What is the best way to allocate some non-cacheable memory for I/O use? Right now we are going to setup a BAT table with a non-cacheable memory region and use that for all I/O, but does linux have a nice neat function to grab a page and set it up non-cacheable for us? I was reading in the archives that the #define PAGE_NOCACHE doesn't work.
