Thanx a lot Jeremy!
In addition to removing the special case for 0x80 in arch/x86/traps.c:do_set_trap_table(), will I also have to define an entry point in xen/arch/x86/x86_32/entry.S as ENTRY(system_call) ??
Could you please tell me other required modifications that I will have to make?

I want to modify xen 3.3.0 so that control transfers to xen after system calls. How can I disable fast system call handlers, so that int 0x80h functions just like all other interrupts.
