IDE patches - fix the logical CHS translation a guest selects with INITIALIZE DEVICE PARAMETERS: reject a translation the device may not accept instead of dying on a division by zero, report the default translation in IDENTIFY DEVICE words 1, 3 and 6 and the one in effect in words 54 to 58, keep those words in sync when the translation changes, migrate both the translation and the SET FEATURES 0xCC revert flag, and return the power-on defaults on a hardware reset rather than on every reset - harden the IDE and AHCI state a guest or an incoming migration stream can reach: reject an out-of-range PIO transfer window on load, refuse a PIO transfer with no command header, clear cur_cmd when the command list is unmapped, treat a failed PRDT walk as a transfer failure, reject a command header with an invalid FIS length, and drain the ports on teardown so that a request cannot outlive an unplug - report ATAPI UDMA5 with a matching standard and cable - extend the IDE/AHCI qtest coverage for all of the above Signed-off-by: Denis V.
