All three of those are selected in net/wireless/Kconfig, thus they never need to 
be selected by any specific wireless driver. Once you have NET defined, and are 
not building for the S390 architecture, they should be automatic.

That driver has never been in staging - it went directly to mainline in kernel 
2.6.38, i.e. more than two years ago.

As stated earlier, they are not needed in mainline.

I am convinced that this is not a problem for mainline. I have not used any of 
the ARM architectures, and it may be a problem there, but I have no way to test. 
If so, the proper place to submit a patch would be the appropriate ARM tree. 
Make certain that cfg80211 and mac80211 have been selected. If you are still 
having a problem, post the .config that you are using *without* changing any of 
the selection rules for the RTL8192CU.

I have read of alignment problems for the RPi in the lower-level USB routines 
that affect rtl8192cu, but I don't know any of the details.
