fs/partitions/msdos: add support for large disks
In order to use disks larger than 2TiB on Windows XP, it is necessary to
use 4096-byte logical sectors in an MBR.
Although the kernel storage and functions called from msdos.c used
"sector_t" internally, msdos.c still used u32 variables, which results in
the ability to handle XP-compatible large disks.
This patch changes the internal variables to "sector_t".
Daniel said: "In the near future, WD will be releasing products that need
this patch".
