to the Xen host.

does not occur, leaving it as it is. When a TD is fetched with some
status bits are set to 1, it will return to Guest OS with these bits
set to 1 even this TD is executed successfully. Some Windows OS,
e.g. Windows 2000, will check status bits of TD in UHC interrupt
routine, treat it as a unsuccessful one if some status bits are set to
1 and discard the data. Other Windows OS just check USBSTS of UHC,
ignoring status field of TD unless the value of USBSTS indicates

bimodal blkback: Support multiple ring protocols.

This is needed for 32-on-64 support.  Right now there are three
protocols: native, x86_32 and x86_64.  If needed it can be extended.

Interface changes (io/blkif.h)
 * Define the x86_32 and x86_64 structs additionally to the native
   version.
 * Add helper functions to convert them requests to native.

Backend changes:
 * Look at the "protocol" name of the frontend and switch ring
   handling accordingly.  If the protocol node isn't present it
   assumes native protocol.
 * As the request struct is copied anyway before being processed (for
   security reasons) it is converted to native at that point so most
   backend code doesn't need to know what the frontend speaks.
 * In case of blktap this is completely transparent to userspace, the
   kernel/userspace ring is always native no matter what the frontend
   speaks.
