This reminds me of something: Because this syscall is
practically useless and the bitmap just uses up pcb bits
and kernel stack, I had once reduced it to a COMPAT
option, setting iopl if any access is allowed by the
bitmap, somewhere in a local tree, before the i386/amd64
unification.
This would make that the (faked) bitmap returned by
get_ioperm() would not necessarily be identical to the one
sent by set_ioperm(). I didn't find any userland program
using the ioperm calls, let alone reading back the bitmasks.
So how about getting the bitmask removed?

best regards
Matthias
