fix cyclades.h for x86_64 (and probably others)
Browse files Browse the repository at this point in the history
At least on x86_64 the present cyclades.h is broken due to the wrong size
of uclong.  This affects, of course, both the kernel and the user-level
utilities.  The symptom is that cyzload refuses to load the firmware.  I
also managed to freeze the machine when unloading the module.

The patch below fixes this in an architecture-independent way.  I have
tested it with 2.6.19 and the driver works fine again with a Cyclades-Z on
an Athlon 64 X2.
