Some bigger changes were done to this feature and we did not port this patch yet:
 * hack-5.4/207-disable-modorder.patch

This depends on BOOTMEM which was removed from the kernel, this needs some bigger changes:
 * hack-5.4/930-crashlog.patch

A different version of the FPU disable patch was merged upstream, OpenWrt needs some adaptations.
 * pending-5.4/304-mips_disable_fpu.patch

- no crashlog support yet as a required file got deleted upstream
- Removed patch below, which is now seen as a recursive dependency [1]
- Removed patch below due to build error [2]
- fix still required to avoid identical function def [3]
- Fixes included from Blocktrron
- Fixes included from Chunkeey
- Fix included from nbd regarding "dst leak in Flow Offload"

Subject: [PATCH] mtd: keep original flags for every struct mtd_info
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When allocating a new partition mtd subsystem runs internal tests in the
allocate_partition(). They may result in modifying specified flags (e.g.
dropping some /features/ like write access).
Those constraints don't have to be necessary true for subpartitions. It
may happen parent partition isn't block aligned (effectively disabling
write access) while subpartition may fit blocks nicely. In such case all
checks should be run again (starting with original flags value).

Subject: [PATCH] mtd: improve calculating partition boundaries when checking
for alignment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When checking for alignment mtd should check absolute offsets. It's
important for subpartitions as it doesn't make sense to check their
relative addresses.

Subject: [PATCH] bcma: keep a direct pointer to the struct device
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Accessing struct device is pretty useful/common so having a direct
pointer:
1) Simplifies some code
2) Makes bcma_bus_get_host_dev() unneeded
3) Allows further improvements like using dev_* printing helpers

Subject: [PATCH 1/1] Allow class-e address assignment in ifconfig and early
boot
While the linux kernel became mostly "class-e clean" a decade ago,
and most distributions long ago switched to the iproute2 suite
of utilities, which allow class-e (240.0.0.0/4) address assignment,
distributions relying on busybox, toybox and other forms of
ifconfig cannot assign class-e addresses without this kernel patch.
With this patch, also, a boot command line on these addresses is feasible:
(ip=248.0.1.2::248.0.1.1:255.255.255.0).
While CIDR has been obsolete for 2 decades, and a survey of all the
userspace open source code in the world shows most IN_whatever macros
are also obsolete... rather than obsolete CIDR from this ioctl entirely,
this patch merely enables class-e assignment, sanely.
H/T to Vince Fuller and his original patch here:

Subject: [PATCH 2/2] arm: cns3xxx: use actual size reads for PCIe
commit 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors")
reimplemented cns3xxx_pci_read_config() using pci_generic_config_read32(),
which preserved the property of only doing 32-bit reads.
It also replaced cns3xxx_pci_write_config() with pci_generic_config_write(),
so it changed writes from always being 32 bits to being the actual size,
which works just fine.
Due to:
- The documentation does not mention that only 32 bit access is allowed.
- Writes are already executed using the actual size
- Extensive testing shows that 8b, 16b and 32b reads work as intended
It makes perfectly sense to also swap 32 bit reading in favor of actual size.

Subject: [PATCH] arm64/sve: Disentangle <uapi/asm/ptrace.h> from
<uapi/asm/sigcontext.h>
Currently, <uapi/asm/sigcontext.h> provides common definitions for
describing SVE context structures that are also used by the ptrace
definitions in <uapi/asm/ptrace.h>.
For this reason, a #include of <asm/sigcontext.h> was added in
ptrace.h, but it this turns out that this can interact badly with
userspace code that tries to include ptrace.h on top of the libc
headers (which may provide their own shadow definitions for
sigcontext.h).
To make the headers easier for userspace to consume, this patch
bounces the common definitions into an __SVE_* namespace and moves
them to a backend header <uapi/asm/sve_context.h> that can be
included by the other headers as appropriate. This should allow
ptrace.h to be used alongside libc's sigcontext.h (if any) without
ill effects.
This should make the situation unambiguous: <asm/sigcontext.h> is
the header to include for the sigframe-specific definitions, while
<asm/ptrace.h> is the header to include for ptrace-specific
definitions.
To avoid conflicting with existing usage, <asm/sigcontext.h>
remains the canonical way to get the common definitions for
SVE_VQ_MIN, sve_vq_from_vl() etc., both in userspace and in the
kernel: relying on these being defined as a side effect of
including just <asm/ptrace.h> was never intended to be safe.

