Commit 40f1ee27aa introduced handy helpers for enable_cap calls on
vcpu and vm level. Unfortunately some older gcc versions (4.7.1, 4.6)
seem to choke on signedness detection in inline created variables:
target-ppc/kvm.c: In function 'kvmppc_booke_watchdog_enable':
target-ppc/kvm.c:1302:21: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]
target-ppc/kvm.c: In function 'kvmppc_set_papr':
target-ppc/kvm.c:1504:21: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]
However - thanks to Thomas Huth for the suggestion - we can just cast the
offending potentially 0 value to a signed type, making the comparison signed.

Now that we have a CPU object with a reset method, it is better to
keep the KVM reset close to the CPU reset. Using qemu_register_reset
as we do now keeps them far apart.
With this patch, PPC no longer calls the kvm_arch_ function, so
it can get removed there. Other arches call it from their CPU
reset handler, and the function gets an ARMCPU/X86CPU/S390CPU.
Note that ARM- and s390-specific functions are called kvm_arm_*
and kvm_s390_*, while x86-specific functions are called kvm_arch_*.
That follows the convention used by the different architectures.
Changing that is the topic of a separate patch.

As suffixes do not make sense for sPAPR's device tree and
there is no way to filter them out on the BusState::get_fw_dev_path()
level, let's add an ability for the external caller to specify
whether to apply suffixes or not.
We could handle suffixes in SLOF (ignored for now) but this would require
serious rework in the node opening code in SLOF, which has no obvious
benefit for the currently emulated sPAPR machine.

The IOThread object is an AioContext event loop thread. This patch adds
the concept of multiple event loop threads, allowing users to define
them.
When SMP guests run on SMP hosts it makes sense to instantiate multiple
IOThreads. This spreads event loop processing across multiple cores.
Note that additional patches are required to actually bind a device to
an IOThread.

a typedef on the same struct twice.
To work around that limitation, let's extract the QEMUMachine typedef into a
separate header file that is guarded by preprocessor duplicate include checks.
This fixes the following type of compile errors for me:
In file included from vl.c:125:
include/hw/xen/xen.h:39: error: redefinition of typedef "QEMUMachine"
include/sysemu/kvm.h:155: error: previous declaration of "QEMUMachine" was here

functions are used to write 1st and 2nd dump_bitmap of kdump-compressed format,
which is used to indicate whether the corresponded page is existed in vmcore.
1st and 2nd dump_bitmap are same, because dump level is specified to 1 here.

the functions are used to write header of kdump-compressed format to vmcore.

flatten format will be used when writing kdump-compressed format. The format is
also used by makedumpfile, you can refer to the following URL to get more
detailed information about flatten format of kdump-compressed format:
http://sourceforge.net/projects/makedumpfile/
The two functions here are used to write start flat header and end flat header
to vmcore, and they will be called later when flatten format is used.
struct MakedumpfileHeader stored at the head of vmcore is used to indicate the
vmcore is in flatten format.
struct MakedumpfileHeader {
char signature[16]; /* = "makedumpfile" */
int64_t type; /* = 1 */
int64_t version; /* = 1 */
};
And struct MakedumpfileDataHeader, with offset and buf_size set to -1, is used
to indicate the end of vmcore in flatten format.
struct MakedumpfileDataHeader {
int64_t offset; /* = -1 */
int64_t buf_size; /* = -1 */
};

In order to allow the user to choose the framebuffer for sparc-softmmu, add
-vga tcx and -vga cg3 options to the QEMU command line. If no option is
specified, the default TCX framebuffer is used.
Since proprietary FCode ROMs use a resolution of 1152x900, slightly relax the
validation rules to allow both displays to be initiated at the higher
resolution used by these ROMs upon request (OpenBIOS FCode ROMs default to
the normal QEMU sun4m default resolution of 1024x768).
Finally move any fprintf(stderr ...) statements in the areas affected by this
patch over to the new error_report() function.

Introduces two simple functions:
int kvm_device_ioctl(int fd, int type, ...);
int kvm_create_device(KVMState *s, uint64_t type, bool test);
These functions wrap the basic ioctl-based interactions with KVM in a
way similar to other KVM ioctl wrappers.
