"info mtree -f" output is currently hard to use for large RAM regions, because
there is no hint as to what part of the region is being mapped. Add the offset
if it is nonzero.
Secondly, FlatView has a readonly field, that can override the MemoryRegion
in the presence of aliases. Take it into account.
Together, with this patch this:

Migration from a 2.3.0 qemu results in a reboot on the receiving QEMU
due to a disagreement about SM (System management) interrupts.
2.3.0 didn't have much SMI support, but it did set CPU_INTERRUPT_SMI
and this gets into the migration stream, but on 2.3.0 it
never got delivered.
~2.4.0 SMI interrupt support was added but was broken - so
that when a 2.3.0 stream was received it cleared the CPU_INTERRUPT_SMI
but never actually caused an interrupt.
The SMI delivery was recently fixed by 68c6efe07a, but the
effect now is that an incoming 2.3.0 stream takes the interrupt it
had flagged but it's bios can't actually handle it(I think
partly due to the original interrupt not being taken during boot?).
The consequence is a triple(?) fault and a reboot.
Tested from:
2.3.1 -M 2.3.0
2.7.0 -M 2.3.0
2.8.0 -M 2.3.0
2.8.0 -M 2.8.0
This corresponds to RH bugzilla entry 1420679.

In 'qemu_chr_open_spice_vmc' if the 'psubtype' is NULL, it will
call 'char_spice_finalize'. But as the SpiceChardev is not inserted
in the 'spice_chars' list, the 'QLIST_REMOVE' will cause a segfault.
Add a detect to avoid it.

In commit af6bf1328ef90fae617857c02697e0174b84d596 (May 2011),
ide-hd, ide-cd and scsi-cd have been added to disable default cdrom,
"or else you can't put one on secondary master without -nodefaults".
Make it the same for scsi-hd, so you can put one on scsi-id 2 without
using -nodefaults.
scsi-hd has probably been forgotten, as it has been added in the
preceding commit (b443ae67130d32ad06b06fc9aa6d04d05ccd93ce).
Affected users are the ones using a machine with SCSI devices and start QEMU
with -device scsi-hd but without -device scsi-cd or -cdrom
In that case, the default cdrom device will disappear instead of being empty.

At the moment ram device's memory regions are DEVICE_NATIVE_ENDIAN. It's
incorrect. This memory region is backed by a MMIO area in host, so the
uint64_t data that MemoryRegionOps read from/write to this area should be
host-endian rather than target-endian. Hence, current code does not work
when target and host endianness are different which is the most common case
on PPC64. To fix it, this introduces DEVICE_HOST_ENDIAN for the ram device.
This has been tested on PPC64 BE/LE host/guest in all possible combinations
including TCG.

The purpose of the KVM_SET_SIGNAL_MASK API is to let userspace "kick"
a VCPU out of KVM_RUN through a POSIX signal. A signal is attached
to a dummy signal handler; by blocking the signal outside KVM_RUN and
unblocking it inside, this possible race is closed:
VCPU thread service thread
--------------------------------------------------------------
check flag
set flag
raise signal
(signal handler does nothing)
KVM_RUN
However, one issue with KVM_SET_SIGNAL_MASK is that it has to take
tsk->sighand->siglock on every KVM_RUN. This lock is often on a
remote NUMA node, because it is on the node of a thread's creator.
Taking this lock can be very expensive if there are many userspace
exits (as is the case for SMP Windows VMs without Hyper-V reference
time counter).
KVM_CAP_IMMEDIATE_EXIT provides an alternative, where the flag is
placed directly in kvm_run so that KVM can see it:
VCPU thread service thread
--------------------------------------------------------------
raise signal
signal handler
set run->immediate_exit
KVM_RUN
check run->immediate_exit
The previous patches changed QEMU so that the only blocked signal is
SIG_IPI, so we can now stop using KVM_SET_SIGNAL_MASK and sigtimedwait
if KVM_CAP_IMMEDIATE_EXIT is available.
On a 14-VCPU guest, an "inl" operation goes down from 30k to 6k on
an unlocked (no BQL) MemoryRegion, or from 30k to 15k if the BQL
is involved.

