making it sound like it was fixing an actual bug. This is not the case.
The commit fixes a side issue discovered while investigating bug
#200011. It does NOT fix bug #200011 itself (as explicitly reported by
Jean-Marc at https://bugzilla.kernel.org/show_bug.cgi?id=200011#c65 ).
It does however cause regressions, despite what the commit message says. See:
https://bugzilla.kernel.org/show_bug.cgi?id=201721
and I expect more similar regressions, as ACPI resource conflicts are
very frequent.
This commit was not stable material to start with. It is intrusive,
presents a risk of side effects, and does not solve an actual bug that
is bothering users.

commit 3fa58dcab50a0aa16817f16a8d38aee869eb3fb9 upstream.
When the platform BIOS is unable to report all the media error records
it requires the OS to restart the scrub at a prescribed location. The
driver detects the overflow condition, but then fails to report it to
the ARS state machine after reaping the records. Propagate -ENOSPC
correctly to continue the ARS operation.

commit e8a308e5f47e545e0d41d0686c00f5f5217c5f61 upstream.
The NFIT machine check handler uses the physical address from the mce
structure, and compares it against information in the ACPI NFIT table
to determine whether that location lies on an NVDIMM. The mce->addr
field however may not always be valid, and this is indicated by the
MCI_STATUS_ADDRV bit in the status field.
Export mce_usable_address() which already performs validation for the
address, and use it in the NFIT handler.

commit 5d96c9342c23ee1d084802dcf064caa67ecaa45b upstream.
The MCE handler for nfit devices is called for memory errors on a
Non-Volatile DIMM and adds the error location to a 'badblocks' list.
This list is used by the various NVDIMM drivers to avoid consuming known
poison locations during IO.
The MCE handler gets called for both corrected and uncorrectable errors.
Until now, both kinds of errors have been added to the badblocks list.
However, corrected memory errors indicate that the problem has already
been fixed by hardware, and the resulting interrupt is merely a
notification to Linux.
As far as future accesses to that location are concerned, it is
perfectly fine to use, and thus doesn't need to be included in the above
badblocks list.
Add a check in the nfit MCE handler to filter out corrected mce events,
and only process uncorrectable errors.

[ Upstream commit 240714061c58e6b1abfb3322398a7634151c06cb ]
Bay and Cherry Trail DSTDs represent a different set of devices depending
on which OS the device think it is booting. One set of decices for Windows
and another set of devices for Android which targets the Android-x86 Linux
kernel fork (which e.g. used to have its own display driver instead of
using the i915 driver).
Which set of devices we are actually going to get is out of our control,
this is controlled by the ACPI OSID variable, which gets either set through
an EFI setup option, or sometimes is autodetected. So we need to support
both.
This commit adds support for the 80862286 and 808622C0 ACPI HIDs which we
get for the first resp. second DMA controller on Cherry Trail devices when
OSID is set to Android.

[ Upstream commit d0381bf4f80c571dde1244fe5b85dc35e8b3f546 ]
ACPI driver should make sure all the processor IDs in their ACPI Namespace
are unique. the driver performs a depth-first walk of the namespace tree
and calls the acpi_processor_ids_walk() to check the duplicate IDs.
But, the acpi_processor_ids_walk() mistakes the return value. If a
processor is checked, it returns true which causes the walk break
immediately, and other processors will never be checked.
Repace the value with AE_OK which is the standard acpi_status value.
And don't abort the namespace walk even on error.

[ Upstream commit 1cdda9486f5103fb133f88e662e48c504adbb779 ]
ACPI Low Power S0 Idle capabilities are announced via FADT table and can
be used to inform the kernel about the presence of one or more Low Power
Idle (LPI) entries as descried in LPIT table. LPIT table can exist
independently even if the FADT S0 Idle flag is not set and thus it could
confuse user since the following cpuidle attributes are created.
/sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us
/sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us
Presence or absence of above attributes could mean that the given
platform supports S0ix state or not.
This change allows to create the above cpuidle attributes only if
FADT table supports Low Power S0 Idle.

