To build an EP driver which is based on PCIe designware as module, we
need to get some symbols from pcie-designware_ep.c. To select the
source from GKI kernel, we should enable PCIE_DW_PLAT_EP driver as
prebuilt.

Send uevent when received control request 51 and 52
to help debug and recover when the handshake not finished.
Description about control request 51 and 52
control_request 51 :
Send a 51 control request ("Get Protocol") to figure out
if the device supports the Android accessory protocol.
A non-zero number is returned if the protocol is supported,
which represents the version of the protocol that
the device supports (currently, only version 1 exists).
control_request 52 :
If the device returns a proper protocol version,
send identifying string information to the device.
This information allows the device to figure out
an appropriate application for this accessory and
also present the user with a URL if
an appropriate application does not exist.
The detail description could reference below link.

When submitting a cherry-picked version of commit c700bdd223
("ANDROID: dma-heap: Add proper kref handling on dma-buf heaps")
from the android-mainline tree, Greg had some feedback that
tracking the minor number wasn't necessary as it was already
stored in the heap_devt:
https://android-review.googlesource.com/c/kernel/common/+/1433176/4#message-b07e73548e082ae85b97c3f3ff889ae4ab6ab09d
So this patch reworks those changes so we don't need an extra
minor field in the dma_heap struct.

Commit d25e37d89d ("tracepoint: Optimize using static_call()") changed
the format of DEFINE_TRACE() and other tracepoint logic, which broke the
ANDROID_VENDOR_HOOKS logic.
As I can't figure out how to unwind the build traces for the errors,
disable this for now so the merge can continue.

CPU hotplug operations take place in preemptible context. This leaves
the hotplugging thread at the mercy of overall system load and CPU
availability. If the hotplugging thread does not get an opportunity
to execute after it has already begun a hotplug operation, CPUs can
end up being stuck in a quasi online state. In the worst case a CPU
can be stuck in a state where the migration thread is parked while
another task is executing and changing affinity in a loop. This
combination can result in unbounded execution time for the running
task until the hotplugging thread gets the chance to run to complete
the hotplug operation.
Fix the said problem by ensuring that hotplug can only occur from
threads belonging to the RT sched class. This allows the hotplugging
thread priority on the CPU no matter what the system load or the
number of available CPUs are. If a SCHED_NORMAL task attempts to
hotplug a CPU, we temporarily elevate it's scheduling policy to RT.
Furthermore, we disallow hotplugging operations to begin if the
calling task belongs to the idle and deadline classes or those that
use the SCHED_BATCH policy.
