ps3_setup_uhc_device() is only called from ps3_setup_ehci_device() and
ps3_setup_ohci_device(), which are both marked __init. Hence replace
the former's __ref marker by __init.
Note that before commit bd721ea73e ("treewide: replace obsolete
_refok by __ref"), the function was marked __init_refok, which probably
should have been __init in the first place.

Christoffer reports that on some implementations, writing to
GICR_ISACTIVER0 (and similar GICD registers) can race badly with a guest
issuing a deactivation of that interrupt via the system register interface.
There are multiple reasons to this:
- this uses an early write-acknoledgement memory type (nGnRE), meaning
that the write may only have made it as far as some interconnect
by the time the store is considered "done"
- the GIC itself is allowed to buffer the write until it decides to
take it into account (as long as it is in finite time)
The effects are that the activation may not have taken effect by the time
the kernel enters the guest, forcing an immediate exit, or that a guest
deactivation occurs before the interrupt is active, doing nothing.
In order to guarantee that the write to the ISACTIVER register has taken
effect, read back from it, forcing the interconnect to propagate the write,
and the GIC to process the write before returning the read.

Some computers with CPUs that lack Thunderbolt features use discrete
Thunderbolt chips to add Thunderbolt functionality. These Thunderbolt
chips are located within the chassis; between the Root Port labeled
ExternalFacingPort and the USB-C port.
These Thunderbolt PCIe devices should be labeled as fixed and trusted, as
they are built into the computer. Otherwise, security policies that rely on
those flags may have unintended results, such as preventing USB-C ports
from enumerating.
Detect the above scenario through the process of elimination.
1) Integrated Thunderbolt host controllers already have Thunderbolt
implemented, so anything outside their external facing Root Port is
removable and untrusted.
Detect them using the following properties:
- Most integrated host controllers have the "usb4-host-interface"
ACPI property, as described here:
https://learn.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports#mapping-native-protocols-pcie-displayport-tunneled-through-usb4-to-usb4-host-routers
- Integrated Thunderbolt PCIe Root Ports before Alder Lake do not
have the "usb4-host-interface" ACPI property. Identify those by
their PCI IDs instead.
2) If a Root Port does not have integrated Thunderbolt capabilities, but
has the "ExternalFacingPort" ACPI property, that means the
manufacturer has opted to use a discrete Thunderbolt host controller
that is built into the computer.
This host controller can be identified by virtue of being located
directly below an external-facing Root Port that lacks integrated
Thunderbolt. Label it as trusted and fixed.
Everything downstream from it is untrusted and removable.
The "ExternalFacingPort" ACPI property is described here:
https://learn.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports#identifying-externally-exposed-pcie-root-ports

The suspend/resume functionality is currently broken on the i.MX6QDL
platform, as documented in the NXP errata (ERR005723):
https://www.nxp.com/docs/en/errata/IMX6DQCE.pdf
This patch addresses the issue by sharing most of the suspend/resume
sequences used by other i.MX devices, while avoiding modifications to
critical registers that disrupt the PCIe functionality. It targets the
same problem as the following downstream commit:
4e92355e1f
Unlike the downstream commit, this patch also resets the connected PCIe
device if possible. Without this reset, certain drivers, such as ath10k
or iwlwifi, will crash on resume. The device reset is also done by the
driver on other i.MX platforms, making this patch consistent with
existing practices.
Upon resuming, the kernel will hang and display an error. Here's an
example of the error encountered with the ath10k driver:
ath10k_pci 0000:01:00.0: Unable to change power state from D3hot to D0, device inaccessible
Unhandled fault: imprecise external abort (0x1406) at 0x0106f944
Without this patch, suspend/resume will fail on i.MX6QDL devices if a
PCIe device is connected.

Replacing `struct kcore_list *iter' with `struct kcore_list *tmp' doesn't change the

Currently, if __region_intersects() finds any overlapped but unmatched
resource, it walks the descendant resource tree to check for overlapped
and matched descendant resources using for_each_resource(). However, in
current kernel, for_each_resource() iterates not only the descendant tree,
but also subsequent sibling trees in certain scenarios. While this
doesn't introduce bugs, it makes code hard to be understood and
potentially inefficient.
So, the patch revises next_resource() and for_each_resource() and makes
for_each_resource() traverse the subtree under the specified subtree root
only. Test shows that this avoids unnecessary resource tree walking in
__region_intersects().
For the example resource tree as follows,
X
|
A----D----E
|
B--C
if 'A' is the overlapped but unmatched resource, original kernel
iterates 'B', 'C', 'D', 'E' when it walks the descendant tree. While
the patched kernel iterates only 'B', 'C'.
Thanks David Hildenbrand for providing a good resource tree example.

