The current logic only works if the PIO is between two
other ND user options. This fixes it so that the PIO
can also be either before or after other ND user options
(for example the first or last option in the RA).
side note: there's actually Android tests verifying
a portion of the old broken behaviour, so:
https://android-review.googlesource.com/c/kernel/tests/+/3196704
fixes those up.

Following the implementation of "igc: Add TransmissionOverrun counter"
patch, when a taprio command is triggered by user, igc processes two
commands: TAPRIO_CMD_REPLACE followed by TAPRIO_CMD_STATS. However, both
commands unconditionally pass through igc_tsn_offload_apply() which
evaluates and triggers reset adapter. The double reset causes issues in
the calculation of adapter->qbv_count in igc.
TAPRIO_CMD_REPLACE command is expected to reset the adapter since it
activates qbv. It's unexpected for TAPRIO_CMD_STATS to do the same
because it doesn't configure any driver-specific TSN settings. So, the
evaluation in igc_tsn_offload_apply() isn't needed for TAPRIO_CMD_STATS.
To address this, commands parsing are relocated to
igc_tsn_enable_qbv_scheduling(). Commands that don't require an adapter
reset will exit after processing, thus avoiding igc_tsn_offload_apply().

The carrier_lock spinlock protects the carrier detection. While it is
held, framer_get_status() is called which in turn takes a mutex.
This is not correct and can lead to a deadlock.

The cited commit allocates a new modify header to replace the old
one when updating CT entry. But if failed to allocate a new one, eg.
exceed the max number firmware can support, modify header will be
an error pointer that will trigger a panic when deallocating it. And
the old modify header point is copied to old attr. When the old
attr is freed, the old modify header is lost.
Fix it by restoring the old attr to attr when failed to allocate a
new modify header context. So when the CT entry is freed, the right
modify header context will be freed. And the panic of accessing
error pointer is also fixed.

When a buffer is evicted for memory pressure or TTM evict all,
the placement is set to the eviction domain, this means the
buffer never gets revalidated on the next exec to the correct domain.
I think this should be fine to use the initial domain from the
object creation, as least with VM_BIND this won't change after
init so this should be the correct answer.

We had a report that iptables-restore sometimes triggered null-ptr-deref
at boot time. [0]
The problem is that iptable_nat_table_init() is exposed to user space
before the kernel fully initialises netns.
In the small race window, a user could call iptable_nat_table_init()
that accesses net_generic(net, iptable_nat_net_id), which is available
only after registering iptable_nat_net_ops.
Let's call register_pernet_subsys() before xt_register_template().

Commit in Fixes was added as a catch-all for cases where the cmdline is
parsed before being merged with the builtin one.
And promptly one issue appeared, see Link below. The microcode loader
really needs to parse it that early, but the merging happens later.
Reshuffling the early boot nightmare^W code to handle that properly would
be a painful exercise for another day so do the chicken thing and parse the
builtin cmdline too before it has been merged.

The recent regression report revealed that the use of WC pages for AMD
HDMI device together with AMD IOMMU leads to unexpected truncation or
noises. The issue seems triggered by the change in the kernel core
memory allocation that enables IOMMU driver to use always S/G
buffers. Meanwhile, the use of WC pages has been a workaround for the
similar issue with standard pages in the past. So, now we need to
apply the workaround conditionally, namely, only when IOMMU isn't in
place.
This patch modifies the workaround code to check the DMA ops at first
and apply the snoop-off only when needed.

David Laight pointed out that we should deal with the min3() and max3()
mess too, which still does excessive expansion.
And our current macros are actually rather broken.
In particular, the macros did this:
#define min3(x, y, z) min((typeof(x))min(x, y), z)
#define max3(x, y, z) max((typeof(x))max(x, y), z)
and that not only is a nested expansion of possibly very complex
arguments with all that involves, the typing with that "typeof()" cast
is completely wrong.
For example, imagine what happens in max3() if 'x' happens to be a
'unsigned char', but 'y' and 'z' are 'unsigned long'. The types are
compatible, and there's no warning - but the result is just random
garbage.
No, I don't think we've ever hit that issue in practice, but since we
now have sane infrastructure for doing this right, let's just use it.
It fixes any excessive expansion, and also avoids these kinds of broken
type issues.

