Just like Ice Lake, Tiger Lake uses Cannon Lake's LTR information
and supports a few additional registers. Hence add the LTR registers
specific to Tiger Lake to the cnp_ltr_show_map[].
Also adjust the number of LTR IPs for Tiger Lake to the correct amount.

By default the Low Power Mode (LPM or sub-state) status registers will
latch condition status on every entry into Package C10. This is
configurable in the PMC to allow latching on any achievable sub-state. Add
a debugfs file to support this.
Also add the option to clear the status registers to 0. Clearing the status
registers before testing removes ambiguity around when the current values
were set.
The new file, latch_lpm_mode, looks like this:
[c10] S0i2.0 S0i3.0 S0i2.1 S0i3.1 S0i3.2 clear

Add the debugfs file, substate_requirements, to view the low power mode
(LPM) requirements for each enabled mode alongside the last latched status
of the condition.
After this patch, the new file will look like this:

Platforms that support low power modes (LPM) such as Tiger Lake maintain
requirements for each sub-state that a readable in the PMC. However, unlike
LPM status registers, requirement registers are not memory mapped but are
available from an ACPI _DSM. Collect the requirements for Tiger Lake using
the _DSM method and store in a buffer.

Modify the low power mode (LPM or sub-state) residency counters to display
in microseconds just like the slp_s0_residency counter. The granularity of
the counter is approximately 30.5us per tick. Double this value then divide
by two to maintain accuracy.

The current implementation of pmc_core_substate_res_show() is written
specifically for Tiger Lake. However, new platform will also have
sub-states and may support different modes. Therefore rewrite the code to
handle sub-states generically.
Obtain the number and type of enabled states form the PMC. Use the Low
Power Mode (LPM) priority register to store the states in order from
shallowest to deepest for displays. Add a for_each macro to simplify
this. While changing the sub-state display it makes sense to show only the
"enabled" sub-states instead of showing all possible ones. After this
patch, the debugfs file looks like this:
Substate Residency
S0i2.0 0
S0i3.0 0
S0i2.1 9329279
S0i3.1 0

The intel_pmc_core driver did not always bind to a device which meant it
lacked a struct device that could be used to maintain driver data. So a
global instance of struct pmc_dev was used for this purpose and functions
accessed this directly. Since the driver now binds to an ACPI device,
remove the global pmc_dev in favor of one that is allocated during probe.
Modify users of the global to obtain the object by argument instead.

The DMI callbacks, used for quirks, currently access the PMC by getting
the address a global pmc_dev struct. Instead, have the callbacks set a
global quirk specific variable. In probe, after calling dmi_check_system(),
pass pmc_dev to a function that will handle each quirk if its variable
condition is met. This allows removing the global pmc_dev later.

alignment in block mode
Since commit e085b51c74cc ("mmc: meson-gx: check for scatterlist size alignment in block mode"),
support for SDIO SD_IO_RW_EXTENDED transferts are properly filtered but some driver
like brcmfmac still gives a block sg buffer size not aligned with SDIO block,
triggerring a WARN_ONCE() with scary stacktrace even if the transfer works fine
but with possible degraded performances.
Simply replace with dev_warn_once() to inform user this should be fixed to avoid
degraded performance.
This should be ultimately fixed in brcmfmac, but since it's only a performance issue
the warning should be removed.

When mounting eCryptfs, a null "dev_name" argument to ecryptfs_mount()
causes a kernel panic if the parsed options are valid. The easiest way to
reproduce this is to call mount() from userspace with an existing
eCryptfs mount's options and a "source" argument of 0.
Error out if "dev_name" is null in ecryptfs_mount()

Commit 2217b9826246 ("binfmt_flat: revert "binfmt_flat: don't offset
the data start"") restored offsetting the start of the data section by
a number of words defined by MAX_SHARED_LIBS. As a result, since
MAX_SHARED_LIBS is never 0, a gap between the text and data sections
always exists. For architectures which cannot support a such gap
between the text and data sections (e.g. riscv nommu), flat binary
programs cannot be executed.
To allow an architecture to request no data start offset to allow for
contiguous text and data sections for binaries flagged with
FLAT_FLAG_RAM, introduce the new config option
CONFIG_BINFMT_FLAT_NO_DATA_START_OFFSET. Using this new option, the
macro DATA_START_OFFSET_WORDS is conditionally defined in binfmt_flat.c
to MAX_SHARED_LIBS for architectures tolerating or needing the data
start offset (CONFIG_BINFMT_FLAT_NO_DATA_START_OFFSET disabled case)
and to 0 when CONFIG_BINFMT_FLAT_NO_DATA_START_OFFSET is enabled.
DATA_START_OFFSET_WORDS is used in load_flat_file() to calculate the
data section length and start position.

Pull ARM SoC fixes from Arnd Bergmann:
"Another smaller set of fixes for three of the Arm platforms:
TI OMAP:
Fix swapped mmc device order also for omap3 that got changed with
the recent PROBE_PREFER_ASYNCHRONOUS changes. While eventually the
aliases should be board specific, all the mmc device instances are
all there in the SoC, and we do probe them by default so that PM
runtime can idle the devices if left enabled from the bootloader.
Qualcomm Snapdragon:
This bypasses the recently introduced interconnect handling in
the GENI (serial engine) driver when running off ACPI, as this
causes the GENI probe to fail and the Lenovo Yoga C630 to boot
without keyboard and touchpad.
Allwinner:
One 32kHz clock fix for the beelink gs1, a CD polarity fix for the
SoPine, some MAINTAINERS maintainance, and a clk / reset switch to
our headers"

Netfilter tries to reroute mangled packets as a different route might
need to be used following the mangling. When this happens, netfilter
does not populate the IP protocol, the source port and the destination
port in the flow key. Therefore, FIB rules that match on these fields
are ignored and packets can be misrouted.
Solve this by dissecting the outer flow and populating the flow key
before rerouting the packet. Note that flow dissection only happens when
FIB rules that match on these fields are installed, so in the common
case there should not be a penalty.

The nftables offload parser sets FLOW_DISSECTOR_KEY_BASIC .n_proto to the
ethertype field in the ethertype frame. However:
- FLOW_DISSECTOR_KEY_BASIC .n_proto field always stores either IPv4 or IPv6
ethertypes.
- FLOW_DISSECTOR_KEY_VLAN .vlan_tpid stores either the 802.1q and 802.1ad
ethertypes. Same as for FLOW_DISSECTOR_KEY_CVLAN.
This function adjusts the flow dissector to handle two scenarios:
1) FLOW_DISSECTOR_KEY_VLAN .vlan_tpid is set to 802.1q or 802.1ad.
Then, transfer:
- the .n_proto field to FLOW_DISSECTOR_KEY_VLAN .tpid.
- the original FLOW_DISSECTOR_KEY_VLAN .tpid to the
FLOW_DISSECTOR_KEY_CVLAN .tpid
- the original FLOW_DISSECTOR_KEY_CVLAN .tpid to the .n_proto field.
2) .n_proto is set to 802.1q or 802.1ad. Then, transfer:
- the .n_proto field to FLOW_DISSECTOR_KEY_VLAN .tpid.
- the original FLOW_DISSECTOR_KEY_VLAN .tpid to the .n_proto field.
