Are you just thinking that the multi compile with binary patching
should be introduced after the first merge?
Or do you have any idea other than the multi compile

Hi Eddie.
I looked into entry.S closely.
Unfortunately I found that ia64_leave_syscall() and
ia64_leave_kernel() includes invirtualizable instructions,

Oh, I misunderstood your patch.
I thought it just revert entry.S to original state. But it
paravirtualized conver and rfi with running_on_xen check.
Now I'm convinced that your patch works. Only one comment on
the patch itself is,
#ifdef CONFIG_XEN is necessary for !CONFIG_XEN case.
