The commit 3b4c34aac7abea4754059084d0eef667a1993ac8 "s5p-fimc: Add support for VIDIOC_PREPARE_BUF/CREATE_BUFS ioctls" added a handler for VIDIOC_CREATE_BUFS ioctl, but the queue_setup callback wasn't updated to properly interpret the pixel format.

2012-05-08powerpc: Fix broken cpu_idle_wait() implementationThomas Gleixner
commit 771dae818 (powerpc/cpuidle: Add cpu_idle_wait() to allow switching of idle routines) implemented cpu_idle_wait() for powerpc. The changelog says: "The equivalent routine for x86 is in arch/x86/kernel/process.c but the powerpc implementation is different.": Unfortunately the changelog is completely useless as it does not tell _WHY_ it is different. Aside of being different the implementation is patently wrong. The rescheduling IPI is async. That means that there is no guarantee, that the other cores have executed the IPI when cpu_idle_wait() returns. But that's the whole purpose of this function: to guarantee that no CPU uses the old idle handler anymore. Use the smp_functional_call() based implementation, which fulfils the requirements.
