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.

When a buffer is added to the LRU list, a reference is taken which is
not dropped until the buffer is evicted from the LRU list. This is the
correct behavior, however this LRU reference will prevent the buffer
from being dropped. This means that the buffer can't actually be dropped
until it is selected for eviction. There's no bound on the time spent
on the LRU list, which means that the buffer may be undroppable for
very long periods of time. Given that migration involves dropping
buffers, the associated page is now unmigratible for long periods of
time as well. CMA relies on being able to migrate a specific range
of pages, so these these types of failures make CMA significantly
less reliable, especially under high filesystem usage.
Rather than waiting for the LRU algorithm to eventually kick out
the buffer, explicitly remove the buffer from the LRU list when trying
to drop it. There is still the possibility that the buffer
could be added back on the list, but that indicates the buffer is
still in use and would probably have other 'in use' indicates to
prevent dropping.

Zcache could be ineffective if the compressed memory pool is full with
compressed inactive file pages and most of them will be never used again.
So we pick up pages from active file list only, those pages would probably
be accessed again. Compress them in memory can reduce the latency
significantly compared with rereading from disk.
When a file page is shrunk from active file list to inactive file list,
PageActive flag is also cleared.
So adding an extra WasActive page flag for zcache to know whether the
file page was shrunk from the active list.
