Following a similar reinstate for the KSZ9031.
Older kernels would use the genphy_soft_reset if the PHY did not implement
a .soft_reset.
Bluntly removing that default may expose a lot of situations where various
PHYs/board implementations won't recover on various changes.
Like with this implementation during a 4.9.x to 5.4.x LTS transition.
I think it's a good thing to remove unwanted soft resets but wonder if it
did open a can of worms?
Atleast this fixes one iMX6 FEC/RMII/8081 combo.

sja1105_unpack() takes a "const void *buf" as its first parameter, so
there is no need to cast away the "const" of the "buf" variable before
calling it.
Drop the cast, as it prevents the compiler performing some checks.

heap name
By default dma_buf_export() sets the exporter name to be
KBUILD_MODNAME. Unfortunately this may not be identical to the
string used as the heap name (ie: "system" vs "system_heap").
This can cause some minor confusion with tooling, and there is
the future potential where multiple heap types may be exported
by the same module (but would all have the same name).
So to avoid all this, set the exporter exp_name to the heap name.

Really straighforward, only slight issue is that the sim connector is

Simple pipe helpers only have an enable and disable hook, no more
mode_set_nofb. Call it from our enable hook to align with that
conversions.
Atomic helpers always call mode_set_nofb and enable together, so
there's no functional change here.

dma-buf importing was reworked in commit 7d2cd72a9aa3
("drm/shmem-helpers: Simplify dma-buf importing"). Before that commit
drm_gem_shmem_prime_import_sg_table() did set ->pages_use_count=1 and
drm_gem_shmem_vunmap_locked() could call drm_gem_shmem_put_pages()
unconditionally. Now without the use count set, put pages is called also
on dma-bufs. Fix this by only putting pages if it's not imported.

The panel is able to work when dsi clock is non-continuous, thus
the system power consumption can be reduced using such feature.
Add MIPI_DSI_CLOCK_NON_CONTINUOUS to panel's mode_flags.
Also the flag actually becomes necessary after
commit c6d94e37bdbb ("drm/bridge/synopsys: dsi: add support for non-continuous HS clock")
and without it the panel only emits stripes instead of output.

The AFBC decoder used in the Rockchip VOP assumes the use of the
YUV-like colourspace transform (YTR). YTR is lossless for RGB(A)
buffers, which covers the RGBA8 and RGB565 formats supported in
vop_convert_afbc_format. Use of YTR is signaled with the
AFBC_FORMAT_MOD_YTR modifier, which prior to this commit was missing. As
such, a producer would have to generate buffers that do not use YTR,
which the VOP would erroneously decode as YTR, leading to severe visual
corruption.
The upstream AFBC support was developed against a captured frame, which
failed to exercise modifier support. Prior to bring-up of AFBC in Mesa
(in the Panfrost driver), no open userspace respected modifier
reporting. As such, this change is not expected to affect broken
userspaces.
Tested on RK3399 with Panfrost and Weston.

Many drivers reference the plane->state pointer in order to get the
current plane state in their atomic_update or atomic_disable hooks,
which would be the new plane state in the global atomic state since
_swap_state happened when those hooks are run.
Use the drm_atomic_get_new_plane_state helper to get that state to make it
more obvious.
This was made using the coccinelle script below:
@ plane_atomic_func @

static const struct drm_plane_helper_funcs helpers = {

.atomic_disable = func,

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.
The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.
Let's convert the remaining helpers to provide a consistent interface,
this time with the planes atomic_update and atomic_disable.
The conversion was done using the coccinelle script below, built tested on
all the drivers.

__ibmvnic_reset() currently reads the adapter->state before getting the
rtnl and saves that state as the "target state" for the reset. If this
read occurs when adapter is in PROBED state, the target state would be
PROBED.
Just after the target state is saved, and before the actual reset process
is started (i.e before rtnl is acquired) if we get an ibmvnic_open() call
we would move the adapter to OPEN state.
But when the reset is processed (after ibmvnic_open()) drops the rtnl),
it will leave the adapter in PROBED state even though we already moved
it to OPEN.
To fix this, use the RTNL to improve serialization when reading/updating
the adapter state. i.e determine the target state of a reset only after
getting the RTNL. And if a reset is in progress during an open, simply
set the target state of the adapter and let the reset code finish the
open (like we currently do if failover is pending).
One twist to this serialization is if the adapter state changes when we
drop the RTNL to update the link state. Account for this by checking if
there was an intervening open and update the target state for the reset
accordingly (see new comments in the code). Note that only the reset
functions and ibmvnic_open() can set the adapter to OPEN state and this
must happen under rtnl.

Since 20dd3850bcf8 ("can: Speed up CAN frame receiption by using
ml_priv") the CAN framework uses per device specific data in the AF_CAN
protocol. For this purpose the struct net_device->ml_priv is used. Later
the ml_priv usage in CAN was extended for other users, one of them being
CAN_J1939.
Later in the kernel ml_priv was converted to an union, used by other
drivers. E.g. the tun driver started storing it's stats pointer.
Since tun devices can claim to be a CAN device, CAN specific protocols
will wrongly interpret this pointer, which will cause system crashes.
Mostly this issue is visible in the CAN_J1939 stack.
To fix this issue, we request a dedicated CAN pointer within the
net_device struct.

This patch adds swapcache stat for the cgroup v2. The swapcache
represents the memory that is accounted against both the memory and the
swap limit of the cgroup. The main motivation behind exposing the
swapcache stat is for enabling users to gracefully migrate from cgroup
v1's memsw counter to cgroup v2's memory and swap counters.
Cgroup v1's memsw limit allows users to limit the memory+swap usage of a
workload but without control on the exact proportion of memory and swap.
Cgroup v2 provides separate limits for memory and swap which enables more
control on the exact usage of memory and swap individually for the
workload.
With some little subtleties, the v1's memsw limit can be switched with the
sum of the v2's memory and swap limits. However the alternative for memsw
usage is not yet available in cgroup v2. Exposing per-cgroup swapcache
stat enables that alternative. Adding the memory usage and swap usage and
subtracting the swapcache will approximate the memsw usage. This will
help in the transparent migration of the workloads depending on memsw
usage and limit to v2' memory and swap counters.
The reasons these applications are still interested in this approximate
memsw usage are: (1) these applications are not really interested in two
separate memory and swap usage metrics. A single usage metric is more
simple to use and reason about for them.
(2) The memsw usage metric hides the underlying system's swap setup from
the applications. Applications with multiple instances running in a
datacenter with heterogeneous systems (some have swap and some don't) will
keep seeing a consistent view of their usage.

Currently we use struct per_cpu_nodestat to cache the vmstat counters,
which leads to inaccurate statistics especially THP vmstat counters. In
the systems with hundreds of processors it can be GBs of memory. For
example, for a 96 CPUs system, the threshold is the maximum number of 125.
And the per cpu counters can cache 23.4375 GB in total.
The THP page is already a form of batched addition (it will add 512 worth
of memory in one go) so skipping the batching seems like sensible.
Although every THP stats update overflows the per-cpu counter, resorting
to atomic global updates. But it can make the statistics more accuracy
for the THP vmstat counters.
So we convert the NR_FILE_PMDMAPPED account to pages. This patch is
consistent with 8f182270dfec ("mm/swap.c: flush lru pvecs on compound page
arrival"). Doing this also can make the unit of vmstat counters more
unified. Finally, the unit of the vmstat counters are pages, kB and
bytes. The B/KB suffix can tell us that the unit is bytes or kB. The
rest which is without suffix are pages.
