[PATCH v3] move brcm80211 drivers to mainline

[Arend van Spriel]

With number of cleanup patch series merged in by Greg KH, I'd like to
once again propose moving brcm80211 out of staging and into mainline.

I've put together a patch to add a copy of the current sources from
staging-next into drivers/net/wireless/brcm80211 of the wireless-next
repository.

The patch is somewhat large, so I've posted the patch at:

http://linuxwireless.org/en/users/Drivers/brcm80211?action=AttachFile&do=view&target=0001-net-wireless-add-brcm80211-drivers-v3.patch

Changes from the previous version:

V3:
- remove -D line from Makefiles
- use endian annotated structures
- enable sparse endian checking
- remove use of (static) global variables
- remove own buffer printing implementation
- remove static function prototypes
- replace macros by inline functions
- reduce sparse warnings
- remove using string-based iovars
- remove driver internal use of ioctls
- remove (un)likely
- remove uncoditional curly braces for variable scoping
- remove error messages upon alloc failures
- reduced code indentation levels
- cleanup in brcmutil module
- remove changing lock state which is acquired by other layer 
(wpa_supplicant)
- brcmfmac:
     - use ffs() instead of brcmf_find_msb()
     - replace threads with work queues
     - cleanup module parameters
- brcmsmac:
     - not modifying ssn value upon AMPDU start
     - use hweight8() instead of brcmu_bitcount()
     - remove unnecessary mac80211 callbacks
     - remove brcms_c_set_par and get_par functions
     - remove bmac wrapper functions
     - remove lock related macros
     - add debugfs based event tracing (not functional in staging)

The brcmsmac driver has been verified to work on x86 (both 32- and 
64-bit), PPC
(64-bit), SPARC, MIPS BE, and ARM.  The brcmfmac driver has been verified to
work on x86 32-bit and ARM (additional testing is in progress, but getting a
working sdio controller on some of the other platforms remains challenging).

The drivers compile cleanly for x86 (32- and 64-bit), PPC (32- and 64-bit),
SPARC, MIPS BE, MIPS LE, and ARM.

Thanks,
