Commit 03dbaa04a2e5 ("mmc: slot-gpio: Add support to enable irq wake on
cd_irq") enabled wakeup at initialization. However drivers may wish to
enable and disable based on different criteria. Add a helper function
mmc_gpio_set_cd_wake() to make it easy for drivers to do that.

Currently GRE sequence number can only be used in native
tunnel mode. This patch adds sequence number support for
gre collect metadata mode. RFC2890 defines GRE sequence
number to be specific to the traffic flow identified by the
key. However, this patch does not implement per-key seqno.
The sequence number is shared in the same tunnel device.
That is, different tunnel keys using the same collect_md
tunnel share single sequence number.

They're very hard to use properly as they do not consider the
GSO_BY_FRAGS case. Code should use skb_gso_validate_network_len
and skb_gso_validate_mac_len as they do consider this case.
Make the seglen functions static, which stops people using them
outside of skbuff.c

If you take a GSO skb, and split it into packets, will the network
length (L3 headers + L4 headers + payload) of those packets be small
enough to fit within a given MTU?
skb_gso_validate_mtu gives you the answer to that question. However,
we recently added to add a way to validate the MAC length of a split GSO
skb (L2+L3+L4+payload), and the names get confusing, so rename
skb_gso_validate_mtu to skb_gso_validate_network_len

Some operators prefer IPv6 path selection to use a standard 5-tuple
hash rather than just an L3 hash with the flow the label. To that end
add support to IPv6 for multipath hash policy similar to bf4e0a3db97eb
("net: ipv4: add support for ECMP hash policy choice"). The default
is still L3 which covers source and destination addresses along with
flow label and IPv6 protocol.

IPv6 does path selection for multipath routes deep in the lookup
functions. The next patch adds L4 hash option and needs the skb
for the forward path. To get the skb to the relevant FIB lookup
functions it needs to go through the fib rules layer, so add a
lookup_data argument to the fib_lookup_arg struct.

Do the following cleanups and simplifications:
- sched/sched.h already includes <asm/paravirt.h>, so no need to
include it in sched/core.c again.
- order the <linux/sched/*.h> headers alphabetically
- add all <linux/sched/*.h> headers to kernel/sched/sched.h
- remove all unnecessary includes from the .c files that
are already included in kernel/sched/sched.h.
Finally, make all scheduler .c files use a single common header:
#include "sched.h"
... which now contains a union of the relied upon headers.
This makes the various .c files easier to read and easier to handle.

Move duplicating and unflattening of an overlay flattened devicetree
(FDT) into the overlay application code. To accomplish this,
of_overlay_apply() is replaced by of_overlay_fdt_apply().
The copy of the FDT (aka "duplicate FDT") now belongs to devicetree
code, which is thus responsible for freeing the duplicate FDT. The
caller of of_overlay_fdt_apply() remains responsible for freeing the
original FDT.
The unflattened devicetree now belongs to devicetree code, which is
thus responsible for freeing the unflattened devicetree.
These ownership changes prevent early freeing of the duplicated FDT
or the unflattened devicetree, which could result in use after free
errors.
of_overlay_fdt_apply() is a private function for the anticipated
overlay loader.
Update unittest.c to use of_overlay_fdt_apply() instead of
of_overlay_apply().
Move overlay fragments from artificial locations in
drivers/of/unittest-data/tests-overlay.dtsi into one devicetree
source file per overlay. This led to changes in
drivers/of/unitest-data/Makefile and drivers/of/unitest.c.
- Add overlay directives to the overlay devicetree source files so
that dtc will compile them as true overlays into one FDT data
chunk per overlay.
- Set CFLAGS for drivers/of/unittest-data/testcases.dts so that
symbols will be generated for overlay resolution of overlays
that are no longer artificially contained in testcases.dts
- Unflatten and apply each unittest overlay FDT using
of_overlay_fdt_apply().
- Enable the of_resolve_phandles() check for whether the unflattened
overlay is detached. This check was previously disabled because the
overlays from tests-overlay.dtsi were not unflattened into detached
trees.
- Other changes to unittest.c infrastructure to manage multiple test
FDTs built into the kernel image (access by name instead of
arbitrary number).
- of_unittest_overlay_high_level(): previously unused code to add
properties from the overlay_base devicetree to the live tree
was triggered by the restructuring of tests-overlay.dtsi and thus
testcases.dts. This exposed two bugs: (1) the need to dup a
property before adding it, and (2) property 'name' is
auto-generated in the unflatten code and thus will be a duplicate
in the __symbols__ node - do not treat this duplicate as an error.

