2008-10-23	x86: use GFP_DMA for 24bit coherent_dma_mask	FUJITA Tomonori	1	-1/+3
	dma_alloc_coherent (include/asm-x86/dma-mapping.h) avoids GFP_DMA allocation first and if the allocated address is not fit for the device's coherent_dma_mask, then dma_alloc_coherent does GFP_DMA allocation. This is because dma_alloc_coherent avoids precious GFP_DMA zone if possible. This is also how the old dma_alloc_coherent (arch/x86/kernel/pci-dma.c) works. However, if the coherent_dma_mask of a device is 24bit, there is no point to go into the above GFP_DMA retry mechanism. We had better use GFP_DMA in the first place.

2008-10-22	x86: Fix ASM_X86__ header guards	H. Peter Anvin	1	-3/+3
	Change header guards named "ASM_X86__" to "_ASM_X86_" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
