Small merge conflict in net/mac80211/scan.c, I preserved
the kcalloc() conversion. -DaveM

Johannes Berg says:

====================
This round's updates:
 * finally some of the promised HE code, but it turns
   out to be small - but everything kept changing, so
   one part I did in the driver was >30 patches for
   what was ultimately <200 lines of code ... similar
   here for this code.
 * improved scan privacy support - can now specify scan
   flags for randomizing the sequence number as well as
   reducing the probe request element content
 * rfkill cleanups
 * a timekeeping cleanup from Arnd
 * various other cleanups
====================

This file was scheduled to be removed in 2014, but due to its
large number of users it will be sticking around for a bit
longer. Despite it being marked as stabe, the newer "hard" and
"soft" interfaces should be preffered, since it is not possible
longer. Despite it being marked as stable, the newer "hard" and
"soft" interfaces should be preferred, since it is not possible
to express the 'soft and hard block' state of the rfkill driver
through this interface. There will likely be another attempt to
remove it in the future.