Pull libnvdimm fixes from Dan Williams:
"A 4.16 regression fix, three fixes for -stable, and a cleanup fix:
- During the merge window support for the new ACPI NVDIMM Platform
Capabilities structure disabled support for "deep flush", a
force-unit- access like mechanism for persistent memory. Restore
that mechanism.
- VFIO like RDMA is yet one more memory registration / pinning
interface that is incompatible with Filesystem-DAX. Disable long
term pins of Filesystem-DAX mappings via VFIO.
- The Filesystem-DAX detection to prevent long terms pins mistakenly
also disabled Device-DAX pins which are not subject to the same
block- map collision concerns.
- Similar to the setup path, softlockup warnings can trigger in the
shutdown path for large persistent memory namespaces. Teach
for_each_device_pfn() to perform cond_resched() in all cases.
- Boaz noticed that the might_sleep() in dax_direct_access() is stale
as of the v4.15 kernel.
These have received a build success notification from the 0day robot,
and the longterm pin fixes have appeared in -next. However, I recently
rebased the tree to remove some other fixes that need to be reworked
after review feedback.

SCTP GSO skbs have a gso_size of GSO_BY_FRAGS, so any sort of
unconditionally mangling of that will result in nonsense value
and would corrupt the skb later on.
Therefore, i) add two helpers skb_increase_gso_size() and
skb_decrease_gso_size() that would throw a one time warning and
bail out for such skbs and ii) refuse and return early with an
error in those BPF helpers that are affected. We do need to bail
out as early as possible from there before any changes on the
skb have been performed.

Commit 5905429ad856 ("fork: Provide usercopy whitelisting for
task_struct") noted that:
"While the blocked and saved_sigmask fields of task_struct are copied to
userspace (via sigmask_to_save() and setup_rt_frame()), it is always
copied with a static length (i.e. sizeof(sigset_t))."
However, this is not true in the case of compat signals, whose sigset
is copied by put_compat_sigset and receives size as an argument.
At most call sites, put_compat_sigset is copying a sigset from the
current task_struct. This triggers a warning when
CONFIG_HARDENED_USERCOPY is active. However, by marking this function as
static inline, the warning can be avoided because in all of these cases
the size is constant at compile time, which is allowed. The only site
where this is not the case is handling the rt_sigpending syscall, but
there the copy is being made from a stack local variable so does not
trigger the warning.
Move put_compat_sigset to compat.h, and mark it static inline. This
fixes the WARN on MIPS.

The "enable arbiter" bit is available only for pxa3xx based platforms
but it was experimentally shown that even if this bit is reserved,
some Marvell platforms (64-bit) actually need it to be set. The driver
always set this bit regardless of this property, which is harmless.
Then this property is not needed.
The "num_cs" field is always 1 and for a good reason, the old driver
(pxa3xx_nand.c) could only handle one. The new driver that replaces it
(marvell_nand.c) can handle more, but better use device tree for such
description. As there is only one available chip select, there is no
need for an array of partitions neither an array of partition numbers.

