This patch:
- creates asm-generic/swiotlb.h
- makes it use 'enum dma_data_direction dir' rather than 'int dir'
- updates x86-64 and IA64 to use the common swiotlb.h
- fixes the resulting fall out (s/int dir/enum dma_data_direction dir/
all over the place).
Generated code should be functionally equivalent. Compile tested on
x86-64 (w/ gart, nommu and swiotlb) and IA66 (defconfig). Patch is
against 2.6.16-rc1-mm4.
