HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.

add @uptodate argument to end_that_request_last() and @error to rq_end_io_fn(). there's no generic way to pass error code to request completion function, making generic error handling of non-fs request difficult (rq->errors is driver-specific and each driver uses it differently). this patch adds @uptodate to end_that_request_last() and @error to rq_end_io_fn(). for fs requests, this doesn't really matter, so just using the same uptodate argument used in the last call to end_that_request_first() should suffice. imho, this can also help the generic command-carrying request jens is working on.

Select a block size for IO based on the read and write block size combinations, and whether the card supports partial block reads and/or partial block writes. If we are able to satisfy block reads but not block writes, mark the device read only. Signed-off-by:

We were passing set_capacity() the capacity we calculated in terms of the number of blocks on the card, which happened to be the right units for 512-byte block cards. However, with 1024-byte block cards, we end up setting the capacity to half the number of blocks. Fix this by shifting by the appropriate amount. Thanks to Todd Blumer for pointing this out. Use get_capacity() to report the card capacity, rather than recalculating it from the CSD information. Finally, use our chosen IO block size for the SET_BLOCKLEN command rather than the CSD read block size. Currently these are equivalent, but will not be in the future. Signed-off-by:

If a card doesn't support the "write block" command class then any attempts to open the device should reflect this by denying write access. Signed-off-by:

Defines for the different command classes as defined in the MMC and SD specifications. Removes the check for high command classes and instead checks that the command classes needed are present. Previous solution killed forward compatibility at no apparent gain. Signed-of-by: Pierre Ossman

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