- there is a new GPIO bank called "DIF"
This means that Meson8b only has 83 actual GPIO lines. Without any holes
there would be 130 GPIO lines in total (120 are inherited from Meson8
plus 10 new from the DIF bank).
GPIOs greater GPIOZ_3 (whose ID is 83 - as a reminder: this is exactly
the number of actual GPIO lines on Meson8b and also the value of
meson8b_cbus_pinctrl_data.num_pins) cannot berequested. Using CARD_6
(which used ID 100 prior to this patch, "base of the GPIO controller was
382) as an example:
$ echo 482 > /sys/class/gpio/export
export_store: invalid GPIO 482
This removes all non-existing pins from to dt-bindings header file
(include/dt-bindings/gpio/meson8b-gpio.h). This allows us to have a
consecutive numbering for the GPIO #defines (GPIOY_2 doesn't exist for
example, so previously the GPIOY_3 ID was "GPIOY_1 + 2", after this
patch it is "GPIOY_1 + 1"). As a nice side-effect this means that we get
compile-time (instead of runtime) errors if Meson8b .dts uses a pin that
only exists on Meson8.
Additionally the pinctrl-meson8b driver has to be updated to handle this
new GPIO numbering. By default a struct meson_bank only handles GPIO
banks where the pins are numbered consecutively because it calculates
the bit offsets based on the GPIO IDs.
This is solved by taking the original BANK() definition and splitting it
into consecutive subsets (X0..11 and X16..21). The bit offsets for each
new bank includes the skipped GPIOs (the definition of the "X0..11" bank
is identical to the old "X" bank apart from the "last IRQ" field, the
definition of the new, split "X16..21" bank takes the original "X" bank
and adds 16 - the start of the new split bank - to the "first IRQ",
pullen bit, pull bit, dir bit, out bit and in bit).
Commit 984cffdeaeb7ea ("pinctrl: Fix gpio/pin mapping for Meson8b")
fixed the same issue by setting "ngpio" (of the gpio_chip) to 130.
Unfortunately this broke in db80f0e158e621 ("pinctrl: meson: get rid of
unneeded domain structures").
The solution from this patch was considered to be better than the
previous attempt at fixing this because it provides compile-time error
checking for the GPIOs that exist on Meson8 but don't exist on Meson8b.
The following pins were tested on an Odroid-C1 using the sysfs GPIO
interface checking that their value (high or low) could be read:
- GPIOX_0, GPIOX_1, GPIOX_2, GPIOX_3, GPIOX_4, GPIOX_5, GPIOX_6,
GPIOX_7, GPIOX_8, GPIOX_9, GPIOX_10, GPIOX_11, GPIOX_18, GPIOX_19,
GPIOX_20, GPIOX_21
- GPIOY_3, GPIOY_7, GPIOY_8
(some of these had to be pulled up because they were low by default,
others were high by default so these had to be pulled down)

This is second part of dealing with suboptimal device gso parameters.
In first patch (350c9f484bde "tcp_bbr: better deal with suboptimal GSO")
we dealt with devices having low gso_max_segs
Some devices lower gso_max_size from 64KB to 16 KB (r8152 is an example)
In order to probe an optimal cwnd, we want BBR being not sensitive
to whatever GSO constraint a device can have.
This patch removes tso_segs_goal() CC callback in favor of
min_tso_segs() for CC wanting to override sysctl_tcp_min_tso_segs
Next patch will remove bbr->tso_segs_goal since it does not have
to be persistent.

The various MFC entries are being held in the same kind of mr_tables
for both ipmr and ip6mr, and their traversal logic is identical.
Also, with the exception of the addresses [and other small tidbits]
the major bulk of the nla setting is identical.
Unite as much of the dumping as possible between the two.
Notice this requires creating an mr_table iterator for each, as the
for-each preprocessor macro can't be used by the common logic.

ipmr and ip6mr utilize the exact same methods for searching the
hashed resolved connections, difference being only in the construction
of the hash comparison key.
In order to unite the flow, introduce an mr_table operation set that
would contain the protocol specific information required for common
flows, in this case - the hash parameters and a comparison key
representing a (*,*) route.

mfc_cache and mfc6_cache are almost identical - the main difference is
in the origin/group addresses and comparison-key. Make a common
structure encapsulating most of the multicast routing logic - mr_mfc
and convert both ipmr and ip6mr into using it.
For easy conversion [casting, in this case] mr_mfc has to be the first
field inside every multicast routing abstraction utilizing it.
