  The other fix is a revert-and-a-bit of a patch originally intended to
  allow PTE-level huge mappings for the VMAP area on 32-bit PPC 8xx. A
  side-effect of this change was that our pXd_set_huge() implementations
  could be replaced with generic dummy functions depending on the levels
  of page-table being used, which in turn broke the boot if we fail to
  create the linear mapping as a result of using these functions to
  operate on the pgd. Huge thanks to Michael Ellerman for modifying the
  revert so as not to regress PPC 8xx in terms of functionality.

  Anyway, that's the background and it's also available in the commit
  message along with Link tags pointing at all of the fun.

Any interraction with the buffer pool (seeding a buffer, acquire one) is
made through a software portal (SWP, a DPIO object).
There are circumstances where the dpaa2-switch driver probes on a DPSW
before any DPIO devices have been probed. In this case, seeding of the
buffer pool will lead to a panic since no SWPs are initialized.

To fix this, seed the buffer pool after making sure that the software
portals have been probed and are ready to be used.

====================
Fixes for KSZ DSA switch

These patches fix issues I encountered while using a KSZ9897 as a DSA
switch with a broadcom GENET network device as the DSA master device.

PATCH 1 fixes an invalid access to an SKB in case it is scattered.
PATCH 2 fixes incorrect hardware checksum calculation caused by the DSA
tag.

Changes in v2:
- instead of linearizing the SKBs only for KSZ switches ensure linearized
  SKBs for all tail taggers by clearing the feature flags NETIF_F_HW_SG and
  NETIF_F_FRAGLIST (suggested by Vladimir Oltean)

The patches have been tested with a KSZ9897 and apply against net-next.
====================

Signed-off-by: David S. Miller <davem@davemloft.net>

If the checksum calculation is offloaded to the network device (e.g due to
NETIF_F_HW_CSUM inherited from the DSA master device), the calculated
layer 4 checksum is incorrect. This is since the DSA tag which is placed
after the layer 4 data is considered as being part of the daa and thus
errorneously included into the checksum calculation.
To avoid this, always calculate the layer 4 checksum in software.

The function skb_put() that is used by tail taggers to make room for the
DSA tag must only be called for linearized SKBS. However in case that the
slave device inherited features like NETIF_F_HW_SG or NETIF_F_FRAGLIST the
SKB passed to the slaves transmit function may not be linearized.
Avoid those SKBs by clearing the NETIF_F_HW_SG and NETIF_F_FRAGLIST flags
for tail taggers.
Furthermore since the tagging protocol can be changed at runtime move the
code for setting up the slaves features into dsa_slave_setup_tagger().

This simple series of commands:

ip link add br0 type bridge vlan_filtering 1
ip link set swp0 master br0

fails on sja1105 with the following error:
[   33.439103] sja1105 spi0.1: vlan-lookup-table needs to have at least the default untagged VLAN
[   33.447710] sja1105 spi0.1: Invalid config, cannot upload
Warning: sja1105: Failed to change VLAN Ethertype.

For context, sja1105 has 3 operating modes:
- SJA1105_VLAN_UNAWARE: the dsa_8021q_vlans are committed to hardware
- SJA1105_VLAN_FILTERING_FULL: the bridge_vlans are committed to hardware
- SJA1105_VLAN_FILTERING_BEST_EFFORT: both the dsa_8021q_vlans and the
  bridge_vlans are committed to hardware

Swapping out a VLAN list and another in happens in
sja1105_build_vlan_table(), which performs a delta update procedure.
That function is called from a few places, notably from
sja1105_vlan_filtering() which is called from the
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING handler.

The above set of 2 commands fails when run on a kernel pre-commit
8841f6e6 ("net: dsa: sja1105: make devlink property
best_effort_vlan_filtering true by default"). So the priv->vlan_state
transition that takes place is between VLAN-unaware and full VLAN
filtering. So the dsa_8021q_vlans are swapped out and the bridge_vlans
are swapped in.

So why does it fail?

