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.

Currently, the psample netlink skb is allocated with a size that does
not account for the nested 'PSAMPLE_ATTR_TUNNEL' attribute and the
padding required for the 64-bit attribute 'PSAMPLE_TUNNEL_KEY_ATTR_ID'.
This can result in failure to add attributes to the netlink skb due
to insufficient tail room. The following error message is printed to
the kernel log: "Could not create psample log message".

Fix this by adjusting the allocation size to take into account the
nested attribute and the padding.

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.

Pull x86 irq entry updates from Thomas Gleixner:
 "The irq stack switching was moved out of the ASM entry code in course
  of the entry code consolidation. It ended up being suboptimal in
  various ways.

  This reworks the X86 irq stack handling:

   - Make the stack switching inline so the stackpointer manipulation is
     not longer at an easy to find place.

   - Get rid of the unnecessary indirect call.

   - Avoid the double stack switching in interrupt return and reuse the
     interrupt stack for softirq handling.

   - A objtool fix for CONFIG_FRAME_POINTER=y builds where it got
     confused about the stack pointer manipulation"

__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 20dd3850 ("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.
