X-Git-Tag: v2.6.22-rc1~825^2~21 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cdf50b23bf83624708d0abbb381a1c1694e42e19;p=linux-2.6 sh: Kill off udivdi3 div64_32 wrapping. Previously we've been handling udivdi3 references and wrapping them in to div64_32() automatically. This doesn't get a lot of use, however, and as akpm noted in the recent thread on l-k: http://lkml.org/lkml/2007/2/27/241 we're better off simply ripping it out and going the do_div() route if there happen to be any places that need it.
