The internal_hpd flag is set to true by dp_bridge_hpd_enable() and set to
false by dp_bridge_hpd_disable() to handle GPIO pinmuxed into DP controller
case. HDP related interrupts can not be enabled until internal_hpd is set
to true. At current implementation dp_display_config_hpd() will initialize
DP host controller first followed by enabling HDP related interrupts if
internal_hpd was true at that time. Enable HDP related interrupts depends on
internal_hpd status may leave system with DP driver host is in running state
but without HDP related interrupts being enabled. This will prevent external
display from being detected. Eliminated this dependency by moving HDP related
interrupts enable/disable be done at dp_bridge_hpd_enable/disable() directly
regardless of internal_hpd status.
Changes in V3:
-- dp_catalog_ctrl_hpd_enable() and dp_catalog_ctrl_hpd_disable()
-- rewording ocmmit text
Changes in V4:
-- replace dp_display_config_hpd() with dp_display_host_start()
-- move enable_irq() at dp_display_host_start();
Changes in V5:
-- replace dp_display_host_start() with dp_display_host_init()
Changes in V6:
-- squash remove enable_irq() and disable_irq()

ext4_xattr_block_set() relies on its caller to call dquot_initialize()
on the inode. To assure that this has happened there are WARN_ON
checks. Unfortunately, this is subject to false positives if there is
an antagonist thread which is flipping the file system at high rates
between r/o and rw. So only do the check if EXT4_XATTR_DEBUG is
enabled.

As per the new udp tunnel framework, drivers which need to know the
details of a port entry (i.e. port type) when it gets deleted should
use the .set_port / .unset_port callbacks.
Implementing the current .udp_tunnel_sync callback would mean that the
deleted tunnel port entry would be all zeros. This used to work on
older firmware because it would not check the input when deleting a
tunnel port. With newer firmware, the delete will now fail and
subsequent tunnel port allocation will fail as a result.

The firmware can send PHC_RTC_UPDATE async event on a PF that may not
have PTP registered. In such a case, there will be a null pointer
deference for bp->ptp_cfg when we try to handle the event.
Fix it by not registering for this event with the firmware if !bp->ptp_cfg.
Also, check that bp->ptp_cfg is valid before proceeding when we receive
the event.

Driver starts firmware fatal error recovery by detecting

We need to call bnxt_hwrm_func_qcfg() on a VF to query the default
VLAN that may be setup by the PF. If a default VLAN is enabled,
the VF cannot support VLAN acceleration on the receive side and
the VNIC must be setup to strip out the default VLAN tag. If a
default VLAN is not enabled, the VF can support VLAN acceleration
on the receive side. The VNIC should be set up to strip or not
strip the VLAN based on the RX VLAN acceleration setting.
Without this call to determine the default VLAN before calling
bnxt_setup_vnic(), the VNIC may not be set up correctly. For
example, bnxt_setup_vnic() may set up to strip the VLAN tag based
on stale default VLAN information. If RX VLAN acceleration is
not enabled, the VLAN tag will be incorrectly stripped and the
RX data path will not work correctly.

Only older NIC controller's firmware uses the PROC AP reset type.
Firmware on 5731X/5741X and newer chips does not support this reset
type. When bnxt_reset() issues a series of resets, this PROC AP
reset may actually fail on these newer chips because the firmware
is not ready to accept this unsupported command yet. Avoid this
unnecessary error by skipping this reset type on chips that don't
support it.

commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support") showed
improvements to power consumption over suspend when s0ix wasn't enabled in
BIOS and the system didn't support S3.
This patch however was misguided because the reason the system didn't
support S3 was because SMT was disabled in OEM BIOS setup.
This prevented the BIOS from allowing S3.
Also allowing GPUs to use the s2idle path actually causes problems if
they're invoked on systems that may not support s2idle in the platform
firmware. `systemd` has a tendency to try to use `s2idle` if `deep` fails
for any reason, which could lead to unexpected flows.
The original commit also fixed a problem during resume from suspend to idle
without hardware support, but this is no longer necessary with commit
ca4751866397 ("drm/amd: Don't allow s0ix on APUs older than Raven")

kafs incorrectly passes a zero mtime (ie. 1st Jan 1970) to the server when
creating a file, dir or symlink because the mtime recorded in the
afs_operation struct gets passed to the server by the marshalling routines,
but the afs_mkdir(), afs_create() and afs_symlink() functions don't set it.
This gets masked if a file or directory is subsequently modified.

