The RTL8401-internal PHY identifies as RTL8201CP, and the init
sequence in r8169, copied from vendor driver r8168, uses paged
operations. Therefore set the same paged operation callbacks as
for the other Realtek PHY's.

Commit 6f197fb63850 ("lan743x: Added fixed link and RGMII support")
assumes that chips with an internal PHY will never have a devicetree
entry. This is incorrect: even for these chips, a devicetree entry
can be useful e.g. to pass the mac address from bootloader to chip:
&pcie {
status = "okay";
host@0 {
reg = <0 0 0 0 0>;
#address-cells = <3>;
#size-cells = <2>;
lan7430: ethernet@0 {
/* LAN7430 with internal PHY */
compatible = "microchip,lan743x";
status = "okay";
reg = <0 0 0 0 0>;
/* filled in by bootloader */
local-mac-address = [00 00 00 00 00 00];
};
};
};
If a devicetree entry is present, the driver will not attach the chip
to its internal phy, and the chip will be non-operational.
Fix by tweaking the phy connection algorithm:
- first try to connect to a phy specified in the devicetree
(could be 'real' phy, or just a 'fixed-link')
- if that doesn't succeed, try to connect to an internal phy, even
if the chip has a devnode
Tested on a LAN7430 with internal PHY. I cannot test a device using
fixed-link, as I do not have access to one.

Fix MAC setting flow for the PF driver.
Update the unicast VF's MAC address in VF structure if it is
a new setting in i40e_vc_add_mac_addr_msg.
When unicast MAC address gets deleted, record that and
set the new unicast MAC address that is already waiting in the filter
list. This logic is based on the order of messages arriving to
the PF driver.
Without this change the MAC address setting was interpreted
incorrectly in the following use cases:
1) Print incorrect VF MAC or zero MAC
ip link show dev $pf
2) Don't preserve MAC between driver reload
rmmod iavf; modprobe iavf
3) Update VF MAC when macvlan was set
ip link add link $vf address $mac $vf.1 type macvlan
4) Failed to update mac address when VF was trusted
ip link set dev $vf address $mac

Remove non-privileged user access to power data contained in
/sys/class/powercap/intel-rapl*/*/energy_uj
Non-privileged users currently have read access to power data and can
use this data to form a security attack. Some privileged
drivers/applications need read access to this data, but don't expose it
to non-privileged users.
For example, thermald uses this data to ensure that power management
works correctly. Thus removing non-privileged access is preferred over
completely disabling this power reporting capability with

When GPIOs that are routed to PDC are used as output they can still latch
the IRQ pending at GIC. As a result the spurious IRQ was handled when the
client driver change the direction to input to starts using it as IRQ.
Currently such erroneous latched IRQ are cleared with .irq_enable callback
however if the driver continue to use GPIO as interrupt and invokes
disable_irq() followed by enable_irq() then everytime during enable_irq()
previously latched interrupt gets cleared.
This can make edge IRQs not seen after enable_irq() if they had arrived
after the driver has invoked disable_irq() and were pending at GIC.
Move clearing erroneous IRQ to .irq_request_resources callback as this is
the place where GPIO direction is changed as input and its locked as IRQ.
While at this add a missing check to invoke msm_gpio_irq_clear_unmask()
from .irq_enable callback only when GPIO is not routed to PDC.

When powering off a card, we need to disable the tuning HW (like SCC for
the Renesas SDHI) to get to a sane state and allow for re-tuning new
cards. This was hidden before because we wrongly did that in hw_reset()
before which was an unintended use of hw_reset(). Now that we corrected
the use of hw_reset() meanwhile, we revealed this shortcoming and need
to fix it properly by explicitly calling the downgrade callback.

The Medion Akoya E2228T's ACPI _LID implementation is quite broken,
it has the same issues as the one from the Medion Akoya E2215T:
1. For notifications it uses an ActiveLow Edge GpioInt, rather then
an ActiveBoth one, meaning that the device is only notified when the
lid is closed, not when it is opened.
2. Matching with this its _LID method simply always returns 0 (closed)
In order for the Linux LID code to work properly with this implementation,
the lid_init_state selection needs to be set to ACPI_BUTTON_LID_INIT_OPEN,
add a DMI quirk for this.
While working on this I also found out that the MD60### part of the model
number differs per country/batch while all of the E2215T and E2228T models
have this issue, so also remove the " MD60198" part from the E2215T quirk.

Replace the resulting undefined behavior with an error return.
This may break some things that happen to work at the moment
but seems better than randomly overwriting kernel data.
I assume we need additional fixes for the two functions that now
return an error.

We thus should not schedule() at all, even with timeout == 0, this
crashes the kernel. We can however use try_wait_for_completion()

speakup_cut() calls speakup_clear_selection() which calls console_lock.
Problem is: speakup_cut() is called from a keyboard interrupt
context. This would hang if speakup_cut is pressed while the console
lock is unfortunately already held.
We can however as well just defer calling clear_selection() until the
already-deferred set_selection_kernel() call.
This was spotted by the lock hardener:

commit d97a9d7aea04 ("staging/speakup: Add inflection synth parameter")
introduced a new "inflection" speakup parameter next to "pitch", but
the values of the var_id_t enum are actually used by the keymap tables
so we must not renumber them. The effect was that notably the volume
control shortcut (speakup-1 or 2) was actually changing the inflection.
This moves the INFLECTION value at the end of the var_id_t enum to
fix back the enum values. This also adds a warning about it.

Since commit 086d08725d34 ("remoteproc: create vdev subdevice with
specific dma memory pool"), every remoteproc has a DMA subdevice
("remoteprocX#vdevYbuffer") for each virtio device, which inherits
DMA capabilities from the corresponding platform device. This allowed
to associate different DMA pools with each vdev, and required from
virtio drivers to perform DMA operations with the parent device
(vdev->dev.parent) instead of grandparent (vdev->dev.parent->parent).
virtio_rpmsg_bus was already changed in the same merge cycle with
commit d999b622fcfb ("rpmsg: virtio: allocate buffer from parent"),
but virtio_console did not. In fact, operations using the grandparent
worked fine while the grandparent was the platform device, but since
commit c774ad010873 ("remoteproc: Fix and restore the parenting
hierarchy for vdev") this was changed, and now the grandparent device
is the remoteproc device without any DMA capabilities.
So, starting v5.8-rc1 the following warning is observed:
[ 2.483925] ------------[ cut here ]------------

obviously because the grandparent now is remoteproc dev without any
DMA caps:
[ 3.104943] Parent: remoteproc0#vdev1buffer, grandparent: remoteproc0
Fix this the same way as it was for virtio_rpmsg_bus, using just the
parent device (vdev->dev.parent, "remoteprocX#vdevYbuffer") for DMA
operations.
This also allows now to reserve DMA pools/buffers for rproc serial
via Device Tree.
