This fixes the spurious interrupt issue on a DMA channel. In OMAP sDMA, contrast to the SDMA.DMA4_CSRi registers, the SDMA.DMA4_IRQSTATUS_Lj registers are updated regardless of the corresponding bits in the SDMA.DMA4_IRQENABLE_Lj registers. Since there are four sDMA interrupt lines and if more than one line is actively used by two concurrently running sDMA softwares modules,then the spurious interrupt can be observed on the other lines. Fix in this patch will only dispatch the relevant and enabled interrupts on a particular line thus perevting spurious IRQ.

This patch set up a cmdline option for omap dma for masking the available channels. It is needed since the OMAP DMA is a system wide resource and can be used by another software apart from the kernel. To reserve the omap SDMA channels for kernel dma usage, use cmdline bootarg "omap_dma_reserve_ch=". The valid range is 1 to 32.

This patch extends command line option "i2c_bus=bus_id,clkrate" so that it allow to register additional I2C busses that are not registered with omap_register_i2c_bus from board initialization code. Purpose of this is to register additional board busses which are routed to external connectors only without any on board I2C devices.

This patch adds a new command line option "i2c_bus=bus_id,clkrate" into I2C bus registration helper. Purpose of the option is to override the default board specific bus speed which is supplied by the omap_register_i2c_bus. The default bus speed is typically set to speed of slowest I2C chip on the bus and overriding allow to use some experimental configurations or updated chip versions without any kernel modifications.

Also remove board-omap3beagle.h that is not included anywhere, and move protoype for voiceblue_reset() from board-voiceblue.h to system.h. After this patch there are still board-ams-delta.h, board-sx1.h and board-voiceblue.h that export some functions. These could be removed if the functions were moved under drivers.

With a sufficiently new compiler and binutils, code which wasn't previously generating .eh_frame sections has begun to. Certain architectures (powerpc, in this case) may generate unexpected relocation formats in response to this, preventing modules from loading. While the new relocation types should probably be handled, revert to the previous behaviour with regards to generation of .eh_frame sections. (This was reported against Fedora, which appears to be the only distro doing any building against gcc-4.4 at present: RH bz#486545.)

This patch fixes bug #12208: Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12208 Subject : uml is very slow on 2.6.28 host This turned out to be not a scheduler regression, but an already existing problem in ptrace being triggered by subtle scheduler changes. The problem is this: - task A is ptracing task B - task B stops on a trace event - task A is woken up and preempts task B - task A calls ptrace on task B, which does ptrace_check_attach() - this calls wait_task_inactive(), which sees that task B is still on the runq - task A goes to sleep for a jiffy - ... Since UML does lots of the above sequences, those jiffies quickly add up to make it slow as hell. This patch solves this by not rescheduling in read_unlock() after ptrace_stop() has woken up the tracer. Thanks to Oleg Nesterov and Ingo Molnar for the feedback.