Subject: [PATCH] net: sched: Backport Introduce act_ctinfo action
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
ctinfo is a new tc filter action module. It is designed to restore
information contained in firewall conntrack marks to other packet fields
and is typically used on packet ingress paths. At present it has two
independent sub-functions or operating modes, DSCP restoration mode &
skb mark restoration mode.
The DSCP restore mode:
This mode copies DSCP values that have been placed in the firewall
conntrack mark back into the IPv4/v6 diffserv fields of relevant
packets.
The DSCP restoration is intended for use and has been found useful for
restoring ingress classifications based on egress classifications across
links that bleach or otherwise change DSCP, typically home ISP Internet
links. Restoring DSCP on ingress on the WAN link allows qdiscs such as
but by no means limited to CAKE to shape inbound packets according to
policies that are easier to set & mark on egress.
Ingress classification is traditionally a challenging task since
iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
lookups, hence are unable to see internal IPv4 addresses as used on the
typical home masquerading gateway. Thus marking the connection in some
manner on egress for later restoration of classification on ingress is
easier to implement.
Parameters related to DSCP restore mode:
dscpmask - a 32 bit mask of 6 contiguous bits and indicate bits of the
conntrack mark field contain the DSCP value to be restored.
statemask - a 32 bit mask of (usually) 1 bit length, outside the area
specified by dscpmask. This represents a conditional operation flag
whereby the DSCP is only restored if the flag is set. This is useful to
implement a 'one shot' iptables based classification where the
'complicated' iptables rules are only run once to classify the
connection on initial (egress) packet and subsequent packets are all
marked/restored with the same DSCP. A mask of zero disables the
conditional behaviour ie. the conntrack mark DSCP bits are always
restored to the ip diffserv field (assuming the conntrack entry is found
& the skb is an ipv4/ipv6 type)
e.g. dscpmask 0xfc000000 statemask 0x01000000
|----0xFC----conntrack mark----000000---|
| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0|
| DSCP | unused | flag |unused |
|-----------------------0x01---000000---|
| |
| |
---| Conditional flag
v only restore if set
|-ip diffserv-|
| 6 bits |
|-------------|
The skb mark restore mode (cpmark):
This mode copies the firewall conntrack mark to the skb's mark field.
It is completely the functional equivalent of the existing act_connmark
action with the additional feature of being able to apply a mask to the
restored value.
Parameters related to skb mark restore mode:
mask - a 32 bit mask applied to the firewall conntrack mark to mask out
bits unwanted for restoration. This can be useful where the conntrack
mark is being used for different purposes by different applications. If
not specified and by default the whole mark field is copied (i.e.
default mask of 0xffffffff)
e.g. mask 0x00ffffff to mask out the top 8 bits being used by the
aforementioned DSCP restore mode.
|----0x00----conntrack mark----ffffff---|
| Bits 31-24 | |
| DSCP & flag| some value here |
|---------------------------------------|
|
|
v
|------------skb mark-------------------|
| | |
| zeroed | |
|---------------------------------------|
Overall parameters:
zone - conntrack zone
control - action related control (reclassify | pipe | drop | continue |
ok | goto chain <CHAIN_INDEX>)

Subject: [PATCH 1/8] mtd: spinand: winbond: Add support for W25N01GV
W25N01GV is a single die version of the already supported
W25M02GV with half the capacity. Everything else is the
same so introduce support for W25N01GV.
Datasheet:http://www.winbond.com/resource-files/w25n01gv%20revl%20050918%20unsecured.pdf
Tested on 8devices Jalapeno dev board under OpenWrt running 4.19-rc5.

IMPORTANT NOTE
==============
The content of this patch has been adapted for Linux 4.19
Changes were made in Linux 5.x to add the bad-block limit
to the metadata available to the driver, adding a parameter
NAND_MEMORG(1, 2048, 128, 64, 1024, 20, 1, 1, 1),
^- New bad-block limit
This patch omits that parameter from the upstream patch
for compatibility with the Linux 4.19 driver.

Subject: [PATCH 3/3] mtd: spinand: Add support for GigaDevice GD5F1GQ4UFxxG
The GigaDevice GD5F1GQ4UFxxG SPI NAND is in current production devices
and, while it has the same logical layout as the E-series devices,
it differs in the SPI interfacing in significant ways.
This support is contingent on previous commits to:
* Add support for two-byte device IDs
* Define macros for page-read ops with three-byte addresses

Do not update the link interface mode while the link is down to avoid
spurious link interface changes.
Always call mac_config if we have a PHY to propagate the pause mode

While consolidating the PHY reset in phy_init_hw() an unconditionaly
BMCR soft-reset I became quite trigger happy with those. This was later
on deactivated for the Generic PHY driver on the premise that a prior
software entity (e.g: bootloader) might have applied workarounds in
commit 0878fff1f42c ("net: phy: Do not perform software reset for
Generic PHY").
Since we have a hook to wire-up a soft_reset callback, just use that and
get rid of the call to genphy_soft_reset() entirely. This speeds up
initialization and link establishment for most PHYs out there that do
not require a reset.
Fixes: 87aa9f9c61ad ("net: phy: consolidate PHY reset in phy_init_hw()")

Subject: [PATCH 603/660] net: phy: provide full set of accessor functions to
MMD registers
This adds full set of locked and unlocked accessor functions to read and
write PHY MMD registers and/or bitfields.
Set of functions exactly matches what is already available for PHY
legacy registers.

