If the firmware implements beacon filtering,
beacons are filtered when not associated. This causes
association failures on channels marked passive.
Enabling this flag indicates to the firmware to allow
the beacons to pass through when not associated only.

The __print_symbolic() function takes a sequence of key-value pairs for
pretty-printing a constant. The new kvm:kvm_exit print fmt uses the
expression:
__print_symbolic(..., { 0x040 + 1, "DB excp" }, ...)
Currently only atoms are supported and this print fmt fails to parse.
This patch adds support for expressions instead of just atoms so that
0x040 + 1 is parsed successfully. Also add arg_num_eval() support for
the '+' operator.

Instead of using a global lock, the PCIe transport

The conversion of the ktime to a value suitable for the clock comparator
does not take changes to wall_to_monotonic into account. In fact the
conversion just needs the boot clock (sched_clock_base_cc) and the

Avoid calling wake_up() from our NMI "bottom halve" from RCU extended
quiescent state in idle. wake_up() has RCU read-side critical sections
but this will be completely ignored by RCU if the cpu is in extended
quiescent state.
Which means that whatever object is being accessed from within the
read-side critical section can be freed concurrently from a different
cpu.
So make sure we leave extended quiescent state before calling wake_up().

The previous fix for the speaker on Acer Aspire 59135 introduced
another problem for surround outputs. It changed the connections on
the line-in/mic pins for limiting the routes, but it left the modified
connections. Thus wrong connection indices were written when set to
4ch or 6ch mode.
This patch fixes it by restoring the right connections just after
parsing the tree but before the initialization.
