Subject[PATCH] Clean up sys_ioperm stubs
Remove stubs for sys_ioperm for non-x86 arches, using sys_ni_syscall 
instead where applicable.

PS. Can we nuke the KDADDIO etc. ioctls in drivers/char/vt_ioctl.c?
They apparently were used by ancient versions of X, but nothing should
be using them now, considering they are limited to the VGA ports only (I
also checked svgalib).
