Use the ACPI table construction tools to create an ACPI entry
for IPMI. This adds a function called build_acpi_ipmi_devices
to add an DSDT entry for IPMI if IPMI is compiled in and an
IPMI device exists. It also adds a dummy function if IPMI
is not compiled in.
This conforms to section "C3-2 Locating IPMI System Interfaces in
ACPI Name Space" in the IPMI 2.0 specification.

This fix SID verification failure when IOMMU IR is enabled with PCI
bridges. Existing pci_requester_id() is more like getting BDF info
only. Renaming it to pci_get_bdf(). Meanwhile, we provide the correct
implementation to get requester ID. VT-d spec 5.1.1 is a good reference
to go, though it talks only about interrupt delivery, the rule works
exactly the same for non-interrupt cases.
Currently, there are three use cases for pci_requester_id():
- PCIX status bits: here we need BDF only, not requester ID. Replacing
with pci_get_bdf().
- PCIe Error injection and MSI delivery: for both these cases, we are
looking for requester IDs. Here we should use the new impl.
To avoid a PCI walk every time we send MSI message, one requester_id
cache field is added to PCIDevice to cache the result when initialize
PCI device.

In legacy cpu-hotplug ProcessorID == APIC ID is used
in MADT and cpu-hotplug AML. It was fine as both
are 8bit and unique. Spec depricated Processor()
with corresponding ProcessorID and advises to use
Device() and UID instead of it.
However UID is just 32bit and it can't fit ARM's
arch_id(MPIDR) which is 64bit. Also in case of
sparse arch_id() distribution, managment/lookup
of maps by arch_id(APIC ID/MPIDR) becomes complex
and expensive.
In preparation to common CPU hotplug with ARM
and to simplify lookup in possible_cpus[] map
switch ProcessorID to possible_cpus index in
MADT.
Legacy cpu-hotplug considerations:
HW interface of it is APIC ID based bitmask so
it's impossible to change, also CPON package in
AML also APIC ID based as well all the methods.
To avoid massive rewrite of AML keep is so and
just break assumption that ProcessorID == APIC ID,
ammending CPU_MAT_METHOD to accept APIC ID and
possible_cpus index, it needs them both to patch
MADT entry template. Also switch to possible_cpus
index Processor(ProcessorID) AML.
That way changes to MADT/AML are minimal and kept
inside AML/MADT not affecting external interfaces.

This patch extends the functionality of the max-ram-below-4g option

While being at it also rework the lowmem calculation logic and add a
longish comment describing how it works and what the compatibility
constrains are.
Note: This is a incompatible change. When setting max-ram-below-4g to
a value larger than 3.5G (or 3G with gigabyte alignment) it has no
effect on older qemu versions: qemu silently ignores it. With the patch
applied it actually has an effect and changes the ram layout. Highly

IRQ 5 used by TPM conflicts with PNP0C0F IRQs,
as result Windows fails driver initialization with reason
'device cannot find enough free resources'
But if TPM._CRS.IRQ entry is commented out, Windows
seems to initialize driver without errors as it doesn't
notice possible conflict and it seems to work
probably due to a link with IRQ 5 being unused/disabled.
So temporary comment out TPM._CRS.IRQ to 'fix'

2. fetch IRQ value from device model so that user

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h

possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.
