Revert "usb: gadget: gsi: Decrement USB gadget pm usage count on cable disconnect"

'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.

8 years agofs/buffer.c: Revoke LRU when trying to drop buffers

fs/buffer.c: Revoke LRU when trying to drop buffers

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.

mm: swap_ratio: bail out if there aren't any other swap device

It is pointless to calculate the swap ratio when there is only
one swap device in the group. Moreover the existing code would
result in a spinlock recursion because of not taking this into
consideration. Interestingly, this check is already performed
in swap_ratio_slow by this piece of code

if (&(*si)->avail_list == plist_last(&swap_avail_head)) {
/* just to make skip work */
n = *si;
ret = -ENODEV;
goto skip;
}

But there is window where we drop the swap_avail_lock before
invoking swap_ratio() and take it back again in swap_ratio_slow.
In this period the si can get removed from swap_avail_head,
resulting in the failure of above logic. So recheck again.

Similarly, bail out from swap_ratio() if the sysctl is disabled,
and thus avoiding overhead of taking unnecessary locks.

wil6210: P2P_DEVICE virtual interface support

Added support for the P2P_DEVICE virtual interface. This interface
is intended for P2P management operations such as discovery and
GO negotiation. Normally it is implemented by drivers to allow
a separate interface for P2P management with its own MAC address,
but for 11ad drivers it is needed to support P2P search, since it
cannot otherwise be separated from normal scan.

Since we only support a single interface/MAC address, we can't
easily separate between primary and P2P_DEVICE interfaces.
For example when a management packet arrives we can't tell for
which interface it is intended. To work around this, we store
a pointer to the interface where the last "radio operation" was
triggered such as scan or remain on channel, and we forward
management packets and scan results to this interface.
