Hi all !
Could someone explain me how those directive (__init, __openfirmware,
__pmac, ...) works in the kernel ? I guess those are directive for the
linker, and I also guess that __init marked sections will be removed from
memory after kernel initialisation, but what are the other ones ?
I ask this because I added a couple of ioctl to via-pmu (*), and as soon
as I added calls to get_user and put_user to the function, the kernel
refused to link. if I remove the __openfirmware directive from the ioctl
function, then it links fine.
(*) Cort, I have backlight control working on wallstreet, those ioctls
are for allowing user-space control of it too, I think you can remove
your stuff from via-pmu.c. I'll send you patches as soon as I have
cleaned them up a little bit, it's not urgent for 2.2.
