Tue Sep 28 09:57:24 UTC 2010
From: Nikunj A. Dadhania <nikunj at linux.vnet.ibm.com>
v3:
* Squased all the remote driver changes to one single big patch and
auto-generated is around 40%
* Implements domainSetMemoryParameters and domainGetMemoryParameters for remote
driver
daemon/remote.c
src/remote/remote_driver.c
* Auto generate the files using rpcgen and helper scripts in daemon/ directory
src/remote/remote_protocol.x
daemon/remote_dispatch_args.h
daemon/remote_dispatch_prototypes.h
daemon/remote_dispatch_ret.h
daemon/remote_dispatch_table.h
src/remote/remote_protocol.c
src/remote/remote_protocol.h
