"These revert a recent change in the schedutil cpufreq governor that
had not been expected to make any functional difference, but turned
out to introduce a performance regression, fix an initialization issue

- Fix amd-pstate driver initialization after running the kernel via

- Turn amd-pstate into a built-in driver which allows it to take

"There are a bunch of late fixes that just came in, in particular a
longer series for Rockchips devicetree files, but most of those just
address cosmetic errors that were found during the binding validation.
There are a couple of code changes:
- A regression fix to the IXP42x PCI bus
- A fix for a memory leak on optee, and another one for mach-mxs
- Two fixes for the sunxi rsb bus driver, to address problems with
the shutdown logic
The rest are small but important devicetree fixes for a number of
individual boards, addressing issues across all platforms:
- arm global timer on older rockchip SoCs is unstable and needs to be
disabled in favor of a more reliable clocksource
- Corrections to fix bluetooth, mmc, and networking on a few Rockchip
boards
- at91/sam9g20ek UDC needs a pin controller config change
- an omap board runs into mmc probe errors because of regulator nodes

The Hantro G2 video decoder block sits behind an IOMMU. The device tree
binding needs a property to reference it. Without a reference for the
implementation to properly configure the IOMMU, it will fault and cause
the video decoder to fail.
Add an "iommus" property for referring to the IOMMU port. The master ID
in the example is taken from the IOMMU fault error message on Linux,
and the number seems to match the order in the user manual's IOMMU
diagram.

"This is a pretty large diffstat for this time of the release. The main
culprit is a reorganization of the AMD assembly trampoline, allowing
percpu variables to be accessed early.
This is needed for the return stack depth tracking retbleed mitigation
that will be in 6.2, but it also makes it possible to tighten the IBRS
restore on vmexit. The latter change is a long tail of the
spectrev2/retbleed patches (the corresponding Intel change was simpler
and went in already last June), which is why I am including it right
now instead of sharing a topic branch with tip.
Being assembly and being rich in comments makes the line count balloon
a bit, but I am pretty confident in the change (famous last words)
because the reorganization actually makes everything simpler and more
understandable than before. It has also had external review and has
been tested on the aforementioned 6.2 changes, which explode quite
brutally without the fix.
Apart from this, things are pretty normal.

When a broken USB accessory connects to a USB host, usbcore might
keep doing enumeration retries. If the host has a watchdog mechanism,
the kernel panic will happen on the host.
This patch provides an attribute early_stop to limit the numbers of retries
for each port of a hub. If a port was marked with early_stop attribute,
unsuccessful connection attempts will fail quickly. In addition, if an
early_stop port has failed to initialize, it will ignore all future
connection events until early_stop attribute is clear.

When running under PV, the guest's TOD clock is under control of the
ultravisor and the hypervisor isn't allowed to change it. Hence, don't
allow userspace to change the guest's TOD clock by returning
-EOPNOTSUPP.
When userspace changes the guest's TOD clock, KVM updates its
kvm.arch.epoch field and, in addition, the epoch field in all state
descriptions of all VCPUs.
But, under PV, the ultravisor will ignore the epoch field in the state
description and simply overwrite it on next SIE exit with the actual
guest epoch. This leads to KVM having an incorrect view of the guest's
TOD clock: it has updated its internal kvm.arch.epoch field, but the
ultravisor ignores the field in the state description.
Whenever a guest is now waiting for a clock comparator, KVM will
incorrectly calculate the time when the guest should wake up, possibly
causing the guest to sleep for much longer than expected.
With this change, kvm_s390_set_tod() will now take the kvm->lock to be
able to call kvm_s390_pv_is_protected(). Since kvm_s390_set_tod_clock()
also takes kvm->lock, use __kvm_s390_set_tod_clock() instead.
The function kvm_s390_set_tod_clock is now unused, hence remove it.
Update the documentation to indicate the TOD clock attr calls can now
return -EOPNOTSUPP.

Commit 237405ebef ("arm64: cpufeature: Force HWCAP to be based on the
sysreg visible to user-space") forced the hwcaps to use sanitised
user-space view of the id registers. However, the ID register structures
used to select few compat cpufeatures (vfp, crc32, ...) are masked and
hence such hwcaps do not appear in /proc/cpuinfo anymore for PER_LINUX32
personality.
Add the ID register structures explicitly and set the relevant entry as
visible. As these ID registers are now of type visible so make them
available in 64-bit userspace by making necessary changes in register
emulation logic and documentation.
While at it, update the comment for structure ftr_generic_32bits[] which
lists the ID register that use it.