The type of a cache might not be specified by architectural mechanisms (ie
system registers), but its type might be specified in the PPTT. In this
case, we should populate the type of the cache, rather than leave it
undefined.
This fixes the issue where the cacheinfo driver will not populate sysfs
for such caches, resulting in the information missing from utilities like
lstopo and lscpu, thus degrading the user experience.

commit d3abaf43bab8d5b0a3c6b982100d9e2be96de4ad upstream.
The Address Range Scrub implementation tried to skip running scrubs
against ranges that were already scrubbed by the BIOS. Unfortunately
that support also resulted in early scrub completions as evidenced by
this debug output from nfit_test:
nd_region region9: ARS: range 1 short complete
nd_region region3: ARS: range 1 short complete
nd_region region4: ARS: range 2 ARS start (0)
nd_region region4: ARS: range 2 short complete
...i.e. completions without any indications that the scrub was started.
This state of affairs was hard to see in the code due to the
proliferation of state bits and mistakenly trying to track done state
per-range when the completion is a global property of the bus.
So, kill the four ARS state bits (ARS_REQ, ARS_REQ_REDO, ARS_DONE, and
ARS_SHORT), and replace them with just 2 request flags ARS_REQ_SHORT and
ARS_REQ_LONG. The implementation will still complete and reap the
results of BIOS initiated ARS, but it will not attempt to use that
information to affect the completion status of scrubbing the ranges from
a Linux perspective.
Instead, try to synchronously run a short ARS per range at init time and
schedule a long scrub in the background. If ARS is busy with an ARS
request, schedule both a short and a long scrub for when ARS returns to
idle. This logic also satisfies the intent of what ARS_REQ_REDO was
trying to achieve. The new rule is that the REQ flag stays set until the
next successful ars_start() for that range.
With the new policy that the REQ flags are not cleared until the next
start, the implementation no longer loses requests as can be seen from
the following log:
nd_region region3: ARS: range 1 ARS start short (0)
nd_region region9: ARS: range 1 ARS start short (0)
nd_region region3: ARS: range 1 complete
nd_region region4: ARS: range 2 ARS start short (0)
nd_region region9: ARS: range 1 complete
nd_region region9: ARS: range 1 ARS start long (0)
nd_region region4: ARS: range 2 complete
nd_region region3: ARS: range 1 ARS start long (0)
nd_region region9: ARS: range 1 complete
nd_region region3: ARS: range 1 complete
nd_region region4: ARS: range 2 ARS start long (0)
nd_region region4: ARS: range 2 complete
...note that the nfit_test emulated driver provides 2 buses, that is why
some of the range indices are duplicated. Notice that each range
now successfully completes a short and long scrub.

commit c64baa3a6fa207d112706bc5e7fd645cd8a8663f upstream.
AML opcodes come in two lengths: 1-byte opcodes and 2-byte, extended opcodes.
If an error occurs due to illegal opcodes during table load, the AML parser
needs to continue loading the table. In order to do this, it needs to skip
parsing of the offending opcode and operands associated with that opcode.
This change fixes the AML parse loop to correctly skip parsing of incorrect
extended opcodes. Previously, only the short opcodes were skipped correctly.

commit 4abb951b73ff0a8a979113ef185651aa3c8da19b upstream.
The table load process omitted adding the operation region address
range to the global list. This omission is problematic because the OS
queries the global list to check for address range conflicts before
deciding which drivers to load. This commit may result in warning
messages that look like the following:
[ 7.871761] ACPI Warning: system_IO range 0x00000428-0x0000042F conflicts with op_region 0x00000400-0x0000047F (\PMIO) (20180531/utaddress-213)
[ 7.871769] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
However, these messages do not signify regressions. It is a result of
properly adding address ranges within the global address list.

Commit 12864ff8545f (ACPI / LPSS: Avoid PM quirks on suspend and resume
from hibernation) bypasses lpss quirks for S3 and S4, by setting a flag
for S3/S4 in acpi_lpss_suspend(), and check that flag in
acpi_lpss_resume().
But this overlooks the boot case where acpi_lpss_resume() may get called
without a corresponding acpi_lpss_suspend() having been called.
Thus force setting the flag during boot.

Calling dmi_check_system() early only works on X86. Other
architectures initialize the DMI subsystem later so it's not
ready yet when ACPI itself gets initialized.
In the best case it results in a useless call to a function which
will do nothing. But depending on the dmi implementation, it could
also result in warnings. Best is to not call the function when it
can't work and isn't needed.
Additionally, if anyone ever needs to add non-x86 quirks, it would
surprisingly not work, so document the limitation to avoid confusion.

This is unnecessary and triggers a warning in the hypervisor.
Often systems have more processor entries in their ACPI tables than are
actually installed/active. The ACPI_STA_DEVICE_PRESENT bit cannot be
reliably used, but the ACPI_MADT_ENABLED bit can. In order to not
introduce new functions in the main ACPI processor driver code, simply
use acpi_get_phys_id(), which does more than we need, but which checks
the MADT enabled bit in the process. Any CPU for which we can't
determine the APIC ID is unlikely to work properly anyway, so the extra
checks done by acpi_get_phys_id() should do no harm.