According to DA7212 HW manual, the codec's PLL input divider can operate
with MCLK range from 2MHz to 50MHz but current driver only set the
minimum supported MCLK frequency to 5MHz. That cause 11.025kHz audio
which is corresponding to MCLK of 2.8224MHz (11.025kHz * 256) unable to
play in case audio-simple-card is used.

On the Renesas RZ/G3S SMARC Carrier II board having a DA7212 codec (using
da7213 driver) connected to one SSIF-2 available on the Renesas RZ/G3S SoC
it has been discovered that using the runtime PM API for suspend/resume
(as will be proposed in the following commits) leads to the codec not
being propertly initialized after resume. This is because w/o
max_register populated to regmap_config the regcache_rbtree_sync()
breaks on base_reg > max condition and the regcache_sync_block() call is
skipped.

The SQ index array consists of user provided indexes, which io_uring
then uses to index the SQ, and so it's susceptible to speculation. For
all other queues io_uring tracks heads and tails in kernel, and they
shouldn't need any special care.

Rather than store the task_struct itself in struct io_kiocb, store
the io_uring specific task_struct. The life times are the same in terms
of io_uring, and this avoids doing some dereferences through the
task_struct. For the hot path of putting local task references, we can
deref req->tctx instead, which we'll need anyway in that function
regardless of whether it's local or remote references.
This is mostly straight forward, except the original task PF_EXITING
check needs a bit of tweaking. task_work is _always_ run from the
originating task, except in the fallback case, where it's run from a
kernel thread. Replace the potentially racy (in case of fallback work)
checks for req->task->flags with current->flags. It's either the still
the original task, in which case PF_EXITING will be sane, or it has
PF_KTHREAD set, in which case it's fallback work. Both cases should
prevent moving forward with the given request.

Currently the io_rsrc_node assignment in io_kiocb is an array of two
pointers, as two nodes may be assigned to a request - one file node,
and one buffer node. However, the buffer node can co-exist with the
provided buffers, as currently it's not supported to use both provided
and registered buffers at the same time.
This crucially brings struct io_kiocb down to 4 cache lines again, as
before it spilled into the 5th cacheline.

Rather than keep the type field separate rom ctx, use the fact that we
can encode up to 4 types of nodes in the LSB of the ctx pointer. Doesn't
reclaim any space right now on 64-bit archs, but it leaves a full int

arch_init_invariance_cppc() is called at the end of
acpi_cppc_processor_probe() in order to configure frequency invariance
based upon the values from _CPC.
This however doesn't work on AMD CPPC shared memory designs that have
AMD preferred cores enabled because _CPC needs to be analyzed from all
cores to judge if preferred cores are enabled.
This issue manifests to users as a warning since commit 21fb59ab4b
("ACPI: CPPC: Adjust debug messages in amd_set_max_freq_ratio() to warn"):
```
Could not retrieve highest performance (-19)
```
However the warning isn't the cause of this, it was actually
commit 279f838a61 ("x86/amd: Detect preferred cores in
amd_get_boost_ratio_numerator()") which exposed the issue.
To fix this problem, change arch_init_invariance_cppc() into a new weak
symbol that is called at the end of acpi_processor_driver_init().
Each architecture that supports it can declare the symbol to override
the weak one.
Define it for x86, in arch/x86/kernel/acpi/cppc.c, and for all of the
architectures using the generic arch_topology.c code.

GuC to host communication is interrupt driven, the handling has 3
parts: interrupt context, tasklet and request queue worker.
During GuC reset prepare, interrupt is disabled before destroy
contexts steps start. The IRQ and worker are flushed to finish
any outstanding in-progress message handling. But, the tasklet
flush is missing, it might causes 2 race conditions:
1. Tasklet runs after IRQ flushed, add request to queue after worker
flush started, causes unexpected G2H message request processing,
meanwhile, reset prepare code already get the context destroyed.
This will causes error reported about bad context state.
(https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/11349 and
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12303)
2. Tasklet runs after intel_guc_submission_reset_prepare,
ct_try_receive_message start to run, while intel_uc_reset_prepare
already finished guc sanitize and set ct->enable to false. This will
causes warning on incorrect ct->enable state.
(https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12439)
Add the missing tasklet flush to flush all 3 parts.
