net: wireless: bcmdhd: cancel current PNO if connection will happen

	Issue : Manta: Lack of WLS causes PNO problem
	Problem : we found that race condition happens
		between connection and PNO sometimes.
		Connection is failed due to this race condition.
	Solution: we need to cancel PNO explicitly if the connection
	request start in DHD driver.

net: wireless: bcmdhd: Change DTIM skip policy in suspend

	issue : WiFi continuously disconnects
	Root cause :
	Sometimes we got link down event due to beacon
	lost when device goes to suspend.
	This problem sometimes happens in case that DTIM is 3 and beacon
	100ms because we wake up on 900ms (100ms * 3 * 3) during
	suspend.
	This value(900ms) is too big to STA for sync up with AP time.
	This causes STA out of sync for time with the AP.
	Eventually STA got lost of beacon during long time (4secs).

	Solution :
	If the total dtim skip interval (beacon_interval *
	DTIM * 3) is greater than 300ms, we will not extend DTIM to DTIM
	* 3.
	Instead of that, we will use original value (DTIM) for wake up
	in suspend.
	Bug : 1343127 WiFi continuously disconnects

SELinux: include definition of new capabilities

The kernel has added CAP_WAKE_ALARM and CAP_EPOLLWAKEUP.  We need to
define these in SELinux so they can be mediated by policy.

ion: hold reference to handle after ion_uhandle_get

commit 1262ab1846cf76f7549c66ef709120dbfbe6d49f (ion: replace
userspace handle cookies with idr) broke the locking in ion.
The ION_IOC_FREE and ION_IOC_MAP ioctls were relying on
ion_handle_validate to detect the case where a call raced
with another ION_IOC_FREE which may have freed the struct
ion_handle.

Rename ion_uhandle_get to ion_handle_get_by_id, and have it
take the client lock and return with an extra reference to
the handle.  Make each caller put its reference once it
is done with the handle.

Also modify users of ion_handle_validate to continue to hold
the client lock after calling ion_handle_validate until
they are done with the handle, and warn if ion_handle_validate
is called without the client lock held.
