X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=refs%2Fheads%2Fdma-mapping-includes;p=users%2Fhch%2Fmisc.git

Back in the day a lot of logic was implemented inline in dma-mapping.h and
needed various includes.  Move of this has long been moved out of line,
so we can drop various includes to improve kernel rebuild times.
