP-PCI: fix __xlate_proc_name-warning for flexcop-pciPatrick Boettcher2011-04-04
| | | | | | | | | | | This patch fixes the warning about bad names for sys-fs and other kernel-things. The flexcop-pci driver was using '/'-characters in it, which is not good. This has been fixed in several attempts by several people, but obviously never made it into the kernel.

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.

Avoids easy namespace collisions and will make it easier to consolidate with other implementations. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
| * | | | | | | powerpc/pmac/smp: Fix CPU hotplug crashes on some machinesBenjamin Herrenschmidt2011-04-01

This uses the newly added bringup_done() callback to move the close along with other housekeeping calls, and adds a CPU notifier to re-open the i2c bus around subsequent hotplug operations Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| * | | | | | | powerpc/pmac/smp: Properly NAP offlined CPU on G5Benjamin Herrenschmidt2011-04-01

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>
