Previous documentation suggested that PL1 power limit is always
enabled. However we now find this not to be the case on some
platforms (such as ATSM). Therefore enable PL1 power limit during hwmon
initialization.

On s390 PCI functions may be hotplugged individually even when they
belong to a multi-function device. In particular on an SR-IOV device VFs
may be removed and later re-added.
In commit a50297cf8235 ("s390/pci: separate zbus creation from
scanning") it was missed however that struct pci_bus and struct
zpci_bus's resource list retained a reference to the PCI functions MMIO
resources even though those resources are released and freed on
hot-unplug. These stale resources may subsequently be claimed when the
PCI function re-appears resulting in use-after-free.
One idea of fixing this use-after-free in s390 specific code that was
investigated was to simply keep resources around from the moment a PCI
function first appeared until the whole virtual PCI bus created for
a multi-function device disappears. The problem with this however is
that due to the requirement of artificial MMIO addreesses (address
cookies) extra logic is then needed to keep the address cookies
compatible on re-plug. At the same time the MMIO resources semantically
belong to the PCI function so tying their lifecycle to the function
seems more logical.
Instead a simpler approach is to remove the resources of an individually
hot-unplugged PCI function from the PCI bus's resource list while
keeping the resources of other PCI functions on the PCI bus untouched.
This is done by introducing pci_bus_remove_resource() to remove an
individual resource. Similarly the resource also needs to be removed
from the struct zpci_bus's resource list. It turns out however, that
there is really no need to add the MMIO resources to the struct
zpci_bus's resource list at all and instead we can simply use the
zpci_bar_struct's resource pointer directly.

Starting from an used_idx different than 0 is needed in use cases like
virtual machine migration. Not doing so and letting the caller set an
avail idx different than 0 causes destination device to try to use old
buffers that source driver already recover and are not available
anymore.
Since vdpa_sim does not support receive inflight descriptors as a
destination of a migration, let's set both avail_idx and used_idx the
same at vq start. This is how vhost-user works in a
VHOST_SET_VRING_BASE call.
Although the simple fix is to set last_used_idx at vdpasim_set_vq_state,
it would be reset at vdpasim_queue_ready. The last_avail_idx case is
fixed with commit 0e84f918fac8 ("vdpa_sim: not reset state in
vdpasim_queue_ready"). Since the only option is to make it equal to
last_avail_idx, adding the only change needed here.
This was discovered and tested live migrating the vdpa_sim_net device.

Currently vhost_vdpa_cleanup() unmaps the DMA mappings by calling
`iommu_unmap(v->domain, map->start, map->size);`
from vhost_vdpa_general_unmap() when the parent vDPA driver doesn't
provide DMA config operations.
However, the IOMMU domain referred to by `v->domain` is freed in
vhost_vdpa_free_domain() before vhost_vdpa_cleanup() in
vhost_vdpa_release() which results in NULL pointer de-reference.
Accordingly, moving the call to vhost_vdpa_free_domain() in
vhost_vdpa_cleanup() would makes sense. This will also help
detaching the dma device in error handling of vhost_vdpa_alloc_domain().
This issue was observed on terminating QEMU with SIGQUIT.

AMD has issued an advisory indicating that having fTPM enabled in
BIOS can cause "stuttering" in the OS. This issue has been fixed
in newer versions of the fTPM firmware, but it's up to system
designers to decide whether to distribute it.
This issue has existed for a while, but is more prevalent starting
with kernel 6.1 because commit b006c439d58db ("hwrng: core - start
hwrng kthread also for untrusted sources") started to use the fTPM
for hwrng by default. However, all uses of /dev/hwrng result in
unacceptable stuttering.
So, simply disable registration of the defective hwrng when detecting
these faulty fTPM versions. As this is caused by faulty firmware, it
is plausible that such a problem could also be reproduced by other TPM
interactions, but this hasn't been shown by any user's testing or reports.
It is hypothesized to be triggered more frequently by the use of the RNG
because userspace software will fetch random numbers regularly.
Intentionally continue to register other TPM functionality so that users
that rely upon PCR measurements or any storage of data will still have
access to it. If it's found later that another TPM functionality is
exacerbating this problem a module parameter it can be turned off entirely
and a module parameter can be introduced to allow users who rely upon
fTPM functionality to turn it on even though this problem is present.

tpm_read_log_acpi() should return -ENODEV when no eventlog from the ACPI
table is found. If the firmware vendor includes an invalid log address
we are unable to map from the ACPI memory and tpm_read_log() returns -EIO
which would abort discovery of the eventlog.
Change the return value from -EIO to -ENODEV when acpi_os_map_iomem()
fails to map the event log.

