The firmware of R-Car USB 3.0 host controller will control the reset.
So, if the xhci driver doesn't do firmware downloading (e.g. kernel
configuration is CONFIG_USB_XHCI_PLATFORM=y and CONFIG_USB_XHCI_RCAR
is not set), the reset of USB 3.0 host controller doesn't work
correctly. Then, the host controller will cause long wait in
xhci_reset() because the CMD_RESET bit of op_regs->command is not
cleared for 10 seconds.
So, this patch modifies the Kconfig to enable both CONFIG_USB_XHCI_PLATFORM
and CONFIG_USB_XHCI_RCAR.
Fixes: 4ac8918f3a7 (usb: host: xhci-plat: add support for the R-Car H2 and M2 xHCI controllers)

sti-cpufreq, ARM64 cpuidle, Operating Performance Points framework,
generic device properties framework) and one fix for a hotplug-related
deadlock in ACPICA that's been there forever, but is nasty enough.
Specifics:
- Fix for a recent regression in the intel_pstate driver causing it
to fail to restore the HWP (HW-managed P-states) configuration of
the boot CPU after suspend-to-RAM (Rafael Wysocki).
- Fix for two recent regressions in the intel_pstate driver, one that
can trigger a divide by zero if the driver is accessed via sysfs
before it manages to take the first sample and one causing it to
fail to update a structure field used in a trace point, so the
information coming from it is less useful (Rafael Wysocki).
- Fix for a problem in the sti-cpufreq driver introduced during the
4.5 cycle that causes it to break CPU PM in multi-platform kernels
by registering cpufreq-dt (which subsequently doesn't work)
unconditionally and preventing the driver that would actually work
from registering (Sudeep Holla).
- Stable-candidate fix for an ARM64 cpuidle issue causing idle state
usage counters to be incorrectly updated for idle states that were
not entered due to errors (James Morse).
- Fix for a recently introduced issue in the OPP (Operating
Performance Points) framework causing it to print bogus error
messages for missing optional regulators (Viresh Kumar).
- Fix for a recently introduced issue in the generic device

Pull libnvdimm fixes from Dan Williams:
- a fix for the persistent memory 'struct page' driver. The
implementation overlooked the fact that pages are allocated in 2MB
units leading to -ENOMEM when establishing some configurations.
It's tagged for -stable as the problem was introduced with the
initial implementation in 4.5.
- The new "error status translation" routine, introduced with the 4.6
updates to the nfit driver, missed a necessary path in
acpi_nfit_ctl().
The end result is that we are falsely assuming commands complete
successfully when the embedded status says otherwise.

iSER currently has a couple places that set max_sectors in either the host
template or SCSI host, and all of them get it wrong.
This patch instead uses a single assignment that (hopefully) gets it right:
the max_sectors value must be derived from the number of segments in the
FR or FMR structure, but actually be one lower than the page size multiplied
by the number of sectors, as it has to handle the case of non-aligned I/O.
Without this I get trivial to reproduce hangs when running xfstests
(on XFS) over iSER to Linux targets.

The copying of ring data was wrong for two cases: For a full ring
nothing got copied at all (as in that case the canonicalized producer
and consumer indexes are identical). And in case one or both of the
canonicalized (after the resize) indexes would point into the second
half of the buffer, the copied data ended up in the wrong (free) part
of the new buffer. In both cases uninitialized data would get passed
back to the caller.
Fix this by simply copying the old ring contents twice: Once to the
low half of the new buffer, and a second time to the high half.
This addresses the inability to boot a HVM guest with 64 or more
vCPUs. This regression was caused by 8620015499101090 (xen/evtchn:
dynamically grow pending event channel ring).

After commit 8fa520af5081 "intel_pstate: Remove freq calculation from
intel_pstate_calc_busy()" intel_pstate_get() calls get_avg_frequency()
to compute the average frequency, which is problematic for two reasons.
First, intel_pstate_get() may be invoked before the driver reads the
CPU feedback registers for the first time and if that happens,
get_avg_frequency() will attempt to divide by zero.
Second, the get_avg_frequency() call in intel_pstate_get() is racy
with respect to intel_pstate_sample() and it may end up returning
completely meaningless values for this reason.
Moreover, after commit 7349ec0470b6 "intel_pstate: Move
intel_pstate_calc_busy() into get_target_pstate_use_performance()"
sample.core_pct_busy is never computed on Atom, but it is used in
intel_pstate_adjust_busy_pstate() in that case too.
To address those problems notice that if sample.core_pct_busy
was used in the average frequency computation carried out by
get_avg_frequency(), both the divide by zero problem and the
race with respect to intel_pstate_sample() would be avoided.
Accordingly, move the invocation of intel_pstate_calc_busy() from
get_target_pstate_use_performance() to intel_pstate_update_util(),
which also will take care of the uninitialized sample.core_pct_busy
on Atom, and modify get_avg_frequency() to use sample.core_pct_busy
as per the above.

Fix this by calculating the pattern byte based on total sent size
instead of just the current sg entry.

The return type of usbhsp_setup_pipecfg() was u16 but it was returning
a negative value (-EINVAL). Lets have an additional argument which will
have pipecfg and just return the status (success or error) as the return
from the function.

When a USB driver is bound to an interface (either through probing or
by claiming it) or is unbound from an interface, the USB core always
disables Link Power Management during the transition and then
re-enables it afterward. The reason is because the driver might want
to prevent hub-initiated link power transitions, in which case the HCD
would have to recalculate the various LPM parameters. This
recalculation takes place when LPM is re-enabled and the new
parameters are sent to the device and its parent hub.
However, if the driver does not want to prevent hub-initiated link
power transitions then none of this work is necessary. The parameters
don't need to be recalculated, and LPM doesn't need to be disabled and
re-enabled.
It turns out that disabling and enabling LPM can be time-consuming,
enough so that it interferes with user programs that want to claim and
release interfaces rapidly via usbfs. Since the usbfs kernel driver
doesn't set the disable_hub_initiated_lpm flag, we can speed things up
and get the user programs to work by leaving LPM alone whenever the
flag isn't set.
And while we're improving the way disable_hub_initiated_lpm gets used,
let's also fix its kerneldoc.

The current sequence makes us register for a network device prior to
registering and probing the MDIO bus which could lead to some unwanted
consequences, like a thread of execution calling into ndo_open before
register_netdev() returns, while the MDIO bus is not ready yet.
Rework the sequence to register for the MDIO bus, and therefore attach
to a PHY prior to calling register_netdev(), which implies reworking the
error path a bit.

Since commit 3b9d6da67e11 ("cpu/hotplug: Fix rollback during error-out
in __cpu_disable()") it is ensured that callbacks of CPU_ONLINE and
CPU_DOWN_PREPARE are processed on the hotplugged CPU. Due to this SMP
function calls are no longer required.
Replace smp_call_function_single() with a direct call to
mvneta_percpu_enable() or mvneta_percpu_disable(). The functions do
not require to be called with interrupts disabled, therefore the
smp_call_function_single() calling convention is not preserved.

Now mdiobus_scan() returns ERR_PTR(-ENODEV) instead of NULL if the PHY
device ID was read as all ones. As this was not an error before, this
value should be filtered out now in this driver.

Since mdiobus_scan() returns either an error code or NULL on error, the
driver should check for both, not only for NULL, otherwise a crash is
imminent...
