Pull more networking updates from David Miller:
 "Ok, everything from here on out will be bug fixes."

1) One final sync of wireless and bluetooth stuff from John Linville.
   These changes have all been in his tree for more than a week, and
   therefore have had the necessary -next exposure.  John was just away
   on a trip and didn't have a change to send the pull request until a
   day or two ago.

2) Put back some defines in user exposed header file areas that were
   removed during the tokenring purge.  From Stephen Hemminger and Paul
   Gortmaker.

3) A bug fix for UDP hash table allocation got lost in the pile due to
   one of those "you got it..  no I've got it.." situations.  :-)

   From Tim Bird.

4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll
   try to coalesce overlapping frags and crash.  Fix from Eric Dumazet.

5) RCU routing table lookups can race with free_fib_info(), causing
   crashes when we deref the device pointers in the route.  Fix by
   releasing the net device in the RCU callback.  From Yanmin Zhang.

bcma: Find names of non BCM cores

2012-05-16T16:45:26+00:00

bcma_device_name only provides names for Broadcom cores.  Modify logic to
provide names for MIPS and ARM cores as well.

bcma: scan for extra address space

2012-04-18T20:43:13+00:00

Some cores like the USB core have two address spaces. In the USB host
controller one address space is used for the OHCI and the other for the
EHCI controller interface. The USB controller is the only core I found
with two address spaces. This code is based on the AI scan function
ai_scan() in shared/aiutils.c in the Broadcom SDK.

bcma: add the core unit number

2012-02-06T19:50:39+00:00

Some SoCs have two pcie or gmac cores and we need to know the number of
the specific core on the bus. This is the case for the BCM4706.

bcma: Fix mem leak in bcma_bus_scan()

2012-02-01T20:24:35+00:00

bcma_bus_scan() leaks 'struct bcma_device' bytes if
bcma_get_next_core() returns error.

Restructure the code so we always kfree() the memory we allocate to
the variable 'core' before it goes out of scope.

bcma: signedness bug in bcma_get_next_core()

2011-08-24T18:41:44+00:00

The u32 would never be less than zero so the error handling would
break.  I changed it to s32 to match how bcma_erom_get_mst_port() is
declared.

bcma: add SOC bus

2011-08-08T18:29:25+00:00

This patch adds support for using bcma on a Broadcom SoC as the system
bus. An SoC like the bcm4716 could register this bus and use it to
searches for the bcma cores and register the devices on this bus.

BCMA_HOSTTYPE_NONE was intended for SoCs at first but BCMA_HOSTTYPE_SOC
is a better name.

bcma: add functions to scan cores needed on SoCs

2011-08-08T18:29:24+00:00

The chip common and mips core have to be setup early in the boot
process to get the cpu clock.
bcma_bus_early_register() gets pointers to some space to store the core
data and searches for the chip common and mips core and initializes
chip common. After that was done and the kernel is out of early boot we
just have to run bcma_bus_register() and it will search for the other
cores, initialize and register them.
The cores are getting the same numbers as before.
