| * | | xen: make use of pte_t unionJeremy Fitzhardinge2008-04-241-13/+11Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pte_t always contains a "pte" field for the whole pte value, so make use of it.

Instead, point RETX at a safe location from which to fetch three NOPs. This safe location is now in the fixed code area, and also used for certain anomaly workarounds, to ensure that user space can find a valid ICPLB when things are built with CONFIG_MPU. Also, save I/DCPLB_FAULT_ADDRESS when lowering to level 5, since the hardware reg is valid only at exception level.
