Mark Kconfig "comment" lines with "*** <commentstring> ***"
so that it is clear that these lines are comments and not some
kconfig item that cannot be modified.
This is helpful in some menus to be able to provide a menu
"sub-heading" for groups of similar config items.
This also makes the comments be presented in a way that is
similar to menuconfig and nconfig.

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 2217b98262 ("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.

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,

This patch adds the .offload_stats operation to synchronize hardware
stats with the expression data. Update the counter expression to use
this new interface. The hardware stats are retrieved from the netlink
dump path via FLOW_CLS_STATS command to the driver.

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.

On Qualcomm ARM32 platforms, the SMC call can return before it has
completed. If this occurs, the call can be restarted, but it requires
using the returned session ID value from the interrupted SMC call.
The ARM32 SMCC code already has the provision to add platform specific
quirks for things like this. So let's make use of it and add the
Qualcomm specific quirk (ARM_SMCCC_QUIRK_QCOM_A6) used by the QCOM_SCM
driver.
This change is similar to the below one added for ARM64 a while ago:
commit 82bcd08702 ("firmware: qcom: scm: Fix interrupted SCM calls")
Without this change, the Qualcomm ARM32 platforms like SDX55 will return
-EINVAL for SMC calls used for modem firmware loading and validation.

Since uprobes is not supported for thumb, check that the thumb bit is
not set when matching the uprobes instruction hooks.
The Arm UDF instructions used for uprobes triggering
(UPROBE_SWBP_ARM_INSN and UPROBE_SS_ARM_INSN) coincidentally share the
same encoding as a pair of unallocated 32-bit thumb instructions (not
UDF) when the condition code is 0b1111 (0xf). This in effect makes it
possible to trigger the uprobes functionality from thumb, and at that
using two unallocated instructions which are not permanently undefined.

Convert the ti,secure-proxy to yaml for better checks and documentation.
Differences being mostly in the examples:
- Dropped the example usage of mailbox client, it is better done in
tisci node definition.
- Switched reg usage for address-cells and size-cells 1 - aligned with
schema checks as well.
- included header in example for a buildable example.
While at this, lets make sure to support upto 100 rx threads even though
typically upto 1 threads is practically in use.
NOTE: The following checkpatch warning is generated since we do include the header
in the example, but this is a false positive warning.
WARNING: DT binding docs and includes should be a separate patch. See:

Starting with ISA v3.1, LPCR[AIL] no longer controls the interrupt
mode for HV=1 interrupts. Instead, a new LPCR[HAIL] bit is defined
which behaves like AIL=3 for HV interrupts when set.
Set HAIL on bare metal to give us mmu-on interrupts and improve
performance.
This also fixes an scv bug: we don't implement scv real mode (AIL=0)
vectors because they are at an inconvenient location, so we just
disable scv support when AIL can not be set. However powernv assumes
that LPCR[AIL] will enable AIL mode so it enables scv support despite
HV interrupts being AIL=0, which causes scv interrupts to go off into
the weeds.

After the fix from Jiri that disabled local IRQs instead of
just BHs (necessary to fix an issue with submitting a command
with IRQs already disabled), there was still a situation in
which we could deep in there enable BHs, if the device config
sets the apmg_wake_up_wa configuration, which is true on all
7000 series devices.
To fix that, but not require reverting commit 1ed08f6fb5
("iwlwifi: remove flags argument for nic_access"), split up
nic access into a version with BH manipulation to use most
of the time, and without it for this specific case where the
local IRQs are already disabled.
