[PATCH 1/10] ioperm & iopl

[-- Attachment #1: Type: text/plain, Size: 447 bytes --]

This patch series is basically a reworked version of orc's previous
patch.
From what orc said, the first patch should provide enough to build
Xorg; I haven't tested this yet.
A few more patches are syscall wrappers (splice) or trivial
functions (finite).
Finally, there are several aliases.

With that, I'm sending the first patch.
This adds ioperm & iopl along with io.h, though a full io.h has
several more syscalls.
