- * Asm versions of Xen pv-ops, suitable for either direct use or
- * inlining.  The inline versions are the same as the direct-use
- * versions, with the pre- and post-amble chopped off.
- *
- * This code is encoded for size rather than absolute efficiency, with
- * a view to being able to inline as much as possible.
- *
- * We only bother with direct forms (ie, vcpu in pda) of the
- * operations here; the indirect forms are better handled in C, since
- * they're generally too large to inline anyway.
