ACPI: processor: Print more information when acpi_processor_evaluate_cst() fails

Some platforms have bogus _CST which might cause unexpectd behavior
in the CPU idle driver. Some bogus _CST might be unable to be
disassembled by acpica-tools due to broken format.

Print extra log if the _CST extraction/verification failes.

This can be used to help narrow down why the CPU idle driver fails
to behave as expected.

Merge tag 'acpi-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
"These eliminate significant AML processing overhead related to using
operation regions in system memory, update the ACPICA code in the
kernel to upstream revision 20200717 (including a fix to prevent
operation region reference counts from overflowing in some cases),
remove the last bits of the (long deprecated) ACPI procfs interface
and do some assorted cleanups.

Specifics:

- Eliminate significant AML processing overhead related to using
operation regions in system memory by reworking the management of
memory mappings in the ACPI code to defer unmap operations (to do
them outside of the ACPICA locks, among other things) and making
the memory operation reagion handler avoid releasing memory
mappings created by it too early (Rafael Wysocki).

- Update the ACPICA code in the kernel to upstream revision 20200717:

* Prevent operation region reference counts from overflowing in
some cases (Erik Kaneda).

* Replace one-element array with flexible-array (Gustavo A. R.
Silva).

- Fix ACPI PCI hotplug reference counting (Rafael Wysocki).

- Drop last bits of the ACPI procfs interface (Thomas Renninger).

- Drop some redundant checks from the code parsing ACPI tables
related to NUMA (Hanjun Guo).

- Avoid redundant object evaluation in the ACPI device properties
handling code (Heikki Krogerus).

- Avoid unecessary memory overhead related to storing the signatures
of the ACPI tables recognized by the kernel (Ard Biesheuvel).

- Add missing newline characters when printing module parameter
values in some places (Xiongfeng Wang).

- Update the link to the ACPI specifications in some places (Tiezhu
Yang).

- Use the fallthrough pseudo-keyword in the ACPI code (Gustavo A. R.
Silva).

- Drop redundant variable initialization from the APEI code (Colin
Ian King).

- Drop uninitialized_var() from the ACPI PAD driver (Jason Yan).

- Replace HTTP links with HTTPS ones in the ACPI code (Alexander A.
Klimov)"

Merge tag 'pm-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"These add ACPI support to the intel_idle driver along with an admin
guide document for it, add support for CPR (Core Power Reduction) to
the AVS (Adaptive Voltage Scaling) subsystem, add new hardware support
in a few places, add some new sysfs attributes, debugfs files and
tracepoints, fix bugs and clean up a bunch of things all over.

Specifics:

- Update the ACPI processor driver in order to export
acpi_processor_evaluate_cst() to the code outside of it, add ACPI
support to the intel_idle driver based on that and clean up that
driver somewhat (Rafael Wysocki).

- Add an admin guide document for the intel_idle driver (Rafael
Wysocki).

- Clean up cpuidle core and drivers, enable compilation testing for
some of them (Benjamin Gaignard, Krzysztof Kozlowski, Rafael
Wysocki, Yangtao Li).

- Fix reference counting of OPP (operating performance points) table
structures (Viresh Kumar).

- Add support for CPR (Core Power Reduction) to the AVS (Adaptive
Voltage Scaling) subsystem (Niklas Cassel, Colin Ian King,
YueHaibing).

- Add support for TigerLake Mobile and JasperLake to the Intel RAPL
power capping driver (Zhang Rui).

- Update cpufreq drivers:
- Add i.MX8MP support to imx-cpufreq-dt (Anson Huang).
- Fix usage of a macro in loongson2_cpufreq (Alexandre Oliva).
- Fix cpufreq policy reference counting issues in s3c and
brcmstb-avs (chenqiwu).
- Fix ACPI table reference counting issue and HiSilicon quirk
handling in the CPPC driver (Hanjun Guo).
- Clean up spelling mistake in intel_pstate (Harry Pan).
- Convert the kirkwood and tegra186 drivers to using
devm_platform_ioremap_resource() (Yangtao Li).

- Update devfreq core:
- Add 'name' sysfs attribute for devfreq devices (Chanwoo Choi).
- Clean up the handing of transition statistics and allow them to
be reset by writing 0 to the 'trans_stat' devfreq device
attribute in sysfs (Kamil Konieczny).
- Add 'devfreq_summary' to debugfs (Chanwoo Choi).
- Clean up kerneldoc comments and Kconfig indentation (Krzysztof
Kozlowski, Randy Dunlap).

- Update devfreq drivers:
- Add dynamic scaling for the imx8m DDR controller and clean up
imx8m-ddrc (Leonard Crestez, YueHaibing).
- Fix DT node reference counting and nitialization error code path
in rk3399_dmc and add COMPILE_TEST and HAVE_ARM_SMCCC dependency
for it (Chanwoo Choi, Yangtao Li).
- Fix DT node reference counting in rockchip-dfi and make it use
devm_platform_ioremap_resource() (Yangtao Li).
- Fix excessive stack usage in exynos-ppmu (Arnd Bergmann).
- Fix initialization error code paths in exynos-bus (Yangtao Li).
- Clean up exynos-bus and exynos somewhat (Artur Świgoń, Krzysztof
Kozlowski).

- Add tracepoints for tracking usage_count updates unrelated to
status changes in PM-runtime (Michał Mirosław).

- Add sysfs attribute to control the "sync on suspend" behavior
during system-wide suspend (Jonas Meurer).

- Switch system-wide suspend tests over to 64-bit time (Alexandre
Belloni).

- Make wakeup sources statistics in debugfs cover deleted ones which
used to be the case some time ago (zhuguangqing).

- Clean up computations carried out during hibernation, update
messages related to hibernation and fix a spelling mistake in one
of them (Wen Yang, Luigi Semenzato, Colin Ian King).

- Add mailmap entry for maintainer e-mail address that has not been
functional for several years (Rafael Wysocki)"
