Subject: [PATCH] mips: uasm: Add workaround for Loongson-2F nop CPU errata
This patch implements a workaround for the Loongson-2F nop in generated,
code, if the existing option CONFIG_CPU_NOP_WORKAROUND is set. Before,
the binutils option -mfix-loongson2f-nop was enabled, but no workaround
was done when emitting MIPS code. Now, the nop pseudo instruction is
emitted as "or ax,ax,zero" instead of the default "sll zero,zero,0". This
is consistent with the workaround implemented by binutils.

Subject: [PATCH] mips: bpf: Add JIT workarounds for CPU errata
This patch adds workarounds for the following CPU errata to the MIPS
eBPF JIT, if enabled in the kernel configuration.
- R10000 ll/sc weak ordering
- Loongson-3 ll/sc weak ordering
- Loongson-2F jump hang
The Loongson-2F nop errata is implemented in uasm, which the JIT uses,
so no additional mitigations are needed for that.

Subject: [PATCH] mips: bpf: Enable eBPF JITs
This patch enables the new eBPF JITs for 32-bit and 64-bit MIPS. It also
disables the old cBPF JIT to so cBPF programs are converted to use the
new JIT.
Workarounds for R4000 CPU errata are not implemented by the JIT, so the
JIT is disabled if any of those workarounds are configured.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
1. Use info from DT if available
It allows describing for example a fixed link. It's more accurate than
just guessing there may be one (depending on a chipset).
2. Verify PHY ID before trying to connect PHY
PHY addr 0x1e (30) is special in Broadcom routers and means a switch
connected as MDIO devices instead of a real PHY. Don't try connecting to
it.

Subject: [PATCH] net: bgmac: support MDIO described in DT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Check ethernet controller DT node for "mdio" subnode and use it with
of_mdiobus_register() when present. That allows specifying MDIO and its
PHY devices in a standard DT based way.
This is required for BCM53573 SoC support. That family is sometimes
called Northstar (by marketing?) but is quite different from it. It uses
different CPU(s) and many different hw blocks.
One of shared blocks in BCM53573 is Ethernet controller. Switch however
is not SRAB accessible (as it Northstar) but is MDIO attached.

Subject: [PATCH] net: dsa: b53: Drop BCM5301x workaround for a wrong CPU/IMP
port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On BCM5301x port 8 requires a fixed link when used.
Years ago when b53 was an OpenWrt downstream driver (with configuration
based on sometimes bugged NVRAM) there was a need for a fixup. In case
of forcing fixed link for (incorrectly specified) port 5 the code had to
actually setup port 8 link.
For upstream b53 driver with setup based on DT there is no need for that
workaround. In DT we have and require correct ports setup.

Subject: [PATCH] net: dsa: b53: Improve flow control setup on BCM5301x
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
According to the Broadcom's reference driver flow control needs to be
enabled for any CPU switch port (5, 7 or 8 - depending on which one is
used). Current code makes it work only for the port 5. Use
dsa_is_cpu_port() which solved that problem.

Subject: net: phy: at803x: fix resume for QCA8327 phy
From Documentation phy resume triggers phy reset and restart
auto-negotiation. Add a dedicated function to wait reset to finish as
it was notice a regression where port sometime are not reliable after a
suspend/resume session. The reset wait logic is copied from phy_poll_reset.
Add dedicated suspend function to use genphy_suspend only with QCA8337
phy and set only additional debug settings for QCA8327. With more test
it was reported that QCA8327 doesn't proprely support this mode and
using this cause the unreliability of the switch ports, especially the
malfunction of the port0.

Subject: net: phy: at803x: add DAC amplitude fix for 8327 phy
QCA8327 internal phy require DAC amplitude adjustement set to +6% with
100m speed. Also add additional define to report a change of the same
reg in QCA8337. (different scope it does set 1000m voltage)
Add link_change_notify function to set the proper amplitude adjustement
on PHY_RUNNING state and disable on any other state.

Subject: net: dsa: qca8k: add support for sgmii falling edge
Add support for this in the qca8k driver. Also add support for SGMII
rx/tx clock falling edge. This is only present for pad0, pad5 and
pad6 have these bit reserved from Documentation. Add a comment that this
is hardcoded to PAD0 as qca8327/28/34/37 have an unique sgmii line and
setting falling in port0 applies to both configuration with sgmii used
for port0 or port6.

