This reverts commit 32cf1a12cad43358e47dac8014379c2f33dfbed4.
The 'exisitng buffer' in this case is the firmware provided table, and
we should not modify that in place. This fixes a crash on arm64 with
initrd table overrides, in which case the DSDT is not mapped with
read/write permissions.

If the maximum performance level taken for computing the
arch_max_freq_ratio value used in the x86 scale-invariance code is
higher than the one corresponding to the cpuinfo.max_freq value
coming from the acpi_cpufreq driver, the scale-invariant utilization
falls below 100% even if the CPU runs at cpuinfo.max_freq or slightly
faster, which causes the schedutil governor to select a frequency
below cpuinfo.max_freq. That frequency corresponds to a frequency
table entry below the maximum performance level necessary to get to
the "boost" range of CPU frequencies which prevents "boost"
frequencies from being used in some workloads.
While this issue is related to scale-invariance, it may be amplified
by commit db865272d9c4 ("cpufreq: Avoid configuring old governors as
default with intel_pstate") from the 5.10 development cycle which
made it extremely easy to default to schedutil even if the preferred
driver is acpi_cpufreq as long as intel_pstate is built too, because
the mere presence of the latter effectively removes the ondemand
governor from the defaults. Distro kernels are likely to include
both intel_pstate and acpi_cpufreq on x86, so their users who cannot
use intel_pstate or choose to use acpi_cpufreq may easily be
affectecd by this issue.
If CPPC is available, it can be used to address this issue by
extending the frequency tables created by acpi_cpufreq to cover the
entire available frequency range (including "boost" frequencies) for
each CPU, but if CPPC is not there, acpi_cpufreq has no idea what
the maximum "boost" frequency is and the frequency tables created by
it cannot be extended in a meaningful way, so in that case make it
ask the arch scale-invariance code to to use the "nominal" performance
level for CPU utilization scaling in order to avoid the issue at hand.

A severe performance regression on AMD EPYC processors when using
the schedutil scaling governor was discovered by Phoronix.com and
attributed to the following commits:
41ea667227ba ("x86, sched: Calculate frequency invariance for AMD
systems")
976df7e5730e ("x86, sched: Use midpoint of max_boost and max_P for
frequency invariance on AMD EPYC")
The source of the problem is that the maximum performance level taken
for computing the arch_max_freq_ratio value used in the x86 scale-
invariance code is higher than the one corresponding to the
cpuinfo.max_freq value coming from the acpi_cpufreq driver.
This effectively causes the scale-invariant utilization to fall below
100% even if the CPU runs at cpuinfo.max_freq or slightly faster, so
the schedutil governor selects a frequency below cpuinfo.max_freq
then. That frequency corresponds to a frequency table entry below
the maximum performance level necessary to get to the "boost" range
of CPU frequencies.
However, if the cpuinfo.max_freq value coming from acpi_cpufreq was
higher, the schedutil governor would select higher frequencies which
in turn would allow acpi_cpufreq to set more adequate performance
levels and to get to the "boost" range of CPU frequencies more often.
This issue affects any systems where acpi_cpufreq is used and the
"boost" (or "turbo") frequencies are enabled, not just AMD EPYC.
Moreover, commit db865272d9c4 ("cpufreq: Avoid configuring old
governors as default with intel_pstate") from the 5.10 development
cycle made it extremely easy to default to schedutil even if the
preferred driver is acpi_cpufreq as long as intel_pstate is built
too, because the mere presence of the latter effectively removes the
ondemand governor from the defaults. Distro kernels are likely to
include both intel_pstate and acpi_cpufreq on x86, so their users
who cannot use intel_pstate or choose to use acpi_cpufreq may
easily be affectecd by this issue.
To address this issue, extend the frequency table constructed by
acpi_cpufreq for each CPU to cover the entire range of available
frequencies (including the "boost" ones) if CPPC is available and
indicates that "boost" (or "turbo") frequencies are enabled. That
causes cpuinfo.max_freq to become the maximum "boost" frequency of
the given CPU (instead of the maximum frequency returned by the ACPI
_PSS object that corresponds to the "nominal" performance level).

This reverts commit 842067940a3e3fc008a60fee388e000219b32632.
For some solutions e.g. sound/soc/intel/catpt, DW DMA is part of a
compound device (in that very example, domains: ADSP, SSP0, SSP1, DMA0
and DMA1 are part of a single entity) rather than being a standalone
one. Driver for said device may enlist DMA to transfer data during
suspend or resume sequences.
Manipulating RPM explicitly in dw's DMA request and release channel
functions causes suspend() to also invoke resume() for the exact same
device. Similar situation occurs for resume() sequence. Effectively
renders device dysfunctional after first suspend() attempt. Revert the
change to address the problem.

