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.

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.

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.
