They have already gone into i386 (and others) ... so ia64 is playing
catch-up to provide the same functionality that exists on other
architectures.  Not to mention that I wasn't consulted, they just
appeared there one day out of -mm or linus.

Many people want to add new system calls, not all of them succeed.
Allocation of system call numbers can wait until there is general
agreement that the call is going to be accepted.
