* | | | | | | | Remove unnecessary union in grant table map/unmap ops.akw27@arcadians.cl.cam.ac.uk2005-08-137-26/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All addresses, host virtual and PTEs, are now passed in the cunningly ambiguous "host_addr" field, rather than in an anonymous union.

This particular problem was that one function was being called with self instead of the right argument and another function's return value was being used when it didn't actually return anything. This patch also improves the error handling a bit by making sure we don't thrown an exception on a log statement with a None value. In general, one should always use the % formatter instead of concatination for strings in Python (even though this is not what this patch does). Signed-off-by: Anthony Liguori

The contains_pte flag is used to indicate what sort of address is in the map request. Additionally, this patch: - fixes grant mappings to user space. - fixes overflow testing when you run out of maptrack entry space.

The reason is "vif" is dealt with as a "vbd" device. This patch fixes this issue by dealing with "vbd" and "vif " separately, removing "macaddr" arg and parsing mac address from "vif" instead. Also, the vbd doesn't have to be a file anymore, but can be a physical disk partition. Signed-off-by: Yunfeng Zhao <yunfeng.zhao@intel.com> Signed-off-by: Arun Sharma <arun.sharma@intel.com>
