A bunch of fixes that missed the release.
 Most notably we are reverting shpc back to enabled by default state
 as guests uses that as an indicator that hotplug is supported
 (even though it's unused). Unfortunately we can't fix this
 on the stable branch since that would break migration.

He Chen 0f203430dd numa: Allow setting NUMA distance for different NUMA nodes
This patch is going to add SLIT table support in QEMU, and provides
additional option `dist` for command `-numa` to allow user set vNUMA
distance by QEMU command.

With this patch, when a user wants to create a guest that contains
several vNUMA nodes and also wants to set distance among those nodes,
the QEMU command would like:

```
-numa node,nodeid=0,cpus=0 \
-numa node,nodeid=1,cpus=1 \
-numa node,nodeid=2,cpus=2 \
-numa node,nodeid=3,cpus=3 \
-numa dist,src=0,dst=1,val=21 \
-numa dist,src=0,dst=2,val=31 \
-numa dist,src=0,dst=3,val=41 \
-numa dist,src=1,dst=2,val=21 \
-numa dist,src=1,dst=3,val=31 \
-numa dist,src=2,dst=3,val=21 \
```

Ard Biesheuvel cb51ac2ffe hw/arm/virt: generate 64-bit addressable ACPI objects
Our current ACPI table generation code limits the placement of ACPI
tables to 32-bit addressable memory, in order to be able to emit the
root pointer (RSDP) and root table (RSDT) using table types from the
ACPI 1.0 days.

Since ARM was not supported by ACPI before version 5.0, it makes sense
to lift this restriction. This is not crucial for mach-virt, which is
guaranteed to have some memory available below the 4 GB mark, but it
is a nice to have for QEMU machines that do not have any 32-bit
addressable memory, which is not uncommon for real world 64-bit ARM
systems.

Since we already emit a version of the RSDP root pointer that has a
secondary 64-bit wide address field for the 64-bit root table (XSDT),
all we need to do is replace the RSDT generation with the generation
of an XSDT table, and use a different slot in the FADT table to refer
to the DSDT.

Ben Warren c7809e6cd7 ACPI: Add vmgenid blob storage to the build tables
This allows them to be centrally initialized and destroyed

The "AcpiBuildTables.vmgenid" array will be used to construct the
"etc/vmgenid_guid" fw_cfg blob.

Its contents will be linked into fw_cfg after being built on the
pc_machine_done() -> acpi_setup() -> acpi_build() call path, and dropped
without use on the subsequent, guest triggered, acpi_build_update() ->
acpi_build() call path.

Igor Mammedov 28213cb6a6 acpi: make bios_linker_loader_add_checksum() API offset based
It should help to make clear that bios_linker works in terms
of offsets within a file. Also it should prevent mistakes
where user passes as arguments pointers to unrelated to file blobs.

While at it, considering that it's a ACPI checksum and
it's initial value must be 0, move checksum field zeroing
into bios_linker_loader_add_checksum() instead of doing it
at every call site manually before bios_linker_loader_add_checksum()
is called.

In addition add extra boundary checks.

Igor Mammedov ad9671b870 acpi: simplify bios_linker API by removing redundant 'table' argument
'table' argument in bios_linker_add_foo() commands is
a data blob of one of files also passed to the same API.
So instead of passing blob in every API call, add and keep
file name association with related blob at bios_linker_loader_alloc()
time.

And find blob by name looking up allocated file entries
inside of bios_linker_add_foo() commands.

It will:
 - make API less confusing,
 - enforce calling bios_linker_loader_alloc() before
   calling any bios_linker_add_foo()
 - make sure that blob is the correct one, i.e.
   associated with the right file name

Igor Mammedov 20ca520884 acpi: extend aml_add() to accept target argument
it allows to express following ASL expression:
 Add(arg1, arg2, result)

usecases that do not need to store result
should pass NULL as 3rd arg that would express
 Add(arg1, arg2,)
construct.

Igor Mammedov 439e2a6e10 acpi: aml: add helper for Opcode Arg2 Arg2 [Dst] AML pattern
Currently AML API doesn't compose terms in form of
following pattern:

   Opcode Arg2 Arg2 [Dst]

but ASL used in piix4/q35 DSDT ACPI tables uses that
form, so for clean conversion of it, AML API should
be able to handle an optional 'Dst' argumet used there.

Since above pattern is used by arithmetic/bit ops,
introduce helper that they could reuse.
It reduces code duplication in existing 5 aml_foo()
functions and also will prevent more duplication
when exiting functions are extended to support
optional 'Dst' argument.
