Paulo Alcantara (SUSE) 8eecd1c2e5 cifs: Add support for root file systems
Introduce a new CONFIG_CIFS_ROOT option to handle root file systems
over a SMB share.

In order to mount the root file system during the init process, make
cifs.ko perform non-blocking socket operations while mounting and
accessing it.