The Voyo winpad A15 tablet contains quite generic names in the sys_vendor

rcmfmac4330-sdio.To be filled by O.E.M.-To be filled by O.E.M..txt
as nvram file which is a bit too generic.
Add a DMI quirk so that a unique and clearly identifiable nvram file name
is used on the Voyo winpad A15 tablet.
While preparing a matching linux-firmware update I noticed that the nvram
is identical to the nvram used on the Prowise-PT301 tablet, so the new DMI
quirk entry simply points to the already existing Prowise-PT301 nvram file.

In commit d3ccc14dfe95 most of the tasklets in this driver was
updated to the new API. However for the rx_work_tasklet only the
type of the callback was changed from
void _rtl_rx_work(unsigned long data)
to
void _rtl_rx_work(struct tasklet_struct *t).
The initialization of rx_work_tasklet was still open-coded and the
function pointer just cast into the old type, and hence nothing sets
rx_work_tasklet.use_callback = true and the callback was still called as
t->func(t->data);
with uninitialized/zero t->data.
Commit 6b8c7574a5f8 changed the casting of _rtl_rx_work a bit and
initialized t->data to a pointer to the tasklet cast to an unsigned
long.
This way calling t->func(t->data) might actually work through all the
casting, but it still doesn't update the code to use the new tasklet
API.
Let's use the new tasklet_setup to initialize rx_work_tasklet properly
and set rx_work_tasklet.use_callback = true so that the callback is
called as
t->callback(t);
without all the casting.

This patch prepares for qmi_wwan driver support for the device.
Previously "option" driver mapped itself to interfaces 0 and 3 (matching
ff/ff/ff), while interface 3 is in fact a QMI port.
Interfaces 1 and 2 (matching ff/00/00) expose AT commands,
and weren't supported previously at all.
Without this patch, a possible conflict would exist if device ID was
added to qmi_wwan driver for interface 3.
Update and simplify device ID to match interfaces 0-2 directly,
to expose QCDM (0), PCUI (1), and modem (2) ports and avoid conflict
with QMI (3), and ADB (4).
The modem is used inside ZTE MF283+ router and carriers identify it as
such.
Interface mapping is:

Pull libnvdimm fixes from Dan Williams:
"A fix for a crash scenario that has been present since the initial
merge, a minor regression in sysfs attribute visibility, and a fix for
some flexible array warnings.
The bulk of this pull is an update to the libnvdimm unit test
infrastructure to test non-ACPI platforms. Given there is zero
regression risk for test updates, and the tests enable validation of
bits headed towards the next merge window, I saw no reason to hold the
new tests back. Santosh originally submitted this before the v5.11
window opened.
Summary:
- Fix a crash when sysfs accesses race 'dimm' driver probe/remove.
- Fix a regression in 'resource' attribute visibility necessary for
mapping badblocks and other physical address interrogations.
- Fix some flexible array warnings
- Expand the unit test infrastructure for non-ACPI platforms"

- Add extra serialization to non-serializing MSRs (IA32_TSC_DEADLINE

theoretical issues.
- Re-add the EPB MSR reading on turbostat so that it works on older
kernels which don't have the corresponding EPB sysfs file.
- Add Alder Lake to the list of CPUs which support split lock.
- Fix %dr6 register handling in order to be able to set watchpoints
with gdb again.

The global gpio_desc pointer and int vbus_irq were defined in the header,
instead put the definitions in the translation unit and make them static as
there's only a single consumer, and these symbols shouldn't pollute the
global namespace.
This fixes the following sparse warnings for this driver:
drivers/staging/emxx_udc/emxx_udc.c: note: in included file:
drivers/staging/emxx_udc/emxx_udc.h:23:18: warning: symbol 'vbus_gpio' was not
declared. Should it be static? drivers/staging/emxx_udc/emxx_udc.h:24:5:

====================
100GbE Intel Wired LAN Driver Updates 2021-02-05
This series contains updates to ice driver only.
Jake adds adds reporting of timeout length during devlink flash and
implements support to report devlink info regarding the version of
firmware that is stored (downloaded) to the device, but is not yet active.
ice_devlink_info_get will report "stored" versions when there is no
pending flash update. Version info includes the UNDI Option ROM, the
Netlist module, and the fw.bundle_id.
Gustavo A. R. Silva replaces a one-element array to flexible-array
member.
Bruce utilizes flex_array_size() helper and removes dead code on a check
for a condition that can't occur.
v2:
* removed security revision implementation, and re-ordered patches to
account for this removal
* squashed patches implementing ice_read_flash_module to avoid patches
refactoring the implementation of a previous patch in the series
* modify ice_devlink_info_get to always report "stored" versions instead
of only reporting them when a pending flash update is ready.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
ice: remove dead code
ice: use flex_array_size where possible
ice: Replace one-element array with flexible-array member
ice: display stored UNDI firmware version via devlink info
ice: display stored netlist versions via devlink info
ice: display some stored NVM versions via devlink info
ice: introduce function for reading from flash modules
ice: cache NVM module bank information
ice: introduce context struct for info report
ice: create flash_info structure and separate NVM version
ice: report timeout length for erasing during devlink flash
