In order to function, the IPA driver very clearly requires the
interconnect framework to be enabled in the kernel configuration.
State that dependency in the Kconfig file.
This became a problem when CONFIG_COMPILE_TEST support was added.
Non-Qualcomm platforms won't necessarily enable CONFIG_INTERCONNECT.

40GbE Intel Wired LAN Driver Updates 2022-03-01
This series contains updates to iavf driver only.
Mateusz adds support for interrupt moderation for 50G and 100G speeds
as well as support for the driver to specify a request as its primary
MAC address. He also refactors VLAN V2 capability exchange into more
generic extended capabilities to ease the addition of future
capabilities. Finally, he corrects the incorrect return of iavf_status
values and removes non-inclusive language.
Minghao Chi removes unneeded variables, instead returning values
directly.

The truesize for a UDP GRO packet is added by main skb and skbs in main
skb's frag_list:
skb_gro_receive_list
p->truesize += skb->truesize;
The commit 53475c5dd8 ("net: fix use-after-free when UDP GRO with
shared fraglist") introduced a truesize increase for frag_list skbs.
When uncloning skb, it will call pskb_expand_head and trusesize for
frag_list skbs may increase. This can occur when allocators uses
__netdev_alloc_skb and not jump into __alloc_skb. This flow does not
use ksize(len) to calculate truesize while pskb_expand_head uses.
skb_segment_list
err = skb_unclone(nskb, GFP_ATOMIC);
pskb_expand_head
if (!skb->sk || skb->destructor == sock_edemux)
skb->truesize += size - osize;
If we uses increased truesize adding as delta_truesize, it will be
larger than before and even larger than previous total truesize value
if skbs in frag_list are abundant. The main skb truesize will become
smaller and even a minus value or a huge value for an unsigned int
parameter. Then the following memory check will drop this abnormal skb.
To avoid this error we should use the original truesize to segment the
main skb.

when ext4 filesystem is created with 64k block size, ^extent and
^huge_file features. the upper_limit would underflow during the
computations in ext4_max_bitmap_size(). The problem is the size of block
index tree for such large block size is more than i_blocks can carry.
So fix the computation to count with this possibility. After this fix,
the 'res' cannot overflow loff_t on the extreme case of filesystem with
huge_files and 64K block size, so this patch also revert commit

The new registration method allows to get power values from the DT OPP
definition. The new OPP entry property "opp-microwatt" contains total

The Energy Model (EM) can be created based on DT entry:
'dynamic-power-coefficient'. It's a 'simple' EM which is limited to the
dynamic power. It has to fit into the math formula which requires also
information about voltage. Some of the platforms don't expose voltage
information, thus it's not possible to use EM registration using DT.
This patch aims to fix it. It introduces new implementation of the EM
registration callback. The new mechanism relies on the new OPP feature
allowing to get power (which is coming from "opp-microwatt" DT property)
expressed in micro-Watts.
The patch also opens new opportunity to better support platforms, which
have a decent static power. It allows to register the EM based on real
power measurements which models total power (static + dynamic), so better
reflects real HW.

This will allow to enable the tests only after latest fix
after which the tests passed on my system.
I tested on NV21 standalone and Vega 10 and Polaris as
pair with DRI_PRIME.
It's possible there might be still issues on ASICs i don't
have at my posession but that that the point of enbling
the tests finally - if other people during testing will
encounter errors they will report and I will be able to fix.
The releated merge request for enabling libdrm tests suite is in

1. Define amdgpu_ras_block_late_fini_default in amdgpu_ras.c as
.ras_fini common function, which is called when
.ras_fini of ras block isn't initialized.
2. Remove the code of using amdgpu_ras_block_late_fini to
initialize .ras_fini in ras blocks.
