Larry Finger 996bc370fa b43: Relax requirement for descriptors to be in the DMA zone
When 64-bit DMA was first used, there were problems with the
BCM4311 (14e4:4311). The problem was "fixed" by using the GFP_DMA
flag in the allocation of coherent ring descriptor memory.

The original problem is now believed to have been due to bugs in
the 64-bit DMA implementation in the rest of the kernel, and that
those bugs have been fixed. Accordingly, the requirement for the
descriptors to be in the DMA zone is relaxed.

Bounce buffers are left in the DMA zone.

Michael Büsch 8b0be90c4d b43/legacy: Remove firmware IDs
This removes the "FWxx" ID strings from the b43 and b43legacy
drivers. They were once used to match a specific driver revision
to a set of firmware files. However, this is hardly useful today.
Additionally, the IDs are not updated and maintained properly, so
they might mislead users.

We have resolved all the known issues with DMA mode, however some users
(or distros) are still forcing PIO mode by config files. Without
debugging enabled it's not noticable at all. Add the warning for them.

Johannes Berg 523b02ea23 mac80211: fix TKIP races, make API easier to use
Our current TKIP code races against itself on TX
since we can process multiple packets at the same
time on different ACs, but they all share the TX
context for TKIP. This can lead to bad IVs etc.

Also, the crypto offload helper code just obtains
the P1K/P2K from the cache, and can update it as
well, but there's no guarantee that packets are
really processed in order.

To fix these issues, first introduce a spinlock
that will protect the IV16/IV32 values in the TX
context. This first step makes sure that we don't
assign the same IV multiple times or get confused
in other ways.

Secondly, change the way the P1K cache works. I
add a field "p1k_iv32" that stores the value of
the IV32 when the P1K was last recomputed, and
if different from the last time, then a new P1K
is recomputed. This can cause the P1K computation
to flip back and forth if packets are processed
out of order. All this also happens under the new
spinlock.

Finally, because there are argument differences,
split up the ieee80211_get_tkip_key() API into
ieee80211_get_tkip_p1k() and ieee80211_get_tkip_p2k()
and give them the correct arguments.

Hauke Mehrtens cd15598707 ssb: add __devinit to some functions
Two functions in ssb are using register_pci_controller() which is
__devinit. The functions ssb_pcicore_init_hostmode() and
ssb_gige_probe() should also be __devinit.

This fixes the following warning:
WARNING: vmlinux.o(.text+0x2727b8): Section mismatch in reference from the function ssb_pcicore_init_hostmode() to the function .devinit.text:register_pci_controller()
The function ssb_pcicore_init_hostmode() references
the function __devinit register_pci_controller().
This is often because ssb_pcicore_init_hostmode lacks a __devinit
annotation or the annotation of register_pci_controller is wrong.

FWIW, the usage of these variables is goverened by checks that match

Still, I would rather avoid the warning SPAM...
