Hmmm... kernel_cap_t is a structure that might not fit into a single register.
It occurs to me that you might be better off returing the old caps through a
pointer argument.  It should still work, though.

The SElinux and syscalls LTP testscripts work okay for these patches when
ported to linux-next.  The filecaps LTP testscript can't be used on Fedora 9
as the setcap command is used incorrectly.
