which are technically invalid ISO C, but GCC accepts as an extension.
If we added enough __extension__ markers that we could dare use

The x86 and ppc targets call cpu_synchronize_state() from their
*_cpu_dump_state() callbacks to ensure that up to date state is dumped
when KVM is enabled (for example when a KVM internal error occurs).
Move this call up into the generic cpu_dump_state() function so that
other KVM targets (namely MIPS) can take advantage of it.
This requires kvm_cpu_synchronize_state() and cpu_synchronize_state() to
be moved out of the #ifdef NEED_CPU_H in <sysemu/kvm.h> so that they're
accessible to qom/cpu.c.

But, it is not reasonable to convert them at one time
because fprintf() is used everwhere in qemu.

Commit 03a15a5436 claimed to add a POWER7+
model but instead added a "POWER7P" model, with an unhelpful "POWER7P"
description on top. Fix this to "POWER7+" as we already have "POWER3+",
"POWER4+" and "POWER5+" and there being no reason to deviate with the
user-visible command line -cpu POWER7P from the marketing name POWER7+.
Further, don't needlessly deviate from the scheme of naming PVR constant,
QOM type and device description after the exact revision that is in fact
encoded in the PVR used.
That way, we can change the user-friendly alias -cpu POWER7+ to point to a
different revision if we so desire, while not polluting the type namespace.
This naming scheme is sensible and completely orthogonal to how PVRs may
or may not get matched to CPU types.

Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code.
This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed".
The reason for the failure is that CPUClass::kvm_fd is not yet
initialized in the following call graph:
->x86_cpu_realizefn
->x86_cpu_apic_realize
->qdev_init
->device_set_realized
->device_reset (hotplugged == 1)
->apic_reset_common
->vapic_base_update
->kvm_apic_vapic_base_update
This causes attempted KVM vCPU ioctls to fail.
By contrast, in the non-hotplug case the APIC is reset much later, when
the vCPU is already initialized.
As a quick and safe solution, move the qemu_init_vcpu() call back into
the targets' realize functions.

Note from Alex regarding kvm_irqchip_create():
On x86, one would call kvm_irqchip_create() to initialize an

initializes global capability variables as well as the default irq

On ppc, we can't call kvm_irqchip_create() because we can have

The common KVM code insists on calling kvm_arch_init_irq_routing()
as soon as it sees kernel header support for it (regardless of whether
QEMU supports it). Provide a dummy function to satisfy this.
Unlike x86, PPC does not have one default irqchip, so there's no common
code that we'd stick here. Even if you ignore the routes themselves,
which even on x86 are not set up in this function, the initial XICS
kernel implementation will not support IRQ routing, so it's best to
leave even the general feature flags up to the specific irqchip code.

When running an L=1 cmp instruction on a 64bit PPC CPU with SF off, it
still behaves identical to what it does when SF is on. Remove the implicit
difference in the code.
Also, on most 32bit CPUs we should always treat the compare as 32bit
compare, as the CPU will ignore the L bit. This is not true for e500mc,
but that's up for a different patch.

When running -cpu on a POWER7 system with PR KVM, we mask out the 1TB
MMU capability from the MMU type mask, but not the AMR bit.
This leads to us having a new MMU type that we don't check for in our
MMU management functions.
Add the new type, so that we don't have to worry about breakage there.
We're not going to use the TCG MMU management in that case anyway.
The long term fix for this will be to move all these MMU management
functions to class callbacks.

Power ISA 2.05 adds support for extended mtfsf/mtfsfi form, with a new
W field to select the upper part of the FPCSR register.
For that the helper is changed to handle 64-bit input values and mask with
up to 16 bits. The mtfsf/mtfsfi instructions do not have the W bit
marked as invalid anymore. Instead this is checked in the helper, which
therefore needs to access to the insns/insns_flags2. They are added in
the DisasContext struct. Finally change all accesses to the opcode fields
through extract helpers, prefixed with FP for consistency.

For PAPR guests, KVM tracks the various areas registered with the
H_REGISTER_VPA hypercall. For full emulation, of course, these are tracked
within qemu. At present these values are not synchronized. This is a
problem for reset (qemu's reset of the VPA address is not pushed to KVM)
and will also be a problem for savevm / migration.
The kernel now supports accessing the VPA state via the ONE_REG interface,
this patch adds code to qemu to use that interface to keep the qemu and
KVM ideas of the VPA state synchronized.

In addition to the performance monitor registers found on nearly all
6xx chips, the POWER7 has two additional counters (PMC5 & PMC6) and an
extra control register (MMCRA). This patch adds stub support for them to
qemu - the registers won't do anything, but with this change won't cause
illegal instruction traps accessing them. They're also registered with
their ONE_REG ids, so their value will be kept in sync with KVM where
appropriate.

PAPR requires that the device tree's CPU nodes have several properties
with information about the L1 cache. We already create two of these
properties, but with incorrect names - "[id]cache-block-size" instead
of "[id]-cache-block-size" (note the extra hyphen).
We were also missing some of the required cache properties. This
patch adds the [id]-cache-line-size properties (which have the same
values as the block size properties in all current cases). We also
add the [id]-cache-size properties.
Adding the cache sizes requires some extra infrastructure in the
general target-ppc code to (optionally) set the cache sizes for
various CPUs. The CPU family descriptions in translate_init.c can set
these sizes - this patch adds correct information for POWER7, I'm
leaving other CPU types to people who have a physical example to
verify against. In addition, for -cpu host we take the values
advertised by the host (if available) and use those to override the
information based on PVR.

For the pseries machine, we need to advertise to the guest the size of its
RMA - that is the amount of memory it can access with the MMU off. For HV
KVM, this is constrained by the hardware limitations on the virtual RMA of
one hash PTE per PTE group in the hash page table. We already had code to
calculate this, but it was assuming the VRMA page size was the same as the
(host) backing page size for guest RAM.
In the case of a host kernel configured for 64k base page size, but running
on hardware (or firmware) which only allows 4k pages, the hose will do all
its allocations with a 64k page size, but still use 4k hardware pages for
actual mappings. Usually that's transparent to things running under the
host, but in the case of the maximum VRMA size it's not.
This patch refines the RMA size calculation to instead use the largest
available hardware page size (as reported by the SMMU_INFO call) which is
less than or equal to the backing page size. This now gives the correct
RMA size in all cases I've tested.

This patch may break support of some executables, as the power-on start

is different than HRESET vector (i.e. 0x00000100 or 0xfff00100), this

This value is not needed if we use correctly the MSR[IP] bit.
excp_prefix is always 0x00000000, except when the MSR[IP] bit is
implemented and set to 1, in that case excp_prefix is 0xfff00000.
The handling of MSR[IP] was already implemented but not used at reset
because the value of env->msr was changed "manually".
The patch uses the function hreg_store_msr() to set env->msr, this
ensures a good handling of MSR[IP] at reset, and therefore a good value
for excp_prefix.
