* ARM: S3C64XX: DMA: Debugged alloc's with GFP_KERNEL flag in Intr context.Jassi2009-09-161-2/+2
| | | | | | | | | | | | | s3c2410_dma_enqueue makes call to kzalloc and dma_pool_alloc with GFP_KERNEL flag set, this can be an issue for drivers, like I2S, which call s3c2410_dma_enqueue from dma-bufferdone callback. Change the flag GFP_KERNEL to GFP_ATOMIC to avoid any problems.

* [ARM] S3C64XX: DMA supportBen Dooks2009-05-181-0/+722
Add support for the DMA blocks in the S3C64XX series of CPUS, which are based on the ARM PL080 PrimeCell system. Unfortunately, these DMA controllers diverge from the PL080 design by adding another DMA controller register and configuration for OneNAND.