Subject: [PATCH 604/660] net: phy: add register modifying helpers returning 1
on change
When modifying registers there are scenarios where we need to know
whether the register content actually changed. This patch adds
new helpers to not break users of the current ones, phy_modify() etc.

Subject: [PATCH 612/660] net: sfp: Stop SFP polling and interrupt handling
during shutdown
SFP device polling can cause problems during the shutdown process if the
parent devices of the network controller have been shut down already.
This problem was seen on the iMX6 platform with PCIe devices, where
accessing the device after the bus is shut down causes a hang.
Free any acquired GPIO interrupts and stop all delayed work in the SFP
driver during the shutdown process, so that we ensure that no pending
operations are still occurring after the SFP shutdown completes.

Subject: [PATCH 613/660] net: phylink: don't start and stop SGMII PHYs in SFP
modules twice
SFP modules connected using the SGMII interface have their own PHYs which
are handled by the struct phylink's phydev field. On the other hand, for
the modules connected using 1000Base-X interface that field is not set.
Since commit ce0aa27ff3f6 ("sfp: add sfp-bus to bridge between network
devices and sfp cages") phylink_start() ends up setting the phydev field
using the sfp-bus infrastructure, which eventually calls phy_start() on it,
and then calling phy_start() again on the same phydev from phylink_start()
itself. Similar call sequence holds for phylink_stop(), only in the reverse
order. This results in WARNs during network interface bringup and shutdown
when a copper SFP module is connected, as phy_start() and phy_stop() are
called twice in a row for the same phy_device:

SFP modules with the 1000Base-X interface are not affected.
Place explicit calls to phy_start() and phy_stop() before enabling or after
disabling an attached SFP module, where phydev is not yet set (or is
already unset), so they will be made only from the inside of sfp-bus, if
needed.

From 1be8018db381200c24854e0c299206c557f76fe0 Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@armlinux.org.uk>
Date: Mon, 11 Nov 2019 11:58:09 +0000
Subject: [PATCH 638/660] net: phy: avoid matching all-ones clause 45 PHY IDs
We currently match clause 45 PHYs using any ID read from a MMD marked
as present in the "Devices in package" registers 5 and 6. However,
this is incorrect. 45.2 says:
"The definition of the term package is vendor specific and could be
a chip, module, or other similar entity."
so a package could be more or less than the whole PHY - a PHY could be
made up of several modules instantiated onto a single chip such as the
Marvell 88x3310, or some of the MMDs could be disabled according to
chip configuration, such as the Broadcom 84881.
In the case of Broadcom 84881, the "Devices in package" registers
contain 0xc000009b, meaning that there is a PHYXS present in the
package, but all registers in MMD 4 return 0xffff. This leads to our
matching code incorrectly binding this PHY to one of our generic PHY
drivers.
This patch changes the way we determine whether to attempt to match a
MMD identifier, or use it to request a module - if the identifier is
all-ones, then we skip over it. When reading the identifiers, we
initialise phydev->c45_ids.device_ids to all-ones, only reading the
device ID if the "Devices in package" registers indicates we should.
This avoids the generic drivers incorrectly matching on a PHY ID of
0xffffffff.

From 4c9633f75dc35abe1b9261e0415d77802f35741d Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@armlinux.org.uk>

Subject: [PATCH 639/660] net: phylink: fix link mode modification in PHY mode
Modifying the link settings via phylink_ethtool_ksettings_set() and
phylink_ethtool_set_pauseparam() didn't always work as intended for
PHY based setups, as calling phylink_mac_config() would result in the
unresolved configuration being committed to the MAC, rather than the
configuration with the speed and duplex setting.
This would work fine if the update caused the link to renegotiate,
but if no settings have changed, phylib won't trigger a renegotiation
cycle, and the MAC will be left incorrectly configured.
Avoid calling phylink_mac_config() unless we are using an inband mode
in phylink_ethtool_ksettings_set(), and use phy_set_asym_pause() as
introduced in 4.20 to set the PHY settings in
phylink_ethtool_set_pauseparam().

Subject: kernel: do not build modules.order
It is not needed for anything on the system and skipping this saves some
build time, especially in cases where there is nothing to do.
