[microblaze-uclinux] patch for unaligned.h (warning: left shift count >= width of type)
The following patch has been applied to CVS to fix a problem noticed
in smbfs where a 64 bit value was
being truncated to 32 bits. You will know if this problem exists by
the following compiler warning being
displayed during the building of the kernel.
warning: left shift count >= width of type
This problem seems to show up mainly in the file systems (fat,
smbfs, msdos partitions etc).
