Here you go. :-) >=20 > Subject: [PATCH 2.6.26] sg: reimplement sg mapping iterator >=20 I've converted my code to use your implementation instead, and it seems to be working perfectly. How comfortable to you feel about your patch? :) This fixes a big problem in the sdhci driver where falling back on PIO (because of hw DMA bugs) would create lots of potential issues as the driver couldn't access highmem pages. I'd like to get this fix in for 2.6.27, which means that your patch also needs to go in now. Rgds --=20 -- Pierre Ossman WARNING: This correspondence is being monitored by the Swedish government.