The cast is there because sigbus_handler is invoked via sigfd_handler.
But it feels just wrong to use struct qemu_signalfd_siginfo in the
prototype of a function that is passed to sigaction.
Instead, do a simple-minded conversion of qemu_signalfd_siginfo to
siginfo_t.

'remotes/dgibson/tags/submodule-update-20170303' into staging
submodule updates (SLOF & dtc) 2017-03-03
This set of patches updates the SLOF and dtc submodules for qemu-2.9.
The SLOF update could have gone in my ppc pull request earlier today,
but I forgot it. It should be safe to apply in either order with that
set though.
The dtc (and libfdt) update brings us up to dtc 1.4.3 which includes
some things that will be useful in future.

ppc patch queue for 2017-03-01
I was hoping to get this pull request squeezed in before the soft
freeze, but I ran into some difficulties during testing. Everything
here was at least posted before the soft freeze, so I'm hoping we can
still merge it for 2.9.
The biggest things here are:
* Cleanups to handling of hashed page tables, that will make
adding support for the POWER9 MMU easier
* Cleanups to the XICS interrupt controller that will make
implementing the powernv machine easier
* TCG implementation of extended overflow and carry handling for
POWER9
It also includes:
* Increasing the CPU limit for pseries to 1024 vCPUs
* Generating proper OF node names in qemu (making hotplug and
coldplug logic closer together)

Add the missing osc method for pxb-pcie devices as APCI spec recommends,
see 6.2.9.1 OSC Implementation Example for PCI Host Bridge Devices, ACPI 3.0a:
It is recommended that a machine with multiple host bridge devices
should report the same capabilities for all host bridges, and also
negotiate control of the features described in the Control Field in
the same way for all host bridges.

Commit c611c76417f5 ("virtio: add MemoryListener to cache ring
translations") registers a memory listener to dma_as. This may not
work when IOMMU is enabled: dma_as(bus_master_as) were initialized in
pcibus_machine_done() after virtio_realize(). This will cause a
segfault. Fixing this by using pci_device_iommu_address_space()
instead to make sure address space were initialized at this time.
With this fix, IOMMU device were required to be initialized before any
virtio-pci devices.

Commit 97cd965c070152bc626c7507df9fb356bbe1cd81 ("virtio: use
VRingMemoryRegionCaches for avail and used rings") switched to a memory
region cache to avoid repeated map/unmap operations.
The virtio_load() process is a little tricky because vring addresses are
serialized in two separate places. VIRTIO 1.0 devices serialize desc
and then a subsection with used and avail. Legacy devices only
serialize desc.
Live migration of VIRTIO 1.0 devices fails on the destination host with:
VQ 0 size 0x80 < last_avail_idx 0x12f8 - used_idx 0x0
Failed to load virtio-blk:virtio
error while loading state for instance 0x0 of device '0000:00:04.0/virtio-blk'
This happens because the memory region cache is only initialized after
desc is loaded and not after the used and avail subsection is loaded.
If the guest chose memory addresses that don't match the legacy ring
layout then the wrong guest memory location is accessed.
Wait until all ring addresses are known before trying to initialize the
region cache. Also clarify the incomplete comment about VIRTIO-1 ring
address subsection.

Switching to vring caches exposed an existing bug in
virtio_queue_set_notification(): We can't access vring structures
if they have not been set up yet. This may happen, for example,
for virtio-blk devices with multiple queues: The code will try to
switch notifiers for every queue, but the guest may have only set up
a subset of them.
Fix this by guarding access to the vring memory by checking for
vring.desc. The first aio poll will iron out any remaining
inconsistencies for later-configured queues (buggy legacy drivers).

If the vring has not been set up, there is nothing in the virtqueue.
virtio_queue_host_notifier_aio_poll calls virtio_queue_empty even in
this case; we have to filter it out just like virtio_queue_notify_aio_vq.