Subject: net: dsa: qca8k: add support for cpu port 6
Currently CPU port is always hardcoded to port 0. This switch have 2 CPU
ports. The original intention of this driver seems to be use the
mac06_exchange bit to swap MAC0 with MAC6 in the strange configuration
where device have connected only the CPU port 6. To skip the
introduction of a new binding, rework the driver to address the
secondary CPU port as primary and drop any reference of hardcoded port.
With configuration of mac06 exchange, just skip the definition of port0
and define the CPU port as a secondary. The driver will autoconfigure
the switch to use that as the primary CPU port.

Subject: net: dsa: qca8k: rework rgmii delay logic and scan for cpu port 6
Future proof commit. This switch have 2 CPU ports and one valid
configuration is first CPU port set to sgmii and second CPU port set to
rgmii-id. The current implementation detects delay only for CPU port
zero set to rgmii and doesn't count any delay set in a secondary CPU
port. Drop the current delay scan function and move it to the sgmii
parser function to generalize and implicitly add support for secondary
CPU port set to rgmii-id. Introduce new logic where delay is enabled
also with internal delay binding declared and rgmii set as PHY mode.

Subject: net: dsa: qca8k: add support for pws config reg
Some qca8327 switch require to force the ignore of power on sel
strapping. Some switch require to set the led open drain mode in regs
instead of using strapping. While most of the device implements this
using the correct way using pin strapping, there are still some broken
device that require to be set using sw regs.
Introduce a new binding and support these special configuration.
As led open drain require to ignore pin strapping to work, the probe
fails with EINVAL error with incorrect configuration.

- "qca,qca8327": referenced as AR8327(N)-AL1A DR-QFN 148 pin package

-
-- #size-cells: must be 0
-- #address-cells: must be 1
-
-Optional properties:
-
-- reset-gpios: GPIO to be used to reset the whole device
-- qca,ignore-power-on-sel: Ignore power on pin strapping to configure led open
- drain or eeprom presence. This is needed for broken
- devices that have wrong configuration or when the oem
- decided to not use pin strapping and fallback to sw
- regs.
-- qca,led-open-drain: Set leds to open-drain mode. This requires the
- qca,ignore-power-on-sel to be set or the driver will fail
- to probe. This is needed if the oem doesn't use pin
- strapping to set this mode and prefers to set it using sw
- regs. The pin strapping related to led open drain mode is
- the pin B68 for QCA832x and B49 for QCA833x
-
-Subnodes:
-
-The integrated switch subnode should be specified according to the binding
-described in dsa/dsa.txt. If the QCA8K switch is connect to a SoC's external
-mdio-bus each subnode describing a port needs to have a valid phandle
-referencing the internal PHY it is connected to. This is because there's no
-N:N mapping of port and PHY id.
-To declare the internal mdio-bus configuration, declare a mdio node in the
-switch node and declare the phandle for the port referencing the internal
-PHY is connected to. In this config a internal mdio-bus is registered and
-the mdio MASTER is used as communication.
-
-Don't use mixed external and internal mdio-bus configurations, as this is
-not supported by the hardware.
-
-This switch support 2 CPU port. Normally and advised configuration is with
-CPU port set to port 0. It is also possible to set the CPU port to port 6
-if the device requires it. The driver will configure the switch to the defined
-port. With both CPU port declared the first CPU port is selected as primary
-and the secondary CPU ignored.
-
-A CPU port node has the following optional node:
-
-- fixed-link : Fixed-link subnode describing a link to a non-MDIO
- managed entity. See
- Documentation/devicetree/bindings/net/fixed-link.txt
- for details.
-- qca,sgmii-rxclk-falling-edge: Set the receive clock phase to falling edge.
- Mostly used in qca8327 with CPU port 0 set to
- sgmii.
-- qca,sgmii-txclk-falling-edge: Set the transmit clock phase to falling edge.
-- qca,sgmii-enable-pll : For SGMII CPU port, explicitly enable PLL, TX and RX
- chain along with Signal Detection.
- This should NOT be enabled for qca8327. If enabled with
- qca8327 the sgmii port won't correctly init and an err
- is printed.
- This can be required for qca8337 switch with revision 2.
- A warning is displayed when used with revision greater
- 2.
- With CPU port set to sgmii and qca8337 it is advised
- to set this unless a communication problem is observed.
-
-For QCA8K the 'fixed-link' sub-node supports only the following properties:
-
-- 'speed' (integer, mandatory), to indicate the link speed. Accepted
- values are 10, 100 and 1000
-- 'full-duplex' (boolean, optional), to indicate that full duplex is
- used. When absent, half duplex is assumed.

