Add the initial support for DAX file operations to XFS. This includes the necessary block allocation and mmap page fault hooks for DAX to function. Note that there are changes to the splice interfaces to ensure that for DAX splice avoids direct page cache manipulations and instead takes the DAX IO paths for read/write operations. Signed-off-by:
