When using dm-verity with a data partition on an emmc device, dm-verity

Looking closely it's obvious that only the 32-bit part of the address
(0xfffff200) arrives at the SMMU, the higher 16-bit (0xffff...) get
lost somewhere. This might not be a limitation of the SDHCI itself but
perhaps the bus/interconnect it is connected to, or even the connection
to the SMMU.
Work around this by setting SDHCI_QUIRK2_BROKEN_64_BIT_DMA to avoid
using 64-bit addresses.

Bayhub SD host has hardware limitation:

SD Host Register [03E][13]=1 (64bits addressing) mode.
2.Because of above item#1, need to configure SD Host Register [03E][13] to
1(64bits addressing mode) before set 64bit ADMA system address's higher
32bits SD Host Register [05F~05C] if 64 bits addressing mode is used.
The hardware limitation is reasonable for below reasons:
1.Normal flow should set DMA working mode first, then do
DMA-transfer-related configuration, such as system address.
2.The hardware limitation may avoid the software to configure wrong higher
32bit address at 32bits addressing mode although it is redundant.
The change that set 32bits/64bits addressing mode before set ADMA address,
has no side-effect to other host IPs for below reason:
The setting order is reasonable and standard: DMA Mode setting first and

11240000.mmc: error -ENXIO: IRQ sdio_wakeup not found
It's pretty normal not to have an "sdio_wakeup" IRQ defined. In fact,
no device trees in mainline seem to have it. Let's use the
platform_get_irq_byname_optional() to avoid the error message.

mmc: meson-mx-sdhc: Avoid cast to incompatible function type
Rather than casting mmc_free_host to an incompatible function type,

The same approach is taken in litex_mmc.c with the function

Convert the drivers that use this function as .remove() callback to
.remove_new() which has the right prototype. This helps getting rid of
the platform_driver's remove callback that returns an int (which is

drm/msm/dp: enable HDP plugin/unplugged interrupts at hpd_enable/disable
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()

vhost: Fix worker hangs due to missed wake up calls
We can race where we have added work to the work_list, but
vhost_task_fn has passed that check but not yet set us into
TASK_INTERRUPTIBLE. wake_up_process will see us in TASK_RUNNING and
just return.
This bug was intoduced in commit
f9010dbdce91 ("fork, vhost: Use
CLONE_THREAD to fix freezer/ps regression") when I moved the setting
of TASK_INTERRUPTIBLE to simplfy the code and avoid get_signal from
logging warnings about being in the wrong state. This moves the setting
of TASK_INTERRUPTIBLE back to before we test if we need to stop the
task to avoid a possible race there as well. We then have vhost_worker
set TASK_RUNNING if it finds work similar to before.

vhost: Fix crash during early vhost_transport_send_pkt calls
If userspace does VHOST_VSOCK_SET_GUEST_CID before VHOST_SET_OWNER we
can race where:
1. thread0 calls vhost_transport_send_pkt -> vhost_work_queue
2. thread1 does VHOST_SET_OWNER which calls vhost_worker_create.
3. vhost_worker_create will set the dev->worker pointer before setting
the worker->vtsk pointer.
4. thread0's vhost_work_queue will see the dev->worker pointer is
set and try to call vhost_task_wake using not yet set worker->vtsk
pointer.
5. We then crash since vtsk is NULL.
Before commit
6e890c5d5021 ("vhost: use vhost_tasks for worker
threads"), we only had the worker pointer so we could just check it to
see if VHOST_SET_OWNER has been done. After that commit we have the
vhost_worker and vhost_task pointer, so we can now hit the bug above.
This patch embeds the vhost_worker in the vhost_dev and moves the work
list initialization back to vhost_dev_init, so we can just check the
worker.vtsk pointer to check if VHOST_SET_OWNER has been done like
before.

The fix is to disable and destroy the workqueue after the device
unregister. It is expected that vhost will not trigger kicks after
the unregister. But even if it would, the wq is disabled already by
setting the pointer to NULL (done so in the referenced commit).

ext4: only check dquot_initialize_needed() when debugging
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

bnxt_en: Implement .set_port / .unset_port UDP tunnel callbacks
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.

bnxt_en: Query default VLAN before VNIC setup on a VF
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.

bnxt_en: Don't issue AP reset during ethtool's reset operation
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.