Subject: net: dsa: qca8k: fix delay applied to wrong cpu in parse_port_config
Fix delay settings applied to wrong cpu in parse_port_config. The delay
values is set to the wrong index as the cpu_port_index is incremented
too early. Start the cpu_port_index to -1 so the correct value is
applied to address also the case with invalid phy mode and not available
port.

Subject: net: dsa: qca8k: make sure PAD0 MAC06 exchange is disabled
Some device set MAC06 exchange in the bootloader. This cause some
problem as we don't support this strange mode and we just set the port6
as the primary CPU port. With MAC06 exchange, PAD0 reg configure port6
instead of port0. Add an extra check and explicitly disable MAC06 exchange
to correctly configure the port PAD config.

Subject: [PATCH] kconfig: solidify SATA_PMP config
SATA_PMP option in kernel config file disappears for every kernel_oldconfig refresh.
To prevent this, SATA_HOST is now selected automatically when SATA_PMP is enabled.
This patch can be dropped if SATA_MV is ever re-added into the config.

For blktrans devices with partitions (ie. part_bits != 0) the
assumption that the minor number of the mtdblock device matches
the mtdnum doesn't hold true.
Properly resolve mtd device from blktrans layer instead.

Miquel Raynal <miquel.raynal@bootlin.com>,
David Woodhouse <dwmw2@infradead.org>
Calling device_add_disk while holding mtd_table_mutex leads
to deadlock in case part_bits!=0 as block partition parsers
will try to open the newly created disks, trying to acquire
mutex once again.
Move device_add_disk to additional function called after
add partitions of an MTD device have been added and locks
have been released.

Subject: net: add packet mangeling
ar8216 switches have a hardware bug, which renders normal 802.1q support
unusable. Packet mangling is required to fix up the vlan for incoming
packets.

Subject: hack: arch: powerpc: drop register save/restore library from modules
Upstream GCC uses a libgcc function for saving/restoring registers. This
makes the code bigger, and upstream kernels need to carry that function
for every single kernel module. Our GCC is patched to avoid those
references, so we can drop the extra bloat for modules.

Subject: loop: Report EOPNOTSUPP properly
Properly plumb out EOPNOTSUPP from loop driver operations, which may
get returned when for instance a discard operation is attempted but not
supported by the underlying block device. Before this change, everything
was reported in the log as an I/O error, which is scary and not
helpful in debugging.

Subject: [PATCH] netfilter: connmark: introduce set-dscpmark
set-dscpmark is a method of storing the DSCP of an ip packet into
conntrack mark. In combination with a suitable tc filter action
(act_ctinfo) DSCP values are able to be stored in the mark on egress and
restored on ingress across links that otherwise alter or bleach DSCP.
This is useful for qdiscs such as CAKE which are able to shape according
to policies based on DSCP.
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.
x_tables CONNMARK set-dscpmark target solves the problem of storing the
DSCP to the conntrack mark in a way suitable for the new act_ctinfo tc
action to restore.
The set-dscpmark option accepts 2 parameters, a 32bit 'dscpmask' and a
32bit 'statemask'. The dscp mask must be 6 contiguous bits and
represents the area where the DSCP will be stored in the connmark. The
state mask is a minimum 1 bit length mask that must not overlap with the
dscpmask. It represents a flag which is set when the DSCP has been
stored in the conntrack mark. 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 state
mask of zero disables the setting of a status bit/s.
example syntax with a suitably modified iptables user space application:
iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --set-dscpmark 0xfc000000/0x01000000
Would store the DSCP in the top 6 bits of the 32bit mark field, and use
the LSB of the top byte as the 'DSCP has been stored' marker.

an identically configured tc action to restore looks like:
