This adds the partuuid string to struct cdev in order to have this
available for constructing a suitable Linux root=PARTUUID= option
for booting Linux.

LBAs are numbered starting from zero so the last LBA # would be equal
to total number of blocks minus one.

With upcoming EFI payload support the efi.h file will diverge
from the kernel, so move it from include/linux/ to include/

The FSF address has changed; The FSF site says that
address is
Free Software Foundation
51 Franklin Street, Fifth Floor

(see http://www.fsf.org/about/contact/)
Instead of updating it each time the address changes,
just drop it completely treewide.

DOS MBRs might contain an extended partition that holds several logical
partitions. Add these to the partitions of the block device.

The code used to ineffectively take the end of the last partition as guess
for the disk size. Better use the end of the partition that has its end
rearmost.
Also return an unsigned type instead of int as the result is always
non-negative.

The NT disk Signature is a unique 32-bit value in the MBR allowing
to identify a MSDOS partitioned disk. The signature can be used to
specify the Linux rootfs.
This patch adds support for the NT disk Signature in the form of a
device parameter which can both be read and written.

Some drivers use blk->ops->read/write. This bypasses the caching block
layer and was never intended like this. The upper API to the block layer
is the cdev layer. This patch adds block_read and block_write functions
and uses them where appropriate.

so you can have part by num or name
not by GUID as this is a non human reading name
