-Subject: [PATCH] bcm2835-sdhost: Allow for sg entries that cross pages
-
-The dma_complete handling code calculates a virtual address for a page
-then adds an offset, but if the offset is more than a page and HIGHMEM
-is in use then the summed address could be in an unmapped (or just
-incorrect) page.
-
-The upstream SDHOST driver allows for this possibility - copy the code
-that does so.
