2012-04-05ARM: pm: preallocate a page table for suspend/resumeRussell King
Preallocate a page table and setup an identity mapping for the MMU enable code. This means we don't have to "borrow" a page table to do this, avoiding complexities with L2 cache coherency.

2012-04-05lib: devres: add convenience function to remap a resourceWolfram Sang
Almost every platform_driver does the three steps get_resource, request_mem_region, ioremap. This does not only lead to a lot of code duplication, but also a huge number of similar error strings and inconsistent error codes on failure. So, introduce a helper function which simplifies remapping a resource and make it hard to do something wrong and add documentation for it.

2012-04-03dmaengine/dw_dmac: Reconfigure interrupt and chan_cfg register on resumeViresh Kumar
In S2R all DMA registers are reset by hardware and thus they are required to be reprogrammed. The channels which aren't reprogrammed are channel configuration and interrupt enable registers, which are currently programmed at chan_alloc time. This patch creates another routine to initialize a channel. It will try to initialize channel on every dwc_dostart() call. If channel is already initialised then it simply returns, otherwise it configures registers. This routine will also initialize registers on wakeup from S2R, as we mark channels as uninitialized on suspend.
