Add bindings for the MT7981 pinctrl driver. As MT7981 has most features
in common with MT7986 (but has a different layout in terms on pinctrl
and clocks), the existing mediatek,mt7986-pinctrl.yaml was used as an
example to create a similar document covering MT7981.

The ISO 11783-5 standard, in "4.5.2 - Address claim requirements", states:
d) No CF shall begin, or resume, transmission on the network until 250
ms after it has successfully claimed an address except when
responding to a request for address-claimed.
But "Figure 6" and "Figure 7" in "4.5.4.2 - Address-claim
prioritization" show that the CF begins the transmission after 250 ms
from the first AC (address-claimed) message even if it sends another AC
message during that time window to resolve the address contention with
another CF.
As stated in "4.4.2.3 - Address-claimed message":
In order to successfully claim an address, the CF sending an address
claimed message shall not receive a contending claim from another CF
for at least 250 ms.
As stated in "4.4.3.2 - NAME management (NM) message":
1) A commanding CF can
d) request that a CF with a specified NAME transmit the address-
claimed message with its current NAME.
2) A target CF shall
d) send an address-claimed message in response to a request for a
matching NAME
Taking the above arguments into account, the 250 ms wait is requested
only during network initialization.
Do not restart the timer on AC message if both the NAME and the address
match and so if the address has already been claimed (timer has expired)
or the AC message has been sent to resolve the contention with another
CF (timer is still running).

This patch adds a flag, FAN_INFO and an extensible buffer to provide
additional information about response decisions. The buffer contains
one or more headers defining the information type and the length of the
following information. The patch defines one additional information
type, FAN_RESPONSE_INFO_AUDIT_RULE, to audit a rule number. This will
allow for the creation of other information types in the future if other
users of the API identify different needs.
The kernel can be tested if it supports a given info type by supplying
the complete info extension but setting fd to FAN_NOFD. It will return
the expected size but not issue an audit record.

We have two IS1 filters of the OCELOT_VCAP_KEY_ANY key type (the one with
"action vlan pop" and the one with "action vlan modify") and one of the
OCELOT_VCAP_KEY_IPV4 key type (the one with "action skbedit priority").
But we have no IS1 filter with the OCELOT_VCAP_KEY_ETYPE key type, and
there was an uncaught breakage there.
To increase test coverage, convert one of the OCELOT_VCAP_KEY_ANY
filters to OCELOT_VCAP_KEY_ETYPE, by making the filter also match on the
MAC SA of the traffic sent by mausezahn, $h1_mac.

Alternative short title: don't instruct the hardware to match on
EtherType with "protocol 802.1Q" flower filters. It doesn't work for the
reasons detailed below.
With a command such as the following:
tc filter add dev $swp1 ingress chain $(IS1 2) pref 3 \
protocol 802.1Q flower skip_sw vlan_id 200 src_mac $h1_mac \
action vlan modify id 300 \
action goto chain $(IS2 0 0)
the created filter is set by ocelot_flower_parse_key() to be of type
OCELOT_VCAP_KEY_ETYPE, and etype is set to {value=0x8100, mask=0xffff}.
This gets propagated all the way to is1_entry_set() which commits it to
hardware (the VCAP_IS1_HK_ETYPE field of the key). Compare this to the
case where src_mac isn't specified - the key type is OCELOT_VCAP_KEY_ANY,
and is1_entry_set() doesn't populate VCAP_IS1_HK_ETYPE.
The problem is that for VLAN-tagged frames, the hardware interprets the
ETYPE field as holding the encapsulated VLAN protocol. So the above
filter will only match those packets which have an encapsulated protocol
of 0x8100, rather than all packets with VLAN ID 200 and the given src_mac.
The reason why this is allowed to occur is because, although we have a
block of code in ocelot_flower_parse_key() which sets "match_protocol"
to false when VLAN keys are present, that code executes too late.
There is another block of code, which executes for Ethernet addresses,
and has a "goto finished_key_parsing" and skips the VLAN header parsing.
By skipping it, "match_protocol" remains with the value it was
initialized with, i.e. "true", and "proto" is set to f->common.protocol,
or 0x8100.
The concept of ignoring some keys rather than erroring out when they are
present but can't be offloaded is dubious in itself, but is present
since the initial commit fe3490e610 ("net: mscc: ocelot: Hardware
ofload for tc flower filter"), and it's outside of the scope of this
patch to change that.
The problem was introduced when the driver started to interpret the
flower filter's protocol, and populate the VCAP filter's ETYPE field
based on it.
To fix this, it is sufficient to move the code that parses the VLAN keys
earlier than the "goto finished_key_parsing" instruction. This will
ensure that if we have a flower filter with both VLAN and Ethernet
address keys, it won't match on ETYPE 0x8100, because the VLAN key
parsing sets "match_protocol = false".

