Egads!  OK, I see why this is a mess.

I guess we should be creating the metadata from the syscall tables
instead of from the syscall definitions, but I guess that's currently
a nasty per-arch mess.

Yep.

I wonder: could more of it be dynamically allocated?  I.e. statically
generate metadata with args and name and whatever but without any nr.
Then dynamically allocate the map from nr to metadata?

Could we at least have an array of (arch, nr) instead of just an array
of nrs in the metadata?

I guess I'm not following you on what would be used for "arch".

Whatever syscall_get_arch() would return for the syscall.  For x86,
for example, most syscalls have a compat nr and a non-compat nr.  How
does tracing currently handle that?
