If the SCTLR.UMA trap bit is set then attempts by EL0 to update the PSTATE DAIF bits via "MSR DAIFSet, imm" and "MSR DAIFClr, imm" instructions will raise an exception. We were failing to set the syndrome information for this exception, which meant that it would be reported as a repeat of whatever the previous exception was. Set the correct syndrome information.

Add a CPU state exception target EL field that will be used for communicating the EL to which an exception should be routed. Add a disassembly context field for tracking the EL3 architecture needed for determining the target exception EL. Add a target EL argument to the generic exception helper for callers to specify the EL to which the exception should be routed. Extended the helper to set the newly added CPU state exception target el. Added a function for setting the target exception EL and updated calls to helpers to call it.

When migrating a guest, be sure to include the vector registers. The vector registers are defined in a subsection, similar to the existing subsection for floating point registers.

Handle the actual syncing of the vector registers with kernel space, via the get/put register IOCTLs. The vector registers that were introduced with the z13 overlay the existing floating point registers. FP registers 0-15 are the high-halves of vector registers 0-15. Thus, remove the freg fields and replace them with the equivalent vector field to avoid errors in duplication. Moreover, synchronize either the vector registers via kvm_sync_regs, or floating point registers via the GET/SET FPU IOCTLs.

Currently QEMU dynamically generates mac address for the NIC which doesn't specify the mac address. But when we hotplug a NIC without specifying mac address, the mac address will increase for the same NIC along with hotplug and hot-unplug, and at last it will overflow. And if we codeplug one NIC with mac address e.g. "52:54:00:12:34:56", then hotplug one NIC without specifying mac address and the mac address of the hotplugged NIC is duplicate of "52:54:00:12:34:56". This patch add a mac_table to record the usage status and free the mac address when the NIC is unrealized.

Error reporting for netdev_add is broken: the net_client_init_fun[] report the actual errors with (at best) error_report(), and their caller net_client_init1() makes up a generic error on top. For command line and HMP, this produces an mildly ugly error cascade. In QMP, the actual errors go to stderr, and the generic error becomes the command's error reply. To fix this, we need to convert the net_client_init_fun[] to Error. To permit fixing them one by one, add an Error ** parameter to the net_client_init_fun[]. If the call fails without returning an Error, make up the same generic Error as before. But if it returns one, use that instead. Since none of them does so far, no functional change.
