Instead of having a global flag to require restricted memory access
for all virtio devices, introduce a callback which can select that
requirement on a per-device basis.
For convenience add a common function returning always true, which can
be used for use cases like SEV.
Per default use a callback always returning false.
As the callback needs to be set in early init code already, add a
virtio anchor which is builtin in case virtio is enabled.

Currently when the toolstack issues a reboot, it gets translated into a
call to ctrl_alt_del(). But tying reboot to ctrl-alt-del means rebooting
may fail if e.g. the user has masked the ctrl-alt-del.target under
systemd.
A previous attempt to fix this issue made a change that sets the
kernel.ctrl-alt-del sysctl to 1 before ctrl_alt_del() is called.
However, this doesn't give userspace the opportunity to block rebooting
or even do any cleanup or syncing.
Instead, call orderly_reboot() which will call the "reboot" command,
giving userspace the opportunity to block it or perform the usual reboot
process while being independent of the ctrl-alt-del behaviour. It also
matches what happens in the shutdown case.

Set ret to 0 (success) before entering first if statement, thereby
assuring that even if the device is not associated and further checks
pass, we do not then end up returning the uninitialized value of ret.
This assignment is deliberately now directly before the if statement, in
order to keep it clear what is happening as opposed to having it as an
initialization at the start of the function like it was originally.
Also add a comment to make it clear this first if block is currently a
success path. As a side note, smatch does not trigger warnings for this
change, for me at least.
Within core/rtw_pwrctrl.c in the rtw_pwr_wakeup function, I previously
dropped the initialization of 'ret' (int ret = 0;) in favour of its
assignment which happens inside the first if block directly before its
corresponding goto. This was the cause of this bug, and was introduced
by: commit f3a76018dd55 ("staging: r8188eu: remove initializer from ret

Representors do not want to be subject to the PF's Ethernet address
filters, since traffic from VFs will typically have a destination
either elsewhere on the link segment or on an overlay network.
So, create a dynamic m-port with promiscuous and all-multicast
filters, and set it as the egress port of representor default rules.
Since the m-port is an alias of the calling PF's own m-port, traffic
will still be delivered to the PF's RXQs, but it will be subject to
the VNRX filter rules installed on the dynamic m-port (specified by
the v-port ID field of the filter spec).

We need to be able to drop the efx->filter_sem in ef100_filter_table_up()
so that we can call functions that insert filters (and thus take that
rwsem for read), which means the efx->type->filter_table_probe method
needs to be responsible for taking the lock in the first place.

Default rules are low-priority switching rules which the hardware uses
in the absence of higher-priority rules. Each representor requires a
corresponding rule matching traffic from its representee VF and
delivering to the PF (where a check on INGRESS_MPORT in
__ef100_rx_packet() will direct it to the representor). No rule is
required in the reverse direction, because representor TX uses a TX
override descriptor to bypass the MAE and deliver directly to the VF.
Since inserting any rule into the MAE disables the firmware's own
default rules, also insert a pair of rules to connect the PF to the
physical network port and vice-versa.

Traffic delivered to the (MAE admin) PF could be from either the wire
or a VF. The INGRESS_MPORT field of the RX prefix distinguishes these;
base_mport is the value this field will have for traffic from the wire
(which should be delivered to the PF's netdevice, not a representor).

Representor RX uses a NAPI context driven by a 'fake interrupt': when
the parent PF receives a packet destined for the representor, it adds
it to an SKB list (efv->rx_list), and schedules NAPI if the 'fake
interrupt' is primed. The NAPI poll then pulls packets off this list
and feeds them to the stack with netif_receive_skb_list().
This scheme allows us to decouple representor RX from the parent PF's
RX fast-path.
This patch implements the 'top half', which builds an SKB, copies data
into it from the RX buffer (which can then be released), adds it to
the queue and fires the 'fake interrupt' if necessary.

We got a report from Stephen/Michael that the PowerPC build was failing
with the following error:
ld: drivers/gpu/drm/amd/display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o uses soft float
ld: failed to merge target specific data of file drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o
This error happened because of the function optc3_set_vrr_m_const. This
function expects a double as a parameter in a code that is not allowed
to have FPU operations. After further investigation, it became clear
that optc3_set_vrr_m_const was never invoked, so we can safely drop this
function and fix the ld issue.

Merge series from nick.hawkins@hpe.com <nick.hawkins@hpe.com>:
The GXP supports 3 separate SPI interfaces to accommodate the system
flash, core flash, and other functions. The SPI engine supports variable
clock frequency, selectable 3-byte or 4-byte addressing and a
configurable x1, x2, and x4 command/address/data modes. The memory
buffer for reading and writing ranges between 256 bytes and 8KB. This
driver supports access to the core flash and bios part.

Allow ASPM L1 and its substates. By default this is disabled in the qcom
specific hardware. Enable it explicitly only for controllers belonging to
2_7_0.
This does not affect any link capability registers; it will allow the link
transitions to L1 and its substates only if they are already supported.
