[Why] Programming DCN is explicitly forbidden during idle optimzations allowed state. Existing implemenation relies on OS/DM, which is not robust. Instead DC should sequence this. Note that DC will not re-enter idle optimized state on its own, it is only responsible for catching out of sequence calls. It is still DM responsibility to sequence appropriate for optimized power, but this change removes the requirement for DM to cover the .1% case. [How] - elevate updates during idle optimized state to full updates - disable idle power optimizations prior to programming Signed-off-by:

The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'radeon_gart_table_ram_alloc()' GFP_KERNEL can be used because its callers already use this flag. Both 'r100_pci_gart_init()' (r100.c) and 'rs400_gart_init()' (rs400.c) call 'radeon_gart_init()'.