The Linux-internal Xlinuxenvcfg ISA extension is omitted from the
riscv_isa_ext array because it has no DT binding and should not appear
in /proc/cpuinfo. The logic added in commit 625034abd52a ("riscv: add
ISA extensions validation callback") assumes all extensions are included
in riscv_isa_ext, and so riscv_resolve_isa() wrongly drops Xlinuxenvcfg
from the final ISA string. Instead, accept such Linux-internal ISA
extensions as if they have no validation callback.

As explained in the previous patch, the MST link BW reported by branch
devices during topology probing/path resources enumeration depends on
the link parameters programmed to DPCD to be up-to-date. After a sink is
plugged this is not ensured, as those DPCD values start out zeroed. The
target link parameters (for a subsequent modeset) are the maximum that
is supported, so make sure these maximum values are programmed before the
topology probing.

The MST link BW reported by branch devices via the ENUM_PATH_RESOURCES
message depends on the channel coding and link rate/lane count
parameters programmed to DPCD. This is the case at least for some branch
devices, while for others the reported BW is independent of the link
parameters. In any case the DP standard requires the branch device to
adjust the returned value to both account for the different way the BW
for FEC is accounted for (included in the returned value for non-UHBR
and not included for UHBR rates) and to limit the returned value to the
(trained) link BW between the source and first downstream branch
device, see DP v2.0/v2.1 Figure 2-94, DP v2.1 5.9.7. Presumedly this is
also the reason why the standard requires the DPCD link rate/lane count
values being up-to-date before sending the ENUM_PATH_RESOURCES message,
see DP v2.1 2.14.9.4.
Based on the above reprobe the MST topology after the link is retrained
with new link parameters to make sure that the MST link BW tracked in
the MST topology state (via each topology port's full_pbn value) is
up-to-date.
The next patch will make sure that the MST link BW is also kept
up-to-date if the link is disabled.

On MST links - at least for some MST branch devices - the list of modes
returned to users on an enabled link depends on the current link
rate/lane count parameters (besides the DPRX link capabilities, any MST
branch BW limit and the maximum link parameters reduced after LT
failures). In particular the MST branch BW limit may depend on the link
rate/lane count parameters programmed to DPCD. After an LT failure and
limiting the maximum link parameters accordingly, users should see a
mode list reflecting these new limits. However with the current fallback
order this isn't ensured, as the new limit could allow for modes
requiring a higher link BW, but these modes will be filtered out due to
the enabled link's lower link BW.
Ensure that the mode list changes in a consistent way after a link
training failure and reducing the link parameters by changing the
fallback order on MST links to happen in BW order.
v2:
- s/INTEL_DP_MAX_SUPPORTED_LANE_COUNTS/INTEL_DP_MAX_SUPPORTED_LANE_CONFIGS
and s/num_common_lane_counts/num_common_lane_configs to make the
difference wrt. max lane counts clearer. (Suraj)
- Add a TODO comment to make the SST fallback logic work the same way as
MST. (Arun)
- Use sort_r()'s default swap function instead of a custom one.

sent to all the connectors on the link, so in case of multiple failures

In the
if (old_ddps != port->ddps || !created)
if (port->ddps && !port->input)
ret = drm_dp_send_enum_path_resources();
sequence the first if's condition is true if the port exists already
(!created) or the port was created anew (hence old_ddps==0) and it was
in the plugged state (port->ddps==1). The second if's condition is true
for output ports in the plugged state. So the function is called for an
output port in the plugged state, regardless if it already existed or
not and regardless of the old plugged state. In all other cases
port->full_pbn can be zeroed as the port is either an input for which
full_pbn is never set, or an output in the unplugged state for which
full_pbn was already zeroed previously or the port was just created
(with port->full_pbn==0).
Simplify the condition, making it clear that the path resources are
always enumerated for an output port in the plugged state.
