2015-12-12MIPS: fix DMA contiguous allocationQais Yousef
Recent changes to how GFP_ATOMIC is defined seems to have broken the condition to use mips_alloc_from_contiguous() in mips_dma_alloc_coherent(). I couldn't bottom out the exact change but I think it's this commit d0164adc89f6 ("mm, page_alloc: distinguish between being unable to sleep, unwilling to sleep and avoiding waking kswapd"). GFP_ATOMIC has multiple bits set and the check for !(gfp & GFP_ATOMIC) isn't enough. The reason behind this condition is to check whether we can potentially do a sleeping memory allocation. Use gfpflags_allow_blocking() instead which should be more robust.

Similar to how arm allows using selecting between bootloader arguments, dtb arguments and both, allow to select them on mips. But since we have less control over the place of the dtb do not modify it but instead use the boot_command_line for merging them.

2015-11-11MIPS: Lantiq: Fix check for return value of request_mem_region()Hauke Mehrtens
request_mem_region() returns a pointer and not an integer with an error value. A check for "< 0" on a pointer will cause problems, replace it with not null checks instead. This was found with sparse.
