Model and version_id are already documented. It is only syscall_linkage that
is undocmented, and that would be my fault.
Meanwhile, you can find info about it in the gcc sources, in the file
gcc/config/ia64/ia64.c. The overlapping register windows implemented by the
IA-64 architecture can cause kernel internal data to leak out to user processes
if one is not careful. The syscall_linkage attribute modies the ABI slightly
to prevent this, and it should be used on user entry points to the kernel.
