mac80211: add PS flag to bss_conf
Currently, ps mode is indicated per device (rather than
per interface), which doesn't make a lot of sense.
Moreover, there are subtle bugs caused by the inability
to indicate ps change along with other changes
(e.g. when the AP deauth us, we'd like to indicate
CHANGED_PS | CHANGED_ASSOC, as changing PS before
notifying about disassociation will result in null-packets
being sent (if IEEE80211_HW_SUPPORTS_DYNAMIC_PS) while
the sta is already disconnected.)
Keep the current per-device notifications, and add
parallel per-vif notifications.
In order to keep it simple, the per-device ps and
the per-vif ps are orthogonal - the per-vif ps
configuration is determined only by the user
configuration (enable/disable) and the connection
state, and is not affected by other vifs state and
(temporary) dynamic_ps/offchannel operations
(unlike per-device ps).

still start the beacon loss timer and if a few beacons

If the hardware doesn't advertise connection monitoring,

powerpc is also behind in this fix.
The commit
722b3c746953 "ftrace/graph: Trace function entry before
updating index" fixes an issue with function graph tracing for x86,
where if the called entry function decides not to trace interrupts, it
can fail the check if an interrupt comes in just after the
curr_ret_stack is updated.
The solution is to call the entry function first, then update the
curr_ret_stack if the entry function wants to be traced.
