rt2x00: rt2800: increase EEPROM_SIZE to 512 bytes
Ralink 3T chipsets are using a different EEPROM
layout than the others. The EEPROM on these devices
contain more data than the others which does not fit
into 272 byte which the rt2800 driver actually uses.
The Ralink reference driver defines EEPROM_SIZE to
512/1024 bytes for PCI/USB devices respectively.
Increase the EEPROM_SIZE constant to 512 bytes, in
order to make room for EEPROM data of 3T devices.

iwlwifi: pcie: rework RX buffer list init and freeing
The PCIe code has an array of buffer descriptors (RXBs) that have pages
and DMA mappings attached. In regular use, the array isn't used and the
buffers are either on the hardware receive queue or the rx_free/rx_used
lists for recycling.
Occasionally, during module unload, we'd see a warning from this:
WARNING: at lib/list_debug.c:32 __list_add+0x91/0xa0()
list_add corruption. prev->next should be next (
c31c98cc), but was
c31c80bc. (prev=
c31c80bc).

[<
fdf2dd7a>] iwl_trans_pcie_free+0x2a/0x90 [iwlwifi]
The reason for this seems to be that in iwl_pcie_rxq_free_rbs() we use
the array to free all buffers (the hardware receive queue isn't in use
any more at this point). The function also adds all buffers to rx_used
because it's also used during initialisation (when no freeing happens.)
This can cause the warning because it may add entries to the list that
are already on it. Luckily, this is harmless because it can only happen
when the entire data structure is freed anyway, since during init both
lists are initialized from scratch.
Disentangle this code and treat init and free separately. During init
we just need to put them onto the list after freeing all buffers (for
switching between 4k/8k buffers); during free no list manipulations
are necessary at all.

Bluetooth: Fix multiple LE socket handling
The LE ATT server socket needs to be superseded by any ATT client
sockets. Previously this was done by looking at the hcon->out variable
(indicating whether the connection is outgoing or incoming) which is a
too crude way of determining whether the server socket needs to be
picked or not (an outgoing connection doesn't necessarily mean that an

This patch extends the ATT server socket lookup function
(l2cap_le_conn_ready) to be used for all LE connections (regardless of
the hcon->out value) and adds an internal check into the function for
the existence of any ATT client sockets (in which case the server socket
should be skipped). For this to work reliably all lookups must be done
while the l2cap_conn->chan_lock is held, meaning also that the call to
l2cap_chan_add needs to be changed to its lockless __l2cap_chan_add

Bluetooth: Simplify hci_conn_hold/drop logic for L2CAP
The L2CAP code has been incrementing the hci_conn reference for each
l2cap_chan instance in the l2cap_conn list. Likewise, the reference is
dropped each time an l2cap_chan is removed from the list. The reference
counting policy with respect to removal has been clear and explicit in
the l2cap_chan_del function, however for addition the function
calling 2cap_chan_add has always had to do a separate hci_conn_hold
call.
What made the counting even more hard to follow is that the
hci_connect() procedure increments the reference and the L2CAP layer
making this call took advantage of it to use it as its own reference.
This patch aims to clarify things by having the call to hci_conn_hold
inside __l2cap_chan_add, thereby removing the need to do it in the
functions calling __l2cap_chan_add. The reference count for hci_connect
is still kept as it's necessary for users such as mgmt_pair_device,
however for the L2CAP layer it means that an extra call to hci_conn_drop
must be performed once l2cap_chan_add has been done.

3713b4e364 ("nl80211: allow splitting wiphy

nl80211_fam.attrbuf for parsing the incoming data. This wouldn't

is locked against other commands in generic netlink, but due to
space constraints in cb->args (the needed state doesn't fit) I
decided to always parse the original message. That's racy though
since nl80211_fam.attrbuf could be used by some other parsing in
generic netlink concurrently.
For now, fix this by allocating a separate parse buffer (it's a
bit too big for the stack, currently 1448 bytes on 64-bit). For
-next, I'll change the code to parse into the global buffer in
the first round only and then allocate a smaller buffer to keep

brcmfmac: remove dependency with nl80211.h
The firmware-signalling code used NL80211_NUM_ACS, but it has

to use. This effectively removes the need to include nl80211.h.

brcmfmac: rename variable prec to more appropriate name, ie. fifo
The term prec (precedence) is different from the fifo number. Rename
use of prec with fifo to be consistent and clear.
