Jonas Gorski 072937888e mac80211: make it work with 3.18.12+
3.18.12 backported 61ada528dea028331e99e8ceaed87c683ad25de2 ("sched/wait:
Provide infrastructure to deal with nested blocking") from 3.19, causing
the following error on load:

[   13.588000] compat: exports duplicate symbol woken_wake_function (owned by kernel)

Fix this by guarding it with a check for 3.18.11 or earlier instead of
3.19.

Subject: [PATCH] rt2x00: rt2800lib: add hw_beacon_count field to struct
rt2800_drv_data
Some chipsets can handle more than 8 beacons at once.
Add a new field to the rt2800_drv_data structure which
will hold the number of supported beacons of the given
chipset.
Update the rt2x00_init_registers function to get the
beacon count from the new field instead of using a
hardcoded value.
In order to keep the current behaviour, initialize the
new field with the actually used value.
