I agree with you.
For the minimal domU, binary patch isn't needed anymore now
so that I removed paravirt_(core|entry).(c|h) completely.
After merging up minimal domU stuff to the upstream,
let's readd those files with consistent file names
(probably into paravirt.c).
I also found that the file nam
on is necessary.

Unfortunately I found that ia64_leave_syscall() and
ia64_leave_kernel() includes invirtualizable instructions,
cover instruction with psr.ic = 0 so that those paravirtualization
is inevitable. (ia64_switch_to() doesn't need paravirtualization though.)
