After we introduced a module parameter and quirk infrastructure for
picking the Microsoft GUID over the SOC vendor GUID we discovered
that lots and lots of systems are getting this wrong.
The table continues to grow, and is becoming unwieldy.
We don't really have any benefit to forcing vendors to populate the
AMD GUID. This is just extra work, and more and more vendors seem
to mess it up. As the Microsoft GUID is used by Windows as well,
it's very likely that it won't be messed up like this.
So drop all the quirks forcing it and the Rembrandt behavior. This
means that Cezanne or later effectively only run the Microsoft GUID
codepath with the exception of HP Elitebook 8*5 G9.

HP Elitebook 865 supports both the AMD GUID w/ _REV 2 and Microsoft
GUID with _REV 0. Both have very similar code but the AMD GUID
has a special workaround that is specific to a problem with
spurious wakeups on systems with Qualcomm WLAN.
This is believed to be a bug in the Qualcomm WLAN F/W (it doesn't
affect any other WLAN H/W). If this WLAN firmware is fixed this
quirk can be dropped.

The apple-gmux driver only binds to old GMUX devices which have an
IORESOURCE_IO resource (using inb()/outb()) rather then memory-mapped
IO (IORESOURCE_MEM).
T2 MacBooks use the new style GMUX devices (with IORESOURCE_MEM access),
so these are not supported by the apple-gmux driver. This is not a problem
since they have working ACPI video backlight support.
But the apple_gmux_present() helper only checks if an ACPI device with
the "APP000B" HID is present, causing acpi_video_get_backlight_type()
to return acpi_backlight_apple_gmux disabling the acpi_video backlight
device.
Add a new apple_gmux_backlight_present() helper which checks that
the "APP000B" device actually is an old GMUX device with an IORESOURCE_IO
resource.
This fixes the acpi_video0 backlight no longer registering on T2 MacBooks.
Note people are working to add support for the new style GMUX to Linux:
https://github.com/kekrby/linux-t2/commits/wip/hybrid-graphics
Once this lands this patch should be reverted so that
acpi_video_get_backlight_type() also prefers the gmux on new style GMUX
MacBooks, but for now this is necessary to avoid regressing backlight
control on T2 Macs.

The ACPI video detection code has a module parameter
`register_backlight_delay` which is currently configured to 8 seconds.
This means that if after 8 seconds of booting no native driver has created
a backlight device then the code will attempt to make an ACPI video
backlight device.
This was intended as a safety mechanism with the backlight overhaul that
occurred in kernel 6.1, but as it doesn't appear necesssary set it to be
disabled by default.

On desktop APUs amdgpu doesn't create a native backlight device
as no eDP panels are found. However if the BIOS has reported
backlight control methods in the ACPI tables then an acpi_video0
backlight device will be made 8 seconds after boot.
This has manifested in a power slider on a number of desktop APUs
ranging from Ryzen 5000 through Ryzen 7000 on various motherboard
manufacturers. To avoid this, report to the acpi video detection
that the system does not have any panel connected in the native
driver.

The current logic for the ACPI backlight detection will create
a backlight device if no native or vendor drivers have created
8 seconds after the system has booted if the ACPI tables
included backlight control methods.
If the GPU drivers have loaded, they may be able to report whether
any LCD panels were found. Allow using this information to factor
in whether to enable the fallback logic for making an acpi_video0
backlight device.

When AF_XDP is used on on a veth interface the RX ring is updated in two
steps. veth_xdp_rcv() removes packet descriptors from the FILL ring
fills them and places them in the RX ring updating the cached_prod
pointer. Later xdp_do_flush() syncs the RX ring prod pointer with the
cached_prod pointer allowing user-space to see the recently filled in
descriptors. The rings are intended to be SPSC, however the existing
order in veth_poll allows the xdp_do_flush() to run concurrently with
another CPU creating a race condition that allows user-space to see old
or uninitialized descriptors in the RX ring. This bug has been observed
in production systems.
To summarize, we are expecting this ordering:
CPU 0 __xsk_rcv_zc()
CPU 0 __xsk_map_flush()
CPU 2 __xsk_rcv_zc()
CPU 2 __xsk_map_flush()
But we are seeing this order:
CPU 0 __xsk_rcv_zc()
CPU 2 __xsk_rcv_zc()
CPU 0 __xsk_map_flush()
CPU 2 __xsk_map_flush()
This occurs because we rely on NAPI to ensure that only one napi_poll
handler is running at a time for the given veth receive queue.
napi_schedule_prep() will prevent multiple instances from getting
scheduled. However calling napi_complete_done() signals that this
napi_poll is complete and allows subsequent calls to
napi_schedule_prep() and __napi_schedule() to succeed in scheduling a
concurrent napi_poll before the xdp_do_flush() has been called. For the
veth driver a concurrent call to napi_schedule_prep() and
__napi_schedule() can occur on a different CPU because the veth xmit
path can additionally schedule a napi_poll creating the race.
The fix as suggested by Magnus Karlsson, is to simply move the
xdp_do_flush() call before napi_complete_done(). This syncs the
producer ring pointers before another instance of napi_poll can be
scheduled on another CPU. It will also slightly improve performance by
moving the flush closer to when the descriptors were placed in the
RX ring.

