mac80211: optimise station flags
The flaglock in struct sta_info has long been something that I wanted to get rid of, this finally does the conversion to atomic bitops. The conversion itself is straight-forward in most places, a few things needed to change a bit since we can no longer use multiple bits at the same time. On x86-64, this is a fairly significant code size reduction: text data bss dec hex 427861 23648 1008 452517 6e7a5 before 425383 23648 976 450007 6ddd7 after Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.