Well, the bridge driver, through nbp_vlan_init(), first sets up the
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING attribute, and only then
proceeds to call nbp_vlan_add for the default_pvid.

So when we swap out the dsa_8021q_vlans and swap in the bridge_vlans in
the SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING handler, there are no bridge
VLANs (yet). So we have wiped the VLAN table clean, and the low-level
static config checker complains of an invalid configuration. We _will_
add the bridge VLANs using the dynamic config interface, albeit later,
when nbp_vlan_add() calls us. So it is natural that it fails.

So why did it ever work?

Surprisingly, it looks like I only tested this configuration with 2
things set up in a particular way:
- a network manager that brings all ports up
- a kernel with CONFIG_VLAN_8021Q=y

It is widely known that commit ad1afb00 ("vlan_dev: VLAN 0 should be
treated as "no vlan tag" (802.1p packet)") installs VID 0 to every net
device that comes up. DSA treats these VLANs as bridge VLANs, and
therefore, in my testing, the list of bridge_vlans was never empty.

However, if CONFIG_VLAN_8021Q is not enabled, or the port is not up when
it joins a VLAN-aware bridge, the bridge_vlans list will be temporarily
empty, and the sja1105_static_config_reload() call from
sja1105_vlan_filtering() will fail.

To fix this, the simplest thing is to keep VID 4095, the one used for
CPU-injected control packets since commit ed040abc ("net: dsa:
sja1105: use 4095 as the private VLAN for untagged traffic"), in the
list of bridge VLANs too, not just the list of tag_8021q VLANs. This
ensures that the list of bridge VLANs will never be empty.

Currently, in sctp_packet_config(), sctp_transport_pmtu_check() is
called to update transport pathmtu with dst's mtu when dst's mtu
has been changed by non sctp stack like xfrm.

However, this should only happen when SPP_PMTUD_ENABLE is set, no
matter where dst's mtu changed. This patch is to fix by checking
SPP_PMTUD_ENABLE flag before calling sctp_transport_pmtu_check().

- Change ASSR enabling code while preserving original code flow
  as much as possible
- Simplify the code on guarding with internal display flag

[Why]
PMFW message which previously thought to only control Z9 controls both
Z9 and Z10. Also HW design team requested that Z9 must only be supported
on eDP due to content protection interop.

[How]
Change zstate support condition to match updated policy

[Why]
Populate dtbclk values from bwparams for dcn302, dcn303.

[How]
dtbclk values are fetched from bandwidthparams for all DPM levels and
for DPM levels where smu returns 0, previous level values are reported.

DCN 3x increased Line buffer size for DCHUB latency hiding, from 4 lines
of 4K resolution lines to 5 lines of 4K resolution lines. All Line
Buffer can be used as extended memory for P State change latency hiding.
The maximum number of lines is increased to 32 lines. Finally,
LB_MEMORY_CONFIG_1 (LB memory piece 1) and LB_MEMORY _CONFIG_2 (LB
memory piece 2) are not affected, no change in size, only 3 pieces is
affected, i.e., when all 3 pieces are used in both LB_MEMORY_CONFIG_0
and LB_MEMORY_CONFIG_3 (for 4:2:0) modes.

[why]
DCN31 doesn't have MALL in DMUB so to avoid sending unknown commands to
DMUB just remove the function pointer.

[how]
Remove apply_idle_power_optimizations from function pointers structure
for DCN31

[Why]
We used to unconditionally set backlight path as AUX for panels capable
of backlight adjustment via DPCD in set default brightness.

[How]
This should be limited to OLED panel only since we control backlight via
PWM path for SDR mode in LCD HDR panel.

[Why & How]
We're missing a default value for dram_channel_width_bytes in the
DCN3.1 SOC bounding box and we don't currently have the interface in
place to query the actual value from VBIOS.

Put in a hardcoded default until we have the interface in place.

[Why]
Hardcoding the VCO frequency isn't correct since we don't own or control
the value.

In the case where the hardcode is also missing we can't lightup display.

[How]
Query from the CLK register instead. Update the DFS frequency to be able
to compute the VCO frequency.