This reverts commit 115d9d77bb.
The pages being freed by memblock_free_late() have already been
initialized, but if they are in the deferred init range,
__free_one_page() might access nearby uninitialized pages when trying to
coalesce buddies. This can, for example, trigger this BUG:

Frank reports that in a mt7530 setup where some ports are standalone and
some are in a VLAN-aware bridge, 8021q uppers of the standalone ports
lose their VLAN tag on xmit, as seen by the link partner.
This seems to occur because once the other ports join the VLAN-aware
bridge, mt7530_port_vlan_filtering() also calls
mt7530_port_set_vlan_aware(ds, cpu_dp->index), and this affects the way
that the switch processes the traffic of the standalone port.
Relevant is the PVC_EG_TAG bit. The MT7530 documentation says about it:
EG_TAG: Incoming Port Egress Tag VLAN Attribution
0: disabled (system default)
1: consistent (keep the original ingress tag attribute)
My interpretation is that this setting applies on the ingress port, and
"disabled" is basically the normal behavior, where the egress tag format
of the packet (tagged or untagged) is decided by the VLAN table
(MT7530_VLAN_EGRESS_UNTAG or MT7530_VLAN_EGRESS_TAG).
But there is also an option of overriding the system default behavior,
and for the egress tagging format of packets to be decided not by the
VLAN table, but simply by copying the ingress tag format (if ingress was
tagged, egress is tagged; if ingress was untagged, egress is untagged;
aka "consistent). This is useful in 2 scenarios:
- VLAN-unaware bridge ports will always encounter a miss in the VLAN
table. They should forward a packet as-is, though. So we use
"consistent" there. See commit e045124e93 ("net: dsa: mt7530: fix
tagged frames pass-through in VLAN-unaware mode").
- Traffic injected from the CPU port. The operating system is in god
mode; if it wants a packet to exit as VLAN-tagged, it sends it as
VLAN-tagged. Otherwise it sends it as VLAN-untagged*.
*This is true only if we don't consider the bridge TX forwarding offload
feature, which mt7530 doesn't support.
So for now, make the CPU port always stay in "consistent" mode to allow
software VLANs to be forwarded to their egress ports with the VLAN tag
intact, and not stripped.

The "pci-OF-bus-map" property was declared deprecated in 2006 [1] and to
the best of everyone's knowledge is not used by anything anymore [2].
The creation of the property was disabled on powermac (arch/powerpc) in
2005 by commit 35499c0195 ("powerpc: Merge in 64-bit powermac
support."). But it is still created by default on CHRP.
On powermac the actual map (pci_to_OF_bus_map) is still used by default,
even though the device tree property is not created.
Add an option to enable/disable use of the pci_to_OF_bus_map, and
creation of the property (on CHRP).
Disabling the option allows enabling CONFIG_PPC_PCI_BUS_NUM_DOMAIN_DEPENDENT
which allows "normal" bus numbering and more than 256 buses, like 64-bit
and other architectures.
Mark the new option as default n, the intention is that the option and
the code will be removed in a future release.

We reference dump buffers both by their handle as well as their
object. The problem is now that when anybody iterates over the DRM
framebuffers and exports the underlying GEM objects through DMA-buf
we run into a circular reference count situation.
The result is that the fbdev handling holds the GEM handle preventing
the DMA-buf in the GEM object to be released. This DMA-buf in turn
holds a reference to the driver module which on unload would release
the fbdev.
Break that loop by releasing the handle as soon as the DRM
framebuffer object is created. The DRM framebuffer and the DRM client
buffer structure still hold a reference to the underlying GEM object
preventing its destruction.
