It using map_domain_page() was entirely wrong. Use __acpi_map_table()
instead for the time being, with locking added as the mappings it
produces get replaced with subsequent invocations. Using locking in
this way is acceptable here since the only two runtime callers are
acpi_os_{read,write}_memory(), which don't leave mappings pending upon
returning to their callers.
Also fix __acpi_map_table()'s first parameter's type - while benign for
unstable, backports to pre-4.3 trees will need this.

In order to have Dom0 call _PDC with input fully representing Xen's
capabilities, and in order to avoid building knowledge of Xen
implementation details into Dom0, this provides a mechanism by which
the Dom0 kernel can, once it filled the _PDC input buffer according to
its own knowledge, present the buffer to Xen to apply overrides for
the parts of the C-, P-, and T-state management that it controls. This
is particularly to address the dependency of Xen using MWAIT to enter
certain C-states on the availability of the break-on-interrupt
extension (which the Dom0 kernel should have no need to know about).

There are two sets of ACPI table enums and structs, and clang
complains about implicit casts between them. It would be much better
to remove one entire set of ACPI definitions but for now just use the
right enum for each interface.

APEI are ACPI4.0 new features. It consists of ERST, BERT, HEST, and
EINJ. ERST is used to save fault error log to a platform persistent
storage, so that when reboot os can retrieve the error log and handle
it.
This patch is used to implement ERST feature to Xen. It consists of
3-level hierarchy: operation level, action level, and instru= ction
level. Instruction do basic io; Action done by sequential
instructions parsed from ACPI ERST table; Operation done by
sequential actions defined by ACPI spec, providing erst_write/
erst_read/ erst_clear interfaces to MCE/ NMI/ PCIe error handling
mechanism, etc.

All logical processors with APIC ID values of 255 and greater will
have their APIC reported through Processor X2APIC structure (type-9
entry type) and all logical processors with APIC ID less than 255 will
have their APIC reported through legacy Processor Local APIC (type-0
entry type) only. This is the same case even for NMI structure
reporting.
The Processor X2APIC Affinity structure provides the association
between the X2APIC ID of a logical processor and the proximity domain
to which the logical processor belongs.
This patch adds 2 new subtables to MADT and one new subtable to SRAT.
This patch also changes x86_acpiid_to_apicid from u8 to u32 for x2APIC
ID, and changes mp_register_lapic to accept 32-bit id. But there are
still some 8-bit apic id hardcode and assumptions in Xen code, it
needs to be fixed in future.

Introduces a virtual space conserving transformation on the MFN thus
far used to index 1:1 mapping and frame table, removing the largest
range of contiguous bits (below the most significant one) which are
zero for all valid MFNs from the MFN representation, to be used to
index into those arrays, thereby cutting the virtual range these
tables must cover approximately by half with each bit removed.
Since this should account for hotpluggable memory (in order to not
requiring a re-write when that gets supported), the determination of
which bits are candidates for removal must not be based on the E820
information, but instead has to use the SRAT. That in turn requires a
change to the ordering of steps done during early boot.

Remove ASSERT(spin_is_locked(&pcidevs_lock)) in
pci_get_pdev_by_domain() to allow caller the flexibility to not hold
the lock if it does not care if the device is hot removed between the
time it got the pdev and the time it is used to get the corresponding
vt-d engine. In the new RHSA use case, we just wanted to get the vt-d
engine of any device passthrough in the domain. Also, rename RHSA
field "domain" to "proximity domain" to avoid overloading the term
"domain" in virtualization context.

This patch adds VT-d RHSA processing for IO NUMA support. The basic
idea is to parse ACPI RHSA structure to obtain VT-d HW to proximity
domain mapping. This mapping is then used when allocating pages for
Vt-d HW data structures.

This is to properly handle SRAT rev 2 extended proximity domain

Also a first step to eliminate the redundant definitions of

Some AMD machines have APIC IDs that not equal to CPU IDs. In
the default Xen configuration, ACPI calls on these machines
can get confused. This shows up most noticeably when running
AMD PowerNow!. The only solution is for dom0 to get the
hypervisor's cpuid to apicid table when needed (ie, when dom0
vcpus are pinned).
Add a vcpu op to Xen to allow dom0 to query the hypervisor for
architecture dependent physical cpu information if dom0 vcpus are
pinned.

Our IPF machines are the following configurations.
- Total logical cpus = 16
-- 4 sockets
-- 2 cores
-- 2 threads
I changed the setting of BIOS, and invalidated the hyperthread, and I built Xen with NR_CPUS=8.
As a result, it became like attached file xendmesg1.txt.
- Available cpus 3
- Total cpus 8
Next, I built Xen with NR_CPUS=16.
As a result, it became like attached file xendmesg2.txt.
- Available cpus 8
- Total cpus 16
I thought not to match the analysis of the lsapic entry to the value of NR_CPUS.
It is an outline of patch as follows.
1. Count up the lsapic entry by using acpi_table_count_madt()/acpi_table_count_madt_family().
2. Call acpi_parse_lsapic() by using the number of lsapic entries.
3. Count up the available_cpus by using acpi_parse_lsapic(), however NR_CPUS is not exceeded.
