Thank you for your update.

I've incorporated feedback from all folks I hope. Would this be satisfactory?

Subject: [PATCH] README, xen/Makefile: Update to Xen 4.5.0

Expand the README file to give a brief view of what went in
Xen 4.5.0. Also change the Makefile to not use the '-rc'
postfix.

+large scale machines during bootup and for PCI passthrough; multiple IO-REQ
