Robert Hancock says:
====================
Allow disabling KSZ switch refclock
The reference clock output from the KSZ9477 and related Microchip
switch devices is not required on all board designs. Add a device
tree property to disable it for power and EMI reasons.
Changes since v3:
-rework some code for simplicity
Changes since v2:
-check for conflicting options in DT, added note in bindings doc
Changes since v1:
-added Acked-by on patch 1, rebase to net-next

When the consumer works, it should enable the smi-larb's power which
also need enable the smi-common's power firstly.
Thus, First of all, use the device link connect the consumer and the
smi-larbs. then add device link between the smi-larb and smi-common.
This patch adds device_link between the consumer and the larbs.
When device_link_add, I add the flag DL_FLAG_STATELESS to avoid calling
pm_runtime_xx to keep the original status of clocks. It can avoid two
issues:
1) Display HW show fastlogo abnormally reported in [1]. At the beggining,
all the clocks are enabled before entering kernel, but the clocks for
display HW(always in larb0) will be gated after clk_enable and clk_disable
called from device_link_add(->pm_runtime_resume) and rpm_idle. The clock
operation happened before display driver probe. At that time, the display
HW will be abnormal.
2) A deadlock issue reported in [2]. Use DL_FLAG_STATELESS to skip
pm_runtime_xx to avoid the deadlock.
Corresponding, DL_FLAG_AUTOREMOVE_CONSUMER can't be added, then
device_link_removed should be added explicitly.
Meanwhile, Currently we don't have a device connect with 2 larbs at the
same time. Disallow this case, print the error log.

Prepare for adding device_link.
The iommu consumer should use device_link to connect with the
smi-larb(supplier). then the smi-larb should run before the iommu
consumer. Here we delay the iommu driver until the smi driver is ready,
then all the iommu consumers always are after the smi driver.
When there is no this patch, if some consumer drivers run before
smi-larb, the supplier link_status is DL_DEV_NO_DRIVER(0) in the
device_link_add, then device_links_driver_bound will use WARN_ON
to complain that the link_status of supplier is not right.

When the iommu master device enters of_iommu_xlate, the ops may be
NULL(iommu dev is defered), then it will initialize the fwspec here:

[<c06c0d38>] (of_iommu_xlate) from [<c06c10e8>]
(of_iommu_configure+0x144/0x1e8)
BUT the mtk_iommu_v1.c only supports arm32, the probing flow still is a bit
weird. We always expect create the fwspec internally. otherwise it will
enter here and return fail.
static int mtk_iommu_create_mapping(struct device *dev,
struct of_phandle_args *args)
{
...
if (!fwspec) {
....
} else if (dev_iommu_fwspec_get(dev)->ops != &mtk_iommu_ops) {
>>>>>>>>>>Enter here. return fail.<<<<<<<<<<<<
return -EINVAL;
}
...
}
Thus, Free the existed fwspec if the master device already has fwspec.

Hyper-V TLFS explicitly forbids VMREAD and VMWRITE instructions when
Enlightened VMCS interface is in use:
"Any VMREAD or VMWRITE instructions while an enlightened VMCS is
active is unsupported and can result in unexpected behavior.""
Windows 11 + WSL2 seems to ignore this, attempts to VMREAD VMCS field
0x4404 ("VM-exit interruption information") are observed. Failing
these attempts with nested_vmx_failInvalid() makes such guests
unbootable.
Microsoft confirms this is a Hyper-V bug and claims that it'll get fixed
eventually but for the time being we need a workaround. (Temporary) allow
VMREAD to get data from the currently loaded Enlightened VMCS.
Note: VMWRITE instructions remain forbidden, it is not clear how to
handle them properly and hopefully won't ever be needed.

In preparation to allowing reads from Enlightened VMCS from
handle_vmread(), implement evmcs_field_offset() to get the correct
read offset. get_evmcs_offset(), which is being used by KVM-on-Hyper-V,
is almost what's needed but a few things need to be adjusted. First,
WARN_ON() is unacceptable for handle_vmread() as any field can (in
theory) be supplied by the guest and not all fields are defined in
eVMCS v1. Second, we need to handle 'holes' in eVMCS (missing fields).
It also sounds like a good idea to WARN_ON() if such fields are ever
accessed by KVM-on-Hyper-V.