The current ice driver's GNSS write implementation buffers writes and
works through them asynchronously in a kthread. That's bad because:
- The GNSS write_raw operation is supposed to be synchronous[1][2].
- There is no upper bound on the number of pending writes.
Userspace can submit writes much faster than the driver can process,
consuming unlimited amounts of kernel memory.
A patch that's currently on review[3] ("[v3,net] ice: Write all GNSS
buffers instead of first one") would add one more problem:
- The possibility of waiting for a very long time to flush the write
work when doing rmmod, softlockups.
To fix these issues, simplify the implementation: Drop the buffering,
the write_work, and make the writes synchronous.
I tested this with gpsd and ubxtool.

Commit 699b045a8e43 ("net: virtio_net: notifications coalescing
support") added coalescing command support for virtio_net. However,
the coalesce commands are using buffers on the stack, which is causing
the device to see DMA errors. There should also be a complaint from
check_for_stack() in debug_dma_map_xyz(). Fix this by adding and using
coalesce params from the control_buf struct, which aligns with other
commands.

Commit 523847df1b37 ("pds_core: add devcmd device interfaces") included
initial support for FW recovery detection. Unfortunately, the ordering
in pdsc_is_fw_good() was incorrect, which was causing FW recovery to be
undetected by the driver. Fix this by making sure to update the cached
fw_status by calling pdsc_is_fw_running() before setting the local FW
gen.

oldlen = (u16)~skb->len;
This part came with commit 0718bcc09b35 ("[NET]: Fix CHECKSUM_HW GSO problems.")
This leads to wrong TCP checksum.

A remote DoS vulnerability of RPL Source Routing is assigned CVE-2023-2156.
The Source Routing Header (SRH) has the following format:
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Next Header | Hdr Ext Len | Routing Type | Segments Left |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| CmprI | CmprE | Pad | Reserved |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| |
. .
. Addresses[1..n] .
. .
| |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
The originator of an SRH places the first hop's IPv6 address in the IPv6
header's IPv6 Destination Address and the second hop's IPv6 address as
the first address in Addresses[1..n].
The CmprI and CmprE fields indicate the number of prefix octets that are
shared with the IPv6 Destination Address. When CmprI or CmprE is not 0,
Addresses[1..n] are compressed as follows:
1..n-1 : (16 - CmprI) bytes
n : (16 - CmprE) bytes
Segments Left indicates the number of route segments remaining. When the
value is not zero, the SRH is forwarded to the next hop. Its address
is extracted from Addresses[n - Segment Left + 1] and swapped with IPv6
Destination Address.
When Segment Left is greater than or equal to 2, the size of SRH is not
changed because Addresses[1..n-1] are decompressed and recompressed with
CmprI.
OTOH, when Segment Left changes from 1 to 0, the new SRH could have a
different size because Addresses[1..n-1] are decompressed with CmprI and
recompressed with CmprE.
Let's say CmprI is 15 and CmprE is 0. When we receive SRH with Segment
Left >= 2, Addresses[1..n-1] have 1 byte for each, and Addresses[n] has
16 bytes. When Segment Left is 1, Addresses[1..n-1] is decompressed to
16 bytes and not recompressed. Finally, the new SRH will need more room
in the header, and the size is (16 - 1) * (n - 1) bytes.
Here the max value of n is 255 as Segment Left is u8, so in the worst case,
we have to allocate 3825 bytes in the skb headroom. However, now we only
allocate a small fixed buffer that is IPV6_RPL_SRH_WORST_SWAP_SIZE (16 + 7
bytes). If the decompressed size overflows the room, skb_push() hits BUG()
below [0].
Instead of allocating the fixed buffer for every packet, let's allocate
enough headroom only when we receive SRH with Segment Left 1.

The drm sched entity must be flushed before finishing, to account for
jobs potentially still in flight at that time.
Lima did not do this flush until now, so switch the destroy call to the
drm_sched_entity_destroy() wrapper which will take care of that.
This fixes a regression on lima which started since the rework in
commit 2fdb8a8f07c2 ("drm/scheduler: rework entity flush, kill and fini")
where some specific types of applications may hang indefinitely.
