Convert existing FreeBSD vmware_hvcall function to take a channel and parameter arguments. Added vmware_guestrpc_cmd() to send GuestRPC commands to the VMware hypervisor. The sbuf argument is used for both the command to send and to store the data to return to the caller. The following KPIs can be used to get and set FreeBSD-specific guest information in key/value pairs: * vmware_guestrpc_set_guestinfo - set a value into the guestinfo.fbsd.<keyword> key * vmware_guestrpc_get_guestinfo - get the value stored in the guestinfo.fbsd.<keyword> key Add VMware devices to x86 NOTES Reviewed by: jhb Obtained from: Juniper Networks, Inc.
