This has always been unused feature given its limitation of adding
phantom load to the system. Since there are no immediate plans of
using this and the fact that it adds unnecessary complications to
the new load fixup mechanism, remove this feature for now. It can
be revisited later in light of the new mechanism.

For multi-rect pipes, driver tries to release the
pipe only when both pipes for both rectangles
are in the destroy list. Current code always
detects that there are two pipes with the same
number in the list, since the first iteration to
look for the pipe in the list always correspond to
the same pipe used as the initial index.
This causes that driver unnecesary halt the dma pipe
when still in use for the second rect that is still not
freed. Fix this issue by making sure the same pipe
objects are not used to check if there are two pipes
with the same index in the release list.

There is a use-after-free problem in the ion driver.
This is caused by a race condition in the ion_ioctl()
function.
A handle has ref count of 1 and two tasks on different
cpus calls ION_IOC_FREE simultaneously.
cpu 0 cpu 1
-------------------------------------------------------
ion_handle_get_by_id()
(ref == 2)
ion_handle_get_by_id()
(ref == 3)
ion_free()
(ref == 2)
ion_handle_put()
(ref == 1)
ion_free()
(ref == 0 so ion_handle_destroy() is
called
and the handle is freed.)
ion_handle_put() is called and it
decreases the slub's next free pointer
The problem is detected as an unaligned access in the
spin lock functions since it uses load exclusive
instruction. In some cases it corrupts the slub's
free pointer which causes a mis-aligned access to the
next free pointer.(kmalloc returns a pointer like
ffffc0745b4580aa). And it causes lots of other
hard-to-debug problems.
This symptom is caused since the first member in the
ion_handle structure is the reference count and the
ion driver decrements the reference after it has been
freed.
To fix this problem client->lock mutex is extended
to protect all the codes that uses the handle.

When start_hwmon() runs with another thread trying to hotplug a
CPU the two threads can enter a deadlock situation as follows:
Thread A (start_hwmon()) Thread B (CPU down)
get_online_cpus()
|
atomic_inc(&cpu_hotplug.refcount)
CPU down
|
mutex_lock(&cpu_add_remove_lock)
|
cpu_hotplug_begin() waits on
cpu_hotplug.refcount to reset
register_cpu_notifier()
|
mutex_lock(&cpu_add_remove_lock)
With this change the notifers are registered and unregistered per
device rather than having a common notifier block for all the memlat
devices and unregistration only happens on stop_hwmon. This makes it
possible to move the registration outside the hotplug lock without
any race between multiple memlat devices.

'commit 3a7ce1db5661 ("usb: gadget: gsi: Decrement USB gadget pm usage
count on cable disconnect")' added decrementing USB gadget device's pm
usage count from STATE_INITIALIZED which results into multiple time
decrementing USB gadget device's pm usage count on USB cable disconnect
as below:
1. On USB cable disconnect, USB bus suspend event is being received which
post EVT_DISCONNECTED. If state is STATE_CONNECTED, ipa_work_handles()
decrements USB gadget device's pm usage count, and move state to
STATE_INITIALIZED.
2. Due to USB cable disconnect, gsi_disable() posts EVT_DISCONNECTED.
This event is processed into STATE_CONNECTED causing additional decrement
of USB gadget device's pm usage count.
Due to above case, USB goes into low power mode with dwc3's pm usage
count negative. On connecting USB host mode cable, xhci resume is failing
due to dwc3's (parent of xhci) is having negative usage count which results
into no USB host mode functionality (pm_runtime_get_sync() returns -EBUSY).
Hence revert commit to allow USB Host mode functionality.
