This patch fixes a bug where GEN1 VMs doesn't allow resolutions greater
than 64 MB size (eg 7680x4320). Unnecessary PCI check limits Gen1 VRAM
to legacy PCI BAR size only (ie 64MB). Thus any, resolution requesting
greater then 64MB (eg 7680x4320) would fail. MMIO region assigning this
memory shouldn't be limited by PCI bar size.

When returning to user space, %rsp is user-controlled value.
If it is a SNP-guest and the hypervisor decides to mess with the
code-page for this path while a CPU is executing it, a potential #VC
could hit in the syscall return path and mislead the #VC handler.
So make ip_within_syscall_gap() return true in this case.

It is possible to stack bridges on top of each other. Consider the
following which makes use of an Ethernet switch:
br1
/ \
/ \
/ \
br0.11 wlan0
|
br0
/ | \
p1 p2 p3
br0 is offloaded to the switch. Above br0 is a vlan interface, for
vlan 11. This vlan interface is then a slave of br1. br1 also has a
wireless interface as a slave. This setup trunks wireless lan traffic
over the copper network inside a VLAN.
A frame received on p1 which is passed up to the bridge has the
skb->offload_fwd_mark flag set to true, indicating that the switch has
dealt with forwarding the frame out ports p2 and p3 as needed. This
flag instructs the software bridge it does not need to pass the frame
back down again. However, the flag is not getting reset when the frame
is passed upwards. As a result br1 sees the flag, wrongly interprets
it, and fails to forward the frame to wlan0.
When passing a frame upwards, clear the flag. This is the Rx
equivalent of br_switchdev_frame_unmark() in br_dev_xmit().

In the detach path, the driver calls sysfs_remove_group() for the
groups it believes has been registered. However, if the group was
never previously registered, then this causes a splat.
Instead, compute the groups that should be registered in advance,
and then call sysfs_create_groups(), which registers them all at once.
Update the error handling appropriately.

Introduce a new loop index, 'j', in order to simplify the error handling

It is now written with the same logic and intermediate variables used

adin: add support for clock output
This patch series adds support for configuring the two clock outputs of adin
1200 and 1300 PHYs. Certain network controllers require an external reference
clock which can be provided by the PHY.
One of the replies to v1 was asking why the common clock framework isn't used.
Currently no PHY driver has implemented providing a clock to the network
controller. Instead they rely on vendor extensions to make the appropriate
configuration. For example ar8035 uses qca,clk-out-frequency - this patchset
aimed to replicate the same functionality.
Finally the 125MHz free-running clock is enabled in the device-tree for
SolidRun i.MX6 SoMs, to support revisions 1.9 and later, where the original phy
has been replaced with an adin 1300.
To avoid introducing new warning messages during boot for SoMs before rev 1.9,
the status field of the new phy node is disabled by default, and will be
enabled by U-Boot on demand.

Since SoM revision 1.9 the PHY has been replaced with an ADIN1300,
add an entry for it next to the original.
As Russell King pointed out, additional phy nodes cause warnings like:
mdio_bus 2188000.ethernet-1: MDIO device at address 1 is missing
To avoid this the new node has its status set to disabled. U-Boot will
be modified to enable the appropriate phy node after probing.
The existing ar8035 nodes have to stay enabled by default to avoid
breaking existing systems when they update Linux only.

The ADIN1300 supports generating certain clocks on its GP_CLK pin, as
well as providing the reference clock on CLK25_REF.
Add support for selecting the clock via device-tree properties.
Technically the phy also supports a recovered 125MHz clock for
synchronous ethernet. SyncE should be configured dynamically at
runtime, however Linux does not currently have a toggle for this,
so support is explicitly omitted.

Netfilter fixes for net
1) Reduce number of hardware offload retries from flowtable datapath
which might hog system with retries, from Felix Fietkau.
2) Skip neighbour lookup for PPPoE device, fill_forward_path() already
provides this and set on destination address from fill_forward_path for
PPPoE device, also from Felix.
4) When combining PPPoE on top of a VLAN device, set info->outdev to the
PPPoE device so software offload works, from Felix.
5) Fix TCP teardown flowtable state, races with conntrack gc might result
in resetting the state to ESTABLISHED and the time to one day. Joint
work with Oz Shlomo and Sven Auhagen.
6) Call dst_check() from flowtable datapath to check if dst is stale
instead of doing it from garbage collector path.
7) Disable register tracking infrastructure, either user-space or
kernel need to pre-fetch keys inconditionally, otherwise register
tracking assumes data is already available in register that might
not well be there, leading to incorrect reductions.

The TCU clock gate on X1000 wasn't requested by the driver and could
be gated automatically later on in boot, which prevents timers from
running and breaks PWM.
Add a workaround to support old device trees that don't specify the
"tcu" clock gate. In this case the kernel will print a warning and
attempt to continue without the clock, which is wrong, but it could
work if "clk_ignore_unused" is in the kernel arguments.
