[Xen-devel] [PATCH 0 of 5] Rombios PIO performance

This patch series is the result of some analysis to improve the boot peformance
of HVM guests for XenServer.

Tests were performed with Win7 as the HVM guest, but the fixes apply to all HVM
guests.  All improvements are by reducing the number of PIO traps from rombios,
through Xen to Qemu; some completely needless and some by knowing how Qemu is
going to react.
