[PATCH] EDD: add edd=off and edd=skipmbr options
EDD: add edd=off and edd=skipmbr command line options
New command line options
edd=off (or edd=of)
edd=skipmbr (or edd=sk)
runtime options for disabling all EDD int13 calls completely, or for
skipping the int13 READ SECTOR calls, respectively.
These are provided to allow Linux distributions to include CONFIG_EDD=m, yet
allow end-users to disable parts of EDD which may not work well with their
system's BIOS.
I incorporated comments from Randy Dunlap, and got an ack from Andi Kleen.
