6412648 VIO service drivers auto-unload after some time

6413569 Possible memory leaks needs to be investigated.
6423722 vds should use finer-grained locking for better performance
6429738 LDom panics using a destroyed ldc
6431111 LDOM manager should use P_FAULTED state for cpu instead of P_OFFLINE/
6431300 can not enter '~' character on a ldom's console
6431458 vDisk drivers need to handle read/write requests asynchronously
6437436 ldc read/write operations are serialized due to a common lock
6437766 vDisk VTOC should handle the timestamp field
6440543 vSwitch/vNet should use aligned IP frame headers
6440553 vNet/vSwitch should reuse previously allocated mblks
6442270 vDisk server should set FREAD and FWRITE mode when calling ldi_ioctl
6442851 Remove VLDC max write_pa limit
6442973 vntsd dumps core with assertion failure message
6443193 vDisk client incorrectly implements DKIOCSGEOM ioctl
6443198 vDisk client incorrectly caches new VTOC on DKIOCSVTOC ioctl
6444392 vswitch/vnet should set end_idx to -1 for increased performance
