Threads within a core shouldn't be on different
NUMA nodes, so if user has misconfgured command
line, fail QEMU at start up to force user fix it.

For now use the first thread on the core as source
of core's node-id. Later when cpu-numa refactoring
lands  it will be switched to core's node-id from
possible_cpus[].

This prevents the same problems as commit 20bb648d

The recent changes on the XICS layer removed the XICSState object to
let the sPAPR machine handle the ICP and ICS directly. The reset of
these objects was previously handled by XICSState, which was a SysBus
device, and to keep the same behavior, the ICP and ICS were assigned
to SysbBus.

But that broke the 'info qtree' command in the monitor. 'qtree'
performs a loop on the children of a bus to print their properties and
SysBus devices are expected to be found under SysBus, which is not the
case anymore.

The fix for this problem is to register reset handlers for the ICP and
ICS objects and stop using SysBus for such devices.

ppc patch queuye for 2017-03-03

This will probably be my last pull request before the hard freeze.  It
has some new work, but that has all been posted in draft before the
soft freeze, so I think it's reasonable to include in qemu-2.9.

This batch has:
    * A substantial amount of POWER9 work
        * Implements the legacy (hash) MMU for POWER9
	* Some more preliminaries for implementing the POWER9 radix
          MMU
	* POWER9 has_work
	* Basic POWER9 compatibility mode handling
	* Removal of some premature tests
    * Some cleanups and fixes to the existing MMU code to make the
      POWER9 work simpler
    * A bugfix for TCG multiply adds on power
    * Allow pseries guests to access PCIe extended config space

This also includes a code-motion not strictly in ppc code - moving
getrampagesize() from ppc code to exec.c.  This will make some future
VFIO improvements easier, Paolo said it was ok to merge via my tree.

"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 68c6efe0, 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

In commit af6bf132 (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 (b443ae67).

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

The SLOF update could have gone in my ppc pull request earlier today,

Commit 077dd742 inadvertently downgraded the 'dtc' submodule,
undoing the increment added in commit 6e85fce0. Revert this,
returning the submodule state to where we should be.

virtio, pc: fixes, features

virtio support for region caches broke a bunch of stuff - fixing most of
it though it's not ideal.  Still pondering the right way to fix it.
New: VM gen ID and hotplug for PXB.

Since the last submodule update (which was v1.4.2) dtc and libfdt have
gained some features which would be useful in qemu.  There's now a v1.4.3
upstream release, so update our submodule to point to it.

The PPC MMU types are sometimes treated as if they were a bit field
and sometime as if they were an enum which causes maintenance
problems: flipping bits in the MMU type (which is done on both the 1TB
segment and 64K segment bits) currently produces new MMU type
values that are not handled in every "switch" on it, sometimes causing
an abort().

This patch provides some macros that can be used to filter out the
"bit field-like" bits so that the remainder of the value can be
switched on, like an enum. This allows removal of all of the
"degraded" types from the list and should ease maintenance.

The (paravirtual) PCI host bridge on the 'pseries' machine in most
regards acts like a regular PCI bus, rather than a PCIe bus.  Despite
this, though, it does allow access to the PCIe extended config space.

We already implemented the RTAS methods to allow this access.. but
forgot to put the markers into the device tree so that guest's know it
is there.  This adds them in.

With this, a pseries guest is able to view extended config space on
(for example an e1000e device.  This should be enough to allow guests
to use at least some PCIe devices.

The hash mmu page fault handling code is responsible for generating ISIs
and DSIs when access permissions cause an access to fail. Part of this
involves setting the srr1 or dsisr registers to indicate what causes the
access to fail. Add defines for the bit fields of these registers and
rework the code to use these new defines in order to improve readability
and code clarity.

While we're here, update what is logged when an access fails to include
information as to what caused to access to fail for debug purposes.