Similar to MSR_IA32_VMX_EXIT_CTLS/MSR_IA32_VMX_TRUE_EXIT_CTLS,
MSR_IA32_VMX_ENTRY_CTLS/MSR_IA32_VMX_TRUE_ENTRY_CTLS pair,
MSR_IA32_VMX_TRUE_PINBASED_CTLS needs to be filtered the same way
MSR_IA32_VMX_PINBASED_CTLS is currently filtered as guests may solely rely
on 'true' MSR data.
Note, none of the currently existing Windows/Hyper-V versions are known
to stumble upon the unfiltered MSR_IA32_VMX_TRUE_PINBASED_CTLS, the change
is aimed at making the filtering future proof.

For the NL80211_REGDOM_SET_BY_USER hint from cfg80211, it set the new
alpha2 code to ath11k, then ath11k send WMI_SET_INIT_COUNTRY_CMDID to
firmware for all chips currently. When test with WCN6855/QCA6390 chips,
this WMI CMD leads firmware crash.
For AP based chips(ipq8074/qcn9074), WMI_SET_INIT_COUNTRY_CMDID is used
to send to firmware, for STATION based chips(WCN6855/QCA6390), it need to
use another WMI CMD WMI_SET_CURRENT_COUNTRY_CMDID.
Add flag current_cc_support in hardware parameters, it is used to
distinguish AP/STA platform. After that, the firmware will work
normal and the regulatory feature works well for QCA6390/WCN6855.

When station connect to AP of 6 GHz with 40 MHz bandwidth, the TX is
always stay 20 MHz, it is because the flag WMI_PEER_40MHZ is not set
while peer assoc. Add the flag if remote peer is 40 MHz bandwidth.

Because KVM_GET_SUPPORTED_CPUID is meant to be passed (by simple-minded
VMMs) to KVM_SET_CPUID2, it cannot include any dynamic xsave states that
have not been enabled. Probing those, for example so that they can be
passed to ARCH_REQ_XCOMP_GUEST_PERM, requires a new ioctl or arch_prctl.
The latter is in fact worse, even though that is what the rest of the
API uses, because it would require supported_xcr0 to be moved from the
KVM module to the kernel just for this use. In addition, the value
would be nonsensical (or an error would have to be returned) until
the KVM module is loaded in.
Therefore, to limit the growth of system ioctls, add a /dev/kvm
variant of KVM_{GET,HAS}_DEVICE_ATTR, and implement it in x86
with just one group (0) and attribute (KVM_X86_XCOMP_GUEST_SUPP).

After adding device_link between the consumer with the smi-larbs,
if the consumer call its owner pm_runtime_get(_sync), the
pm_runtime_get(_sync) of smi-larb and smi-common will be called
automatically. Thus, the consumer don't need this property.
And IOMMU also know which larb this consumer connects with from
iommu id in the "iommus=" property.

Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing
field initialization.
In htc_connect_service() svc_meta_len and pad are not initialized. Based
on code it looks like in current skb there is no service data, so simply
initialize svc_meta_len to 0.
htc_issue_send() does not initialize htc_frame_hdr::control array. Based
on firmware code, it will initialize it by itself, so simply zero whole
array to make KMSAN happy

The quantization tables used in the Hantro JPEG encoder driver are
implicitly sized by the data they contain, but the loop that scales
the tables based on the compression quality hard codes the size to
64. No code exists to check whether the two actually match.
Commit 85bdcb7eaa ("media: hantro: Write the quantization tables in
proper order") introduced two new tables, with sizes hardcoded to 64,
but still no checking if all the sizes are the same.
Commit 41479adb5e ("media: hantro: Avoid global variable for jpeg
quantization tables") added the macro JPEG_QUANT_SIZE, but only the
newly added fields used this.
This has resulted in code scattered with magic numbers and array sizes
that happen to match up, without any sort of sanity checking to enforce
it.
Drop the hard-coded array sizes, replace the magic loop count with
a proper JPEG_QUANT_SIZE macro, and add BUILD_BUG_ON()s to check
that all the table sizes match up.

the JPEG encoder can output to the capture buffers directly without
going through a bounce buffer.
Do just that, and get rid of all the bounce buffer related code.

Remove some unneeded wrapping around the detection functions, and

The Hantro JPEG encoder driver adds various segments to the JPEG header.
While it would be quite complicated to make these segments selectable
to userspace, given that the driver has to fill in various fields in
these segments, and also take care of alignment, it would be nice if
the driver could signal to userspace what segments are included.
Implement the V4L2_CID_JPEG_ACTIVE_MARKER control, and make it read
only so that it always returns the set of segments that the driver adds.
