[Xen-devel] [PATCH] perfc_defn.h - increase VMX reason size array

[Ben Thomas <bthomas@xxxxxxxxxxxxxxx>]

If I'm reading the spec correctly, the April 2005 Intel Virtualization
Technology Specification (Appendix A1) indicates that there are 44
potential exit reason codes.  Based upon this, increase the size of
the PERFCOUNTER_ARRAY for vmexits.
