Hi Richard,

The following patch fixes a compilation problem on the Jensen (due to
the -Werror introduction).

BTW, the Jensen doesn't boot anymore :

Linux version 2.5.63 (maz@panther) (gcc version 3.2 (Debian)) #1 Thu Feb 27 21:3
Booting on Jensen using machine vector Jensen from SRM
Command line: ro root=/dev/sda1 console=ttyS0
memcluster 0, usage 1, start        0, end      256
memcluster 1, usage 0, start      256, end     8192
freeing pages 256:384
freeing pages 738:8192

Max ASN from HWRPB is bad (0xf)

Kernel command line: ro root=/dev/sda1 console=ttyS0
opDEC fixup enabled.

Calibrating delay loop... 292.12 BogoMIPS
Memory: 59880k/65536k available (2012k kernel code, 3512k reserved, 163k data, )
Dentry cache hash table entries: 8192 (order: 4, 131072 bytes)

>>> 

It used to run 2.5.61 just fine (with minor tricks...). Do you have
any idea ?

Thanks,

        M.
