[parisc-linux] enumerating devices from user space

[Lyonel Vincent]

Hi Bruno,

The ioctl sounds great to me.
On which device would you "attach" it (as some of the devices I'd like
to report don't even have an entry in /dev), create a new one? Correct
me if I'm wrong (I don't know much about IOCTLs)
If you want me to help testing/developing, I have a 9000/C180 w/ Debian
(unstable) ready to use.

cheers,
lv.

PS: being PA-RISC dependent is not a problem, I already have ifdefs for
x86, PowerPC and Alpha
