Subject: [PATCH] sparc64: #blocks64 disk node method
Return the 64bit number of blocks of storage associated with the device or
instance. Where a "block" is a unit of storage consisting of the number of
bytes returned by the package's "block-size" method. If the size cannot be
determined, or if the number of blocks exceeds the range return -1.
