Since a few commands are using 'gen': false, they are not registered
automatically by the generator. Register manually instead.
This is in preparation for removal of qapi 'middle' mode generation.
Note that qmp_init_marshal() function isn't run yet, so the commands
aren't actually registered, until module_call_init(MODULE_INIT_QAPI) is
added in a later patch.

and (2) merging weaker fences into a stronger fence.

The return address argument to the softmmu template helpers was
confused. In the legacy case, we wanted to indicate that there
is no return address, and so passed in NULL. However, we then
immediately subtracted GETPC_ADJ from NULL, resulting in a non-zero
value, indicating the presence of an (invalid) return address.
Push the GETPC_ADJ subtraction down to the only point it's required:
immediately before use within cpu_restore_state_from_tb, after all
NULL pointer checks have been completed.
This makes GETPC and GETRA identical. Remove GETRA as the lesser
used macro, replacing all uses with GETPC.

Previously we allowed fully unaligned operations, but not operations
that are aligned but with less alignment than the operation size.
In addition, arm32, ia64, mips, and sparc had been omitted from the
previous overalignment patch, which would have led to that alignment
being enforced.

d1f6af6 "kvm-irqchip: simplify kvm_irqchip_add_msi_route" was a cleanup
of kvmchip routing configuration, that was mostly intended for x86.
However, it also contains a subtle change in behaviour which breaks EEH[1]
error recovery on certain VFIO passthrough devices on spapr guests. So far
it's only been seen on a BCM5719 NIC on a POWER8 server, but there may be
other hardware with the same problem. It's also possible there could be
circumstances where it causes a bug on x86 as well, though I don't know of
any obvious candidates.
Prior to d1f6af6, both vfio_msix_vector_do_use() and
vfio_add_kvm_msi_virq() used msg == NULL as a special flag to mark this
as the "dummy" vector used to make the host hardware state sync with the
guest expected hardware state in terms of MSI configuration.
Specifically that flag caused vfio_add_kvm_msi_virq() to become a no-op,
meaning the dummy irq would always be delivered via qemu. d1f6af6 changed
vfio_add_kvm_msi_virq() so it takes a vector number instead of the msg
parameter, and determines the correct message itself. The test for !msg
was removed, and not replaced with anything there or in the caller.
With an spapr guest which has a VFIO device, if an EEH error occurs on the
host hardware, then the device will be isolated then reset. This is a
combination of host and guest action, mediated by some EEH related
hypercalls. I haven't fully traced the mechanics, but somehow installing
the kvm irqchip route for the dummy irq on the BCM5719 means that after EEH
reset and recovery, at least some irqs are no longer delivered to the
guest.
In particular, the guest never gets the link up event, and so the NIC is
effectively dead.
[1] EEH (Enhanced Error Handling) is an IBM POWER server specific PCI-*
error reporting and recovery mechanism. The concept is somewhat
similar to PCI-E AER, but the details are different.
