This openbios-grubfs-ext2fs-block.patch fixes a problem where inode
pointer is truncated to 32bit integer and then sign-extended to 64bit
integer while passing second pointer argument to ext2_rdfsb.

The current SVN version currently fails to work on machines that have
strict alignment requirements, for example the SPARC target. This is due
to the way the struct fat_bpb in fs/grubfs/fat.h is defined and accessed
(through FAT_CVT_U16) to avoid padding. Some 16 bits fields like
bytes_per_sect are thus accessed unaligned.
The patch below takes the same approach as for other structures in
openbios, it declares the structure as packed, and lets GCC do the right
things to access those unaligned field.
