The kerneldoc for usb_get_dev() and usb_get_intf() says that drivers
should always refcount the references they hold for the usb_device or
usb_interface structure, respectively. But this is an overstatement:
In many cases drivers do not access these references after they have
been unbound, and in such cases refcounting is unnecessary.
This patch updates the kerneldoc for the two routines, explaining when
a driver does not need to increment and decrement the refcount. This
should help dispel misconceptions which might otherwise afflict
programmers new to the USB subsystem.

Some Android x86 tablets with a Bay Trail (BYT) SoC and a Crystal Cove
PMIC, which does not support charger-detection, rely on the TUSB1211 phy
for charger-detection.
Windows tablets with the same SoC + PMIC often use an extra chip for
charger-detection like the FSA831A. But since on Android tablets
the designers already need to add a TUSB1211 phy to support device/gadget
mode the phy is used to do charger-detection instead.
These Android x86 tablets can be identified by the unique combination of
a Bay Trail SoC (already checked for by PCI-ids) + a Crystal Cove PMIC +
not using the standard ACPI battery and ac drivers. Where as on Windows
tablets the standard ACPI battery and ac drivers will be used on BYT
boards with a Crystal Cove PMIC.
Set a special kernel-internal (so not part of the dt-bindings)
"linux,phy_charger_detect" property on these boards, which tells the
tusb1210 driver to enable charger-detection.

Trying to disable Link Powermanagement (LPM) before port reset is
unnecessary and can cause additional delay if host can't communicate
with the device, which is often the reason why device is reset in the
first place.
usb_disable_lpm() will
- zero usb U1/U2 timeouts for the hub downstream port
- send ENABLE U1/U2 clear feature requests to the connected device.
- increase internal reference count for udev->lpm_disable_count
There is no need to zero U1/U2 hub port timeouts, or clearing the
U1/U2 enable for the connected device before reset. These are set
to default by the reset.
USB 3.1 section 10.2.2 "HUB Downstream port U1/U2 timers" states that:
"the U1 and U2 timeout values for a downstream port reset to the default
values when the port receives a SetPortFeature request for a port reset"
Set the udev->lpm_disable_count to "1" after port reset, which is the
default lpm_disable_count value when allocating udev, representing
disabled LPM.

Refactor xhci_dbc_init(), splitting it into logical
parts closer to the Linux device model.
- Create the fake dbc device, depends on xhci strucure
- Allocate a dbc structure, xhci agnostic
- Call xhci_dbc_tty_probe(), similar to actual probe.
Adjustments to xhci_dbc_exit and xhci_dbc_remove are also needed
as a result to the xhci_dbc_init() changes
Mostly non-functional changes, except for creating the dbc sysfs

This adds a debugfs file for ULPI devices which contains a dump of their
registers. This is useful for debugging basic connectivity problems. The
file is created in ulpi_register because many devices will never have a
driver bound (as they are managed in hardware by the USB controller
device).
The root directory of this subsystem is created before we register the
bus to ensure that devices can always create their directories.

Subsystems affected by this patch series: binfmt, procfs, and mm

kfence: make test case compatible with run time set sample interval

mm: vmscan: remove deadlock due to throttling failing to make progress
fs/proc: task_mmu.c: don't read mapcount for migration entry
fs/binfmt_elf: fix PT_LOAD p_align values for loaders
When the KCONFIG_AUTOCONFIG is specified (e.g. export \
KCONFIG_AUTOCONFIG=output/config/auto.conf), the directory of
include/config/ will not be created, so kconfig can't create deps
files in it and auto.conf can't be generated.

The parameter kfence_sample_interval can be set via boot parameter and
late shell command, which is convenient for automated tests and KFENCE
parameter optimization. However, KFENCE test case just uses
compile-time CONFIG_KFENCE_SAMPLE_INTERVAL, which will make KFENCE test
case not run as users desired. Export kfence_sample_interval, so that
KFENCE test case can use run-time-set sample interval.
