Most targets were using offsetof(CPUFooState, breakpoints) to determine
how much of CPUFooState to clear on reset. Use the next field after
CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise.

Note that while such functions may exist both for *-user and softmmu,
only *-user uses the CPUState hook, while softmmu reuses the prototype

Remove the custom qemu_assert() function defined by target-m68k/translate.c
in favour of either using glib g_assert_not_reached() (for the genuinely
can't-happen cases) or cpu_abort() (for the "this isn't implemented",
in line with other unimplemented cases in the target).
This has the benefit of silencing some clang warnings about
variables used while uninitialized (which are emitted because
clang can't figure out that qemu_assert(0, something) never
returns.

Register separate QOM types for each x86 CPU model.
This will allow management code to more easily probe what each CPU model
provides, by simply creating objects using the appropriate class name,
without having to restart QEMU.
This also allows us to eliminate the qdev_prop_set_globals_for_type()
hack to set CPU-model-specific global properties.
Instead of creating separate class_init functions for each class, I just
used class_data to store a pointer to the X86CPUDefinition struct for
each CPU model. This should make the patch shorter and easier to review.
Later we can gradually convert each X86CPUDefinition field to lists of
per-class property defaults.
The "host" CPU model is special, as the feature flags depend on KVM
being initialized. So it has its own class_init and instance_init
function, and feature flags are set on instance_init instead of
class_init.

When on KVM mode, enable x2apic by default on all CPU models.
Normally we try to keep the CPU model definitions as close as the real
CPUs as possible, but x2apic can be emulated by KVM without host CPU
support for x2apic, and it improves performance by reducing APIC access
overhead. x2apic emulation is available on KVM since 2009 (Linux
2.6.32-rc1), there's no reason for not enabling x2apic by default when
running KVM.

There isn't any kind of "registration" involved in cpu_x86_register()
anymore: it is simply looking up a CPU model name and loading the model
definition data into the X86CPU object. Rename it to x86_cpu_load_def()
to reflect what it does.

cpu->exit_request is part of the execution environment and should

The hdev_create() implementation in block/raw-posix.c is used by the
"host_device", "host_cdrom" and "host_floppy" protocol block drivers
together. Thus, any of the associated prefixes may occur and exactly one
should should be stripped, if it does (thus,
"host_device:host_cdrom:/dev/cdrom" is not shortened to "/dev/cdrom").

qcow2_open() causes writes when repairing an image with the dirty flag
set and when clearing autoclear flags. It shouldn't do this when another
qemu instance is still actively working on this image file.
One effect of the bug is that images may have a cleared dirty flag while
the migration source host still has it in use with lazy refcounts
enabled, so refcounts are not accurate and the dirty flag must remain
set.

Instead of manually building a list of all options from BDRVQcowState
values just reuse the options that were used to open the image.
qcow2_open() won't fully use all of the options in the QDict, but that's
okay.
This fixes all of the driver-specific options in qcow2, except for
lazy-refcounts, which was special cased before.
