+[HVM] qemu mouse: Adds support for USB mouse/tablet status check and
+restricts Universal Host Controller interrupt generating when received
+NAK in interrupt transfer.
+
+According to usb spec, USB mouse/tablet device returns NAK to host
+controller if its status does not alter in interrupt transfer.
+And UHC should leave a TD active when receiving NAK and execute this
+incompleted TD in a subseqent frame. UHC only generates an interrupt
+on complete after the TD with ICO bit is completed.
+
+This patch make UHC & USB mouse/tablet behave consistently with spec.

+[HVM] qemu: Add guest address-space mapping cache.
+
+On IA32 host or IA32 PAE host, at present, generally, we can't create
+an HVM guest with more than 2G memory, because generally it's almost
+impossible for Qemu to find a large enough and consecutive virtual
+address space to map an HVM guest's whole physical address space.
+The attached patch fixes this issue using dynamic mapping based on
+little blocks of memory.
