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".
