Hi,

Here is a couple of fixes for the 2.4.x sparc64 users.

The first one fixes a bug in the fore200e driver. A field
was left uninitialized in the sparc64-specific code.

The second one applies to the generic linux-atm code. The VCC flags
are defined as an unsigned int (32 bit) while the set_bit() & friends
functions expect an unsigned long (64 bit in sparc64 kernel space).
Consequently, the beginning of the VCC structure (e.g. the VPI field)
is overwritten.
