A much simpler, although not quite as pretty nor as flexible, solution is to print 64 bit integers in two halves. This only works for hex printouts and the %08X (zero fill with 8 positions) is necessary to make it work.
printf("This is a hex 64 bit long: %08X%08X", (unsigned int)(data >> 32), (unsigned int)data);

Here are two patches. First patch gives vsprintf the ability to print 64bit
integers by using
L as the qualifier Eg printf("a 64 bit number: %Lx", a64bitnumber); Also adds simple_strtoull (that handles long longs)
Second patch adds 48bit addressing support to the IDE interface. Needs the vsprintf patches to be able to print larger capacity.
Ummm... actually I don't like to increase the memory footprint for all systems for a feature which nearly nobody ever needs. I think it should be possible to print the large capacities without using such data formats (I guess you don't need 64 bit precision).
Best regards,
