So far it was necessary for usb functions to set ep->driver_data in
endpoint obtained from autoconfig to non-null value, to indicate that
endpoint is claimed by function (in autoconfig it was checked if endpoint
has set this field to non-null value, and if it has, it was assumed that
it is claimed). It could cause bugs because if some function doesn't
set this field autoconfig could return the same endpoint more than one
time.
To help to avoid such bugs this patch adds claimed flag to struct usb_ep,
and encapsulates endpoint claiming mechanism inside usb_ep_autoconfig_ss()
and usb_ep_autoconfig_reset(), so now usb functions don't need to perform
any additional actions to mark endpoint obtained from autoconfig as claimed.

xen/gntdevt: Fix race condition in gntdev_release()
An event channel bound to a CPU that was offlined may still be linked
on that CPU's queue. If this event channel is closed and reused,
subsequent events will be lost because the event channel is never
unlinked and thus cannot be linked onto the correct queue.
When a channel is closed and the event is still linked into a queue,
ensure that it is unlinked before completing.
If the CPU to which the event channel bound is online, spin until the
event is handled by that CPU. If that CPU is offline, it can't handle
the event, so clear the event queue during the close, dropping the
events.
This fixes the missing interrupts (and subsequent disk stalls etc.)
when offlining a CPU.

During unbinding the driver was dereferencing a pointer to memory
already freed by power_supply_unregister().
Driver was freeing its internal description of battery through pointers
stored in power_supply structure. However, because the core owns the
power supply instance, after calling power_supply_unregister() this
memory is freed and the driver cannot access these members.
Fix this by storing the pointer to internal description of battery in a
local variable before calling power_supply_unregister(), so the pointer
remains valid.

WACOM_QUIRK_NO_INPUT is a signal to the driver that input devices
should not be created for a particular device. This quirk was used by
the wireless receiver to prevent any devices from being created during
the initial probe (defering it instead until we got a tablet connection
event in 'wacom_wireless_work').
This quirk is not necessary now that a device_type is associated with each
device. Any input device allocated by 'wacom_allocate_inputs' which is
not necessary for a particular device is freed in 'wacom_register_inputs'.
In particular, none of the wireless receivers devices have the pen, pad,
or touch device types set so the same effect is achieved without the need
to be explicit.
We now return early in wacom_retrieve_hid_descriptor for wireless devices
(to prevent the device_type from being overridden) but since we ignore the
HID descriptor for the wireless reciever anyway, this is not an issue.

Commit 3228950621 ("irqchip: gic: Preserve gic V2 bypass bits in cpu
ctrl register") added a new function, gic_cpu_if_up(), to program the
GIC CPU_CTRL register. This function assumes that there is only one GIC
instance present and hence always uses the chip data for the primary GIC
controller. Although it is not common for there to be a secondary, some
devices do support a secondary. Therefore, fix this by passing
gic_cpu_if_up() a pointer to the appropriate chip data structure.
Similarly, the function gic_cpu_if_down() only assumes that there is a
single GIC instance present. Update this function so that an instance
number is passed for the appropriate GIC and return an error code on
failure. The vexpress TC2 (which has a single GIC) is currently the only
user of this function and so update it accordingly. Note that because the
TC2 only has a single GIC, the call to gic_cpu_if_down() should always
be successful.

The gic_init_bases() function initialises an array that stores the mapping
between the GIC and CPUs. This array is a global array that is
unconditionally initialised on every call to gic_init_bases(). Although,
it is not common for there to be more than one GIC instance, there are
some devices that do support nested GIC controllers and gic_init_bases()
can be called more than once.
A 2nd call to gic_init_bases() will clear the previous CPU mapping and
will only setup the mapping again for the CPU calling gic_init_bases().
Fix this by only allowing the CPU map to be configured for the primary GIC.
For secondary GICs the CPU map is not relevant because these GICs do not
directly route the interrupts to the main CPU(s) but to other GICs or
devices.

NUMA emulation (aka fake NUMA) distributes the available memory to nodes
without using real topology information about the physical memory of the
machine.
Splitting the system memory into nodes replicates the memory management
structures for each node. Particularly each node has its own "mm locks"
and its own "kswapd" task.
For large systems, under certain conditions, this results in improved
system performance and/or latency based on reduced pressure on the mm
locks and the kswapd tasks.
NUMA emulation distributes CPUs to nodes while respecting the original
machine topology information. This is done by trying to avoid to separate
CPUs which reside on the same book or even on the same MC. Because the
current Linux scheduler code requires a stable cpu to node mapping, cores
are pinned to nodes when the first CPU thread is set online.
This patch is based on the initial implementation from Philipp Hachtmann.
