This commit was generated mechanically by coccinelle from the following
semantic patch:

@@
expression val;
@@
- (ffs(val) - 1)
+ ctz32(val)

The call sites have been audited to ensure the ffs(0) - 1 == -1 case
never occurs (due to input validation, asserts, etc).  Therefore we
don't need to worry about the fact that ctz32(0) == 32.

19fff2d405 acpi: include PkgLength size only when requested
Named/Reserved{Field} definition uses PkgLength [1] encoding to specify
field length, however it doesn't include size of PkgLength field itself,
while other block objects that have explicit length of its body account
for PkgLength size while encoding it [2].
This special casing isn't mentioned in ACPI spec, but that's what 'iasl'
compiles NamedField to so add extra argument to build_prepend_pkg_length()
to allow it handle the case.

0f2707e4e7 acpi: introduce AML composer aml_append()
Adds for dynamic AML creation, which will be used
for piecing ASL/AML primitives together and hiding
from user/caller details about how nested context
should be closed/packed leaving less space for
mistakes and necessity to know how AML should be
encoded, allowing user to concentrate on ASL
representation instead.

For example it will allow to create AML like this:

init_aml_allocator();
...
Aml *scope = aml_scope("PCI0")
Aml *dev = aml_device("PM")
    aml_append(dev, aml_name_decl("_ADR", aml_int(addr)))
aml_append(scope, dev);
...

6ac0d8d44c ich9: add disable_s3, disable_s4, s4_val properties
PIIX4 has disable_s3 and disable_s4 properties to enable or disable PM
functions.  Add such properties to the ICH9 chipset as well for the Q35
machine type.

S3 / S4 are not guaranteed to always work (needs work in the guest as
well as QEMU for things to work properly), and disabling advertising of
these features ensures guests don't go into zombie state if something
isn't working right.

The defaults are kept the same as in PIIX4: both S3 and S4 are enabled
by default.

These can be disabled via the cmdline:

  ... -global ICH9-LPC.disable_s3=1 -global ICH9-LPC.disable_s4=1

Note: some guests can fake hibernation by writing a hibernate image and
doing a shutdown instead of S4 if S4 isn't available; there's nothing we
can do guests to stop doing this, and this patch can't affect that
functionality.

91ab2ed722 pc: piix4_pm: init legacy PCI hotplug when running on Xen
If user starts QEMU with "-machine pc,accel=xen", then
compat property in xenfv won't work and it would cause error:
"Unsupported bus. Bus doesn't have property 'acpi-pcihp-bsel' set"
when PCI device is added with -device on QEMU CLI.

From: Igor Mammedov <imammedo@redhat.com>

In case of Xen instead of using compat property, just use the fact
that xen doesn't use QEMU's fw_cfg/acpi tables to switch piix4_pm
into legacy PCI hotplug mode when Xen is enabled.

d49805aeea savevm: Remove all the unneeded version_minimum_id_old (x86)
After previous Peter patch, they are redundant.  This way we don't
assign them except when needed.  Once there, there were lots of case
where the ".fields" indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

7c38ecd097 acpi/pcihp.c: Rewrite acpi_pcihp_get_bsel using object_property_get_int
acpi_pcihp_get_bsel implements functionality of object_property_get_int for
specific property named ACPI_PCIHP_PROP_BSEL, but fails to decrement object's
reference counter properly. Rewriting it using generic object_property_get_int
serves two purposes: reducing code duplication and fixing memory leak.

AcpiCpuHotplug_add() can't handle vCPU arch IDs larger than
ACPI_CPU_HOTPLUG_ID_LIMIT. Instead of corrupting memory in case the vCPU
ID is too large, use g_assert() to ensure we are not over the limit.