Pull arm64 updates from Will Deacon:
"A bunch of good stuff in here. Worth noting is that we've pulled in
the x86/mm branch from -tip so that we can make use of the core
ioremap changes which allow us to put down huge mappings in the
vmalloc area without screwing up the TLB. Much of the positive
diffstat is because of the rseq selftest for arm64.
Summary:
- Wire up support for qspinlock, replacing our trusty ticket lock
code
- Add an IPI to flush_icache_range() to ensure that stale
instructions fetched into the pipeline are discarded along with the
I-cache lines
- Support for the GCC "stackleak" plugin
- Support for restartable sequences, plus an arm64 port for the
selftest
- Kexec/kdump support on systems booting with ACPI
- Rewrite of our syscall entry code in C, which allows us to zero the
GPRs on entry from userspace
- Support for chained PMU counters, allowing 64-bit event counters to
be constructed on current CPUs
- Ensure scheduler topology information is kept up-to-date with CPU
hotplug events
- Re-enable support for huge vmalloc/IO mappings now that the core
code has the correct hooks to use break-before-make sequences
- Miscellaneous, non-critical fixes and cleanups"

Commit fa85015c0d95 (ACPICA: Clear status of all events when entering
S5) made the sleep state entry code in ACPICA clear the status of all
ACPI events when entering S5 to fix a functional regression reported
against commit 18996f2db918 (ACPICA: Events: Stop unconditionally
clearing ACPI IRQs during suspend/resume). However, it is reported
now that the regression also affects system states other than S5 on
some systems and causes them to wake up from sleep prematurely.
For this reason, make the code in question clear the status of all
ACPI events when entering all sleep states (in addition to S5) to
avoid the premature wakeups (this may cause some wakeup events to
be missed in theory, but the likelihood of that is small and the
change here simply restores the previous behavior of the code).

Field elements listed in the init file used to be initialized after
the table load and before executing module-level code blocks. The
recent changes in module-level code mean that the table load becomes
a method execution. If fields are used within module-level code and
we are executing with -fi option, then these values are populated
after the table has finished loading. This commit changes the
initialization of objects listed in the init file so that field unit
values are populated during the table load.

Some devices have multiple I2cSerialBus resources and for things to work
an i2c-client must be instantiated for each, each with its own
i2c_device_id.
Normally we only instantiate an i2c-client for the first resource, using
the ACPI HID as id.
This commit adds a list of HIDs of devices, which need multiple i2c-clients
instantiated from a single fwnode, to acpi_device_enumeration_by_parent and
makes acpi_device_enumeration_by_parent return false for these devices so
that a platform device will be instantiated.
This allows the drivers/platform/x86/i2c-multi-instantiate.c driver, which
knows which i2c_device_id to use for each resource, to bind to the fwnode
and initiate an i2c-client for each resource.

Since commit 63347db0affa "ACPI / scan: Use acpi_bus_get_status() to
initialize ACPI_TYPE_DEVICE devs" the status field of normal acpi_devices
gets set to 0 by acpi_bus_type_and_status() and filled with its actual
value later when acpi_add_single_object() calls acpi_bus_get_status().
This means that any acpi_match_device_ids() calls in between will always
fail with -ENOENT.
We already have a workaround for this, which temporary forces status to
ACPI_STA_DEFAULT in drivers/acpi/x86/utils.c: acpi_device_always_present()
and the next commit in this series adds another acpi_match_device_ids()
call between status being initialized as 0 and the acpi_bus_get_status()
call.
Rather then adding another workaround, this commit makes
acpi_bus_type_and_status() initialize status to ACPI_STA_DEFAULT, this is
safe to do as the only code looking at status between the initialization
and the acpi_bus_get_status() call is those acpi_match_device_ids() calls.
Note this does mean that we need to (re)set status to 0 in case the
acpi_bus_get_status() call fails.

Commit 2c4d6baf1bc4 (ACPI / EC: Use ec_no_wakeup on more Thinkpad X1
Carbon 6th systems) changed the DMI table to match all systems where
DMI product family is "Thinkpad X1 Carbon 6th". However, the system I
have here has this string written differently (ThinkPad vs. Thinkpad)
which makes the match fail.
In addition to that, after BIOS upgrade Robin now has the same string
than my system has (perhaps newer BIOS has changed the string).
In any case add another DMI entry to acpi_ec_no_wakeup[] table hopefully
covering all the X1 Carbon 6th systems out there.

full_charge_capacity
On some devices (with a buggy _BIX implementation) full_charge_capacity
always reports as 0. This means that our energy_full sysfs attribute will
also always be 0, which is not useful to export.
Worse we calculate our reported capacity on full_charge_capacity and if it
is 0 we always report 0. This causes userspace to immediately shutdown or
hibernate the laptop since it assumes that the battery is critically low.
This commit makes us not report energy_full[_design] or capacity on such
broken devices, avoiding the immediate shutdown / hibernate from userspace.