When the PCS was taken out of reset, we were changing by mistake also
the speed to 100 Mbit. But in case the link was going down, the link
up routine was setting correctly the link speed. If the link was not
getting down then the speed was forced to run at 100 even if the
speed was something else.
On lan966x, to set the speed link to 1G or 2.5G a value of 1 needs to be
written in DEV_CLOCK_CFG_LINK_SPEED. This is similar to the procedure in
lan966x_port_init.
The issue was reproduced using 1000base-x sfp module using the commands:
ip link set dev eth2 up
ip link addr add 10.97.10.2/24 dev eth2
ethtool -s eth2 speed 1000 autoneg off

Multicast packets received on an interface bound to a VRF are marked as
belonging to the VRF and the skb device is updated to point to the VRF
device itself. This was fine even when a route was associated to a
device as when performing a fib table lookup 'oif' in fib6_table_lookup
(coming from 'skb->dev->ifindex' in ip6_route_input) was set to 0 when
FLOWI_FLAG_SKIP_NH_OIF was set.
With commit 40867d74c374 ("net: Add l3mdev index to flow struct and
avoid oif reset for port devices") this is not longer true and multicast
traffic is not received on the original interface.
Instead of adding back a similar check in fib6_table_lookup determine
the dst using the original ifindex for multicast VRF traffic. To make
things consistent across the function do the above for all strict
packets, which was the logic before commit 6f12fa775530 ("vrf: mark skb
for multicast or link-local as enslaved to VRF"). Note that reverting to
this behavior should be fine as the change was about marking packets
belonging to the VRF, not about their dst.

Previously ice XDP xmit routine was changed in a way that it avoids
xdp_buff->xdp_frame conversion as it is simply not needed for handling
XDP_TX action and what is more it saves us CPU cycles. This routine is
re-used on ZC driver to handle XDP_TX action.
Although for XDP_TX on Rx ZC xdp_buff that comes from xsk_buff_pool is
converted to xdp_frame, xdp_frame itself is not stored inside
ice_tx_buf, we only store raw data pointer. Casting this pointer to
xdp_frame and calling against it xdp_return_frame in
ice_clean_xdp_tx_buf() results in undefined behavior.
To fix this, simply call page_frag_free() on tx_buf->raw_buf.
Later intention is to remove the buff->frame conversion in order to
simplify the codebase and improve XDP_TX performance on ZC.

Pull more random number generator updates from Jason Donenfeld:
"Two remaining changes that are now possible after you merged a few
other trees:
- #include <asm/archrandom.h> can be removed from random.h now,
making the direct use of the arch_random_* API more of a private
implementation detail between the archs and random.c, rather than
something for general consumers.
- Two additional uses of prandom_u32_max() snuck in during the
initial phase of pulls, so these have been converted to
get_random_u32_below(), and now the deprecated prandom_u32_max()
alias -- which was just a wrapper around get_random_u32_below() --
can be removed.
In addition, there is one fix:
- Check efi_rt_services_supported() before attempting to use an EFI
runtime function.
This affected EFI systems that disable runtime services yet still
boot via EFI (e.g. the reporter's Lenovo Thinkpad X13s laptop), as
well systems where EFI runtime services have been forcibly
disabled, such as on PREEMPT_RT.
On those machines, a very early and hard to diagnose crash would
happen, preventing boot"

panfrost_gem_create_with_handle() previously returned a BO but with the
only reference being from the handle, which user space could in theory
guess and release, causing a use-after-free. Additionally if the call to
panfrost_gem_mapping_get() in panfrost_ioctl_create_bo() failed then
a(nother) reference on the BO was dropped.
The _create_with_handle() is a problematic pattern, so ditch it and
instead create the handle in panfrost_ioctl_create_bo(). If the call to
panfrost_gem_mapping_get() fails then this means that user space has
indeed gone behind our back and freed the handle. In which case just
return an error code.

Convert the max size to bytes to match the units of the divisor that
calculates the worst-case number of PRP entries.
The result is used to determine how many PRP Lists are required. The
code was previously rounding this to 1 list, but we can require 2 in the
worst case. In that scenario, the driver would corrupt memory beyond the
size provided by the mempool.
While unlikely to occur (you'd need a 4MB in exactly 127 phys segments
on a queue that doesn't support SGLs), this memory corruption has been
observed by kfence.

When using shadow doorbells, the event index and the doorbell values are
written to host memory. Prior to this patch, the values written would
erroneously be written in host endianness. This causes trouble on
big-endian platforms. Fix this by adding missing endian conversions.
This issue was noticed by Guenter while testing various big-endian
platforms under QEMU[1]. A similar fix required for hw/nvme in QEMU is
up for review as well[2].

The build_skb might return a null pointer but there is no check on the
return value in the fec_enet_rx_queue(). So a null pointer dereference
might occur. To avoid this, we check the return value of build_skb. If
the return value is a null pointer, the driver will recycle the page and
update the statistic of ndev. Then jump to rx_processing_done to clear
the status flags of the BD so that the hardware can recycle the BD.

MES is part of gfxoff and MES suspend and resume are skipped for S0i3.
But the mes_self_test call path is still in the amdgpu_device_ip_late_init.
it's should also be skipped for s0ix as no hardware re-initialization
happened.
Besides, mes_self_test will free the BO that triggers a lot of warning

If kfd_process_device_init_vm returns failure after vm is converted to

Should only destroy the ib_mem and let process cleanup worker to free
the outstanding BOs. Reset the pointer in pdd->qpd structure, to avoid
NULL pointer access in process destroy worker.

MES is part of gfxoff and MES suspend and resume are skipped for S0i3.
But the mes_self_test call path is still in the amdgpu_device_ip_late_init.
it's should also be skipped for s0ix as no hardware re-initialization
happened.
Besides, mes_self_test will free the BO that triggers a lot of warning
messages while in the suspend state.

[Why]
connector hdcp properties are lost after display is
unplgged from mst hub. connector is destroyed with
dm_dp_mst_connector_destroy. when display is plugged
back, hdcp is not desired and it wouldnt be enabled.
[How]
save hdcp properties into hdcp_work within
amdgpu_dm_atomic_commit_tail. If the same display is
plugged back with same display index, its hdcp
properties will be retrieved from hdcp_work within
dm_dp_mst_get_modes.