When probing the ucd90320 access to some of the registers randomly fails.
Sometimes it NACKs a transfer, sometimes it returns just random data and
the PEC check fails.
Experimentation shows that this seems to be triggered by a register access
directly back to back with a previous register write. Experimentation also
shows that inserting a small delay after register writes makes the issue go
away.
Use a similar solution to what the max15301 driver does to solve the same
problem. Create a custom set of bus read and write functions that make sure
that the delay is added.

- rtl8723bs driver fixes for issues found by Hans in testing
The deleted driver is the removal of the r8188eu wireless driver as
now in 6.3-rc1 we have a "real" wifi driver for one that includes
support for many many more devices than this old driver did. So it's
time to remove it as it is no longer needed. The maintainers of this
driver all have acked its removal. Many thanks to them over the years
for working to clean it up and keep it working while the real driver
was being developed.

Even though we are passing 'ret' as stop condition for
read_poll_timeout(), that return code is still being ignored. The reason
is that the poll will stop if the passed condition is true which will
happen if the passed op() returns error. However, read_poll_timeout()
returns 0 if the *complete* condition evaluates to true. Therefore, the
error code returned by op() will be ignored.
To fix this we need to check for both error codes:
* The one returned by read_poll_timeout() which is either 0 or
ETIMEDOUT.
* The one returned by the passed op().

For l3s mode, skb->dev is set to ipvlan interface in ipvlan_nf_input():
skb->dev = addr->master->dev
but, skb->skb_iif remain unchanged, this will cause socket lookup failed
if a target socket is bound to a interface, like the following example:
ip link add ipvlan0 link eth0 type ipvlan mode l3s
ip addr add dev ipvlan0 192.168.124.111/24
ip link set ipvlan0 up
ping -c 1 -I ipvlan0 8.8.8.8
100% packet loss
This is because there is no match sk in __raw_v4_lookup() as sk->sk_bound_dev_if != dif(skb->skb_iif).
Fix this by make skb->skb_iif track skb->dev in ipvlan_nf_input().

The recent fix for the deferred I/O by the commit
3efc61d95259 ("fbdev: Fix invalid page access after closing deferred I/O devices")
caused a regression when the same fb device is opened/closed while
it's being used. It resulted in a frozen screen even if something
is redrawn there after the close. The breakage is because the patch
was made under a wrong assumption of a single open; in the current
code, fb_deferred_io_release() cleans up the page mapping of the
pageref list and it calls cancel_delayed_work_sync() unconditionally,
where both are no correct behavior for multiple opens.
This patch adds a refcount for the opens of the device, and applies
the cleanup only when all files get closed.
As both fb_deferred_io_open() and _close() are called always in the
fb_info lock (mutex), it's safe to use the normal int for the
refcounting.
Also, a useless BUG_ON() is dropped.

Prior to commit 5d8e6e6c10a3 ("nvmem: core: add an index parameter to
the cell") of_nvmem_cell_get() would return -ENOENT if the cell wasn't
found. Particularly, if of_property_match_string() returned -EINVAL,
that return code was passed as the index to of_parse_phandle(), which
then detected it as invalid and returned NULL. That led to an return
code of -ENOENT.
With the new code, the negative index will lead to an -EINVAL of
of_parse_phandle_with_optional_args() which pass straight to the
caller and break those who expect an -ENOENT.
Fix it by always returning -ENOENT.

Actually, the drm_dev_enter in psp_cmd_submit_buf does not
protect anything. If DRM device is unplugged, it will always
check the condition in WARN_ON. So drop drm_dev_enter and
drm_dev_exit in psp_cmd_submit_buf.
When removing amdgpu, the calling order is as follows:
amdgpu_pci_remove
drm_dev_unplug
amdgpu_driver_unload_kms
amdgpu_device_fini_hw
amdgpu_device_ip_fini_early
psp_hw_fini
psp_ras_terminate
psp_ta_unloadye
psp_cmd_submit_buf

This patch fixes a return value check in kfd doorbell handling.
This function should return 0(error) only when the ida_simple_get
returns < 0(error), return > 0 is a success case.

The same strapping initialization issue that happened on NBIO 7.5.1
appears to be happening on NBIO 7.3.0.
Apply the same fix to 7.3.0 as well.
Note: This workaround relies upon the integrated GPU being enabled
in BIOS. If the integrated GPU is disabled in BIOS a different
workaround will be required.

On GPUs with RAS enabled, below call trace and hang are observed when
shutting down device.
v2: use DRM device unplugged flag instead of shutdown flag as the check to
prevent memory wipe in shutdown stage.

Multi Circular Queue doesn't use outstanding_reqs. However, the UFS clock
scaling functions use outstanding_reqs to determine if there are requests
pending. When MCQ is enabled, this check always returns false.
Hence use active_reqs to check if there are pending requests.
