Weird. My drivers/mmc/mmc.c looks

...
mmc_set_data_timeout(&data, card, 0);

data.blksz = 1 << 3;
data.blocks = 1;
data.flags = MMC_DATA_READ;
data.sg = &sg;
data.sg_len = 1;
...

without any patch. Looking at line ~999 of

http://source.mvista.com/git/gitweb.cgi?p=linux-omap-2.6.git;a=blob;h=ee8863c123e37881e0f35ee658a15fd5e925ad31;hb=591db7639fd7e2b2ae3f82851ee1d25beac714c4;f=drivers/mmc/mmc.c#999

it's the same. So I don't have to touch mmc.c for my patch 
above.

Best regards
