Merge ACPI device enumeration changes and ACPI data-only tables support
updates for 6.10:

computations from container_of() in some cases (Andy Shevchenko).
- Do some assorted cleanups of the ACPI device enumeration code (Andy
Shevchenko).
- Make the ACPI device enumeration code skip devices with _STA values
clearly identified by the specification as invalid (Rafael Wysocki).

For configurations that have the kconfig option NUMA_KEEP_MEMINFO
disabled, numa_fill_memblks() only returns with NUMA_NO_MEMBLK (-1).
SRAT lookup fails then because an existing SRAT memory range cannot be
found for a CFMWS address range. This causes the addition of a
duplicate numa_memblk with a different node id and a subsequent page
fault and kernel crash during boot.
Fix this by making numa_fill_memblks() always available regardless of
NUMA_KEEP_MEMINFO.
As Dan suggested, the fix is implemented to remove numa_fill_memblks()
from sparsemem.h and alos using __weak for the function.
Note that the issue was initially introduced with [1]. But since
phys_to_target_node() was originally used that returned the valid node
0, an additional numa_memblk was not added. Though, the node id was
wrong too, a message is seen then in the logs:
kernel/numa.c: pr_info_once("Unknown target node for memory at 0x%llx, assuming node 0\n",

Commit 54ce1927eb78 ("cxl/cper: Fix errant CPER prints for CXL events")
moved the CXL CPER section defines to include/linux/cper.h from ghes.c
When the latest cxl/cper series was reworked those defines were kept in
ghes.c by accident. Thus they were duplicated.
Delete the duplicate defines keeping them in the header to be shared

BIOS can configure memory devices as firmware first. This will send CXL
events to the firmware instead of the OS. The firmware can then inform
the OS of these events via UEFI.
UEFI v2.10 section N.2.14 defines a Common Platform Error Record (CPER)
format for CXL Component Events. The format is mostly the same as the
CXL Common Event Record Format. The difference lies in the use of a
GUID as the CPER Section Type which matches the UUID defined in CXL 3.1
Table 8-43.
Currently a configuration such as this will trace a non standard event
in the log omitting useful details of the event. In addition the CXL
sub-system contains additional region and HPA information useful to the
user.[0]
The CXL code is required to be called from process context as it needs
to take a device lock. The GHES code may be in interrupt context. This
complicated the use of a callback. Dan Williams suggested the use of
work items as an atomic way of switching between the callback execution
and a default handler.[1]
The use of a kfifo simplifies queue processing by providing lock free
fifo operations. cxl_cper_kfifo_get() allows easier management of the
kfifo between the ghes and cxl modules.
CXL 3.1 Table 8-127 requires a device to have a queue depth of 1 for
each of the four event logs. A combined queue depth of 32 is chosen to
provide room for 8 entries of each log type.
Add GHES support to detect CXL CPER records. Add the ability for the
CXL sub-system to register a work queue to process the events.
This patch adds back the functionality which was removed to fix the
report by Dan Carpenter[2].

The return value of _STA with the "present" bit unset and the "enabled"
bit set is clearly invalid as per the ACPI specification, Section 6.3.7
"_STA (Device Status)", so make the ACPI device enumeration code
disregard devices with such _STA return values.
Also, because this implies that status.enabled will only be set if
status.present is set too, acpi_device_is_enabled() can be modified
to simply return the value of the former.

On Dell servers, many APCI methods of acpi_power_meter module evaluate
variables inside IPMI region, so the region handler needs to be
installed. In addition to that, the handler needs to be fully
functional, and that depends on SMI being selected.
So add a helper to let acpi_power_meter know when the handler is
installed and ready to be used.

commit 2f4a4d63a193 ("ACPI: CPPC: Use access_width over bit_width for system
memory accesses") modified cpc_read()/cpc_write() to use access_width to
read CPC registers.
However, for PCC registers the access width field in the ACPI register
macro specifies the PCC subspace ID. For non-zero PCC subspace ID it is
incorrectly treated as access width. This causes errors when reading
from PCC registers in the CPPC driver.
For PCC registers, base the size of read/write on the bit width field.
The debug message in cpc_read()/cpc_write() is updated to print relevant
information for the address space type used to read the register.

Add support for the tpiu device in the platform driver, which can then be
used on ACPI based platforms. This change would now allow runtime power
management for ACPI based systems. The driver would try to enable the APB
clock if available. But first this renames and then refactors tpiu_probe()
and tpiu_remove(), making sure it can be used both for platform and AMBA
drivers. This also moves pm_runtime_put() from tpiu_probe() to the callers.
While here, this also sorts the included headers in alphabetic order.

Deduplicate ->read() callbacks of bin_attributes which are backed by a
simple buffer in memory:
Use the newly introduced sysfs_bin_attr_simple_read() helper instead,
either by referencing it directly or by declaring such bin_attributes
with BIN_ATTR_SIMPLE_RO() or BIN_ATTR_SIMPLE_ADMIN_RO().
Aside from a reduction of LoC, this shaves off a few bytes from vmlinux
(304 bytes on an x86_64 allyesconfig).

a memcpy(), but turning the warning off for this file works equally well
and may be easier to merge.

The x86 Android tablets on which quirks to skip looking for a matching
UartSerialBus resource and instead unconditionally create a serial bus
device (serdev) are necessary there are 2 sorts of serialports:
ACPI enumerated highspeed designware UARTs, these are the ones which
typcially need to be skipped since they need a serdev for the attached
BT HCI.
A PNP enumerated UART which is part of the PCU. So far the existing
quirks have ignored this. But on the Lenovo Yoga Tablet 2 Pro 1380
models this is used for a custom fastcharging protocol. There is
a Micro USB switch which can switch the USB data lines to this uart
and then a 600 baud protocol is used to configure the charger for
a voltage higher then 5V.
Add a new ACPI_QUIRK_PNP_UART1_SKIP quirk type and set this for
the existing entry for the Lenovo Yoga Tablet 2 830 / 1050 models.
Note this will lead to unnecessarily also creating a serdev for
the PCU UART on the 830 / 1050 which don't need this, but the UART
is not used otherwise there so that is not a problem.

On the Toshiba Encore WT10-A tablet the BATC battery ACPI device depends
on 3 other devices:
Name (_DEP, Package (0x03) // _DEP: Dependencies
{
I2C1,
GPO2,
GPO0
})
acpi_scan_check_dep() adds all 3 of these to the acpi_dep_list and then
before an acpi_device is created for the BATC handle (and thus before
acpi_scan_dep_init() runs) acpi_scan_clear_dep() gets called for both
GPIO depenencies, with free_when_met not set for the dependencies.
Since there is no adev for BATC yet, there also is no dep_unmet to
decrement. The only result of acpi_scan_clear_dep() in this case is
dep->met getting set.
Soon after acpi_scan_clear_dep() has been called for the GPIO dependencies
the acpi_device gets created for the BATC handle and acpi_scan_dep_init()
runs, this sees 3 dependencies on the acpi_dep_list and initializes
unmet_dep to 3. Later when the dependency for I2C1 is met unmet_dep
becomes 2, but since the 2 GPIO deps where already met it never becomes 0
causing battery monitoring to not work.
Fix this by modifying acpi_scan_dep_init() to not increase dep_met for
dependencies which have already been marked as being met.
