This moves flush_write_buffers() in asm-generic/dma-mapping-common.h to arch/x86/kernel/pci-nommu.c. The purpose of this patch is that, we can avoid defining NULL flush_write_buffers() on IA64 and SPARC. dma-mapping-common.h is used by X86 and IA64 (and SPARC soon) but only X86 with CONFIG_X86_OOSTORE or CONFIG_X86_PPRO_FENCE actually uses flush_write_buffers(). CONFIG_X86_OOSTORE or CONFIG_X86_PPRO_FENCE is usable with only kernel/pci-nommu.c (that is, not usable with other X86 IOMMU implementations such as SWIOTLB, VT-d, etc) so we can safely move flush_write_buffers() in asm-generic/dma-mapping-common.h to arch/x86/kernel/pci-nommu.c.
