David, thanks for this __incredibly__ __useful__ patch. I kicked it
around on sparc64 and found some more ignores to add, see below.
The vast majority of them vector to sys_ni_syscall in the i386 syscall
table.
sys_ugetrlimit is only necessary if the platform started out
using the non-SuS compliant sys_old_getrlimit()
The rest, like ioperm, iopl, modify_ldt, et al. are i386
specific.
