wait_cons_dev waits for a particular subchannel to complete an I/O.
It is not necessary to use tpi to get the subchannel id as it is
already known. This avoids changes to the interrupt subclass mask
and allows to remove the lock & unlock of the subchannel lock.

Various improvements of qdio error reporting to the
upper-layer drivers (qeth, zfcp):
- Split QDIO_ERROR_ACTIVATE_CHECK_CONDITION into:
QDIO_ERROR_ACTIVATE: qdio termination interrupt
QDIO_ERROR_GET_BUF_STATE: QIOASSIST eqbs error
QDIO_ERROR_SET_BUF_STATE: QIOASSIST sqbs error
Add QDIO_ERROR_FATAL / QDIO_ERROR_TEMPORARY masks
to ease recovery decision in upper-layer drivers.
- Don't (ab-)use qdio handler errors as return codes
for do_QDIO but use standard error codes:
-ENOBUFS: temporary target CC=2 condition
-EBUSY: unresolved SIGA-W CC=2 busy condition
-EIO: I/O error (CC=1, CC=3)
- Remove unneeded memory clobber from SIGA-R
- Remove EX_TABLE entry on SIGA-W, we want to see these errors

John Linville says:
Here are three more fixes that some of my developers are desperate to
see included in 3.4...
Johan Hedberg went to some length justifyng the inclusion of these two
Bluetooth fixes:
"The device_connected fix should be quite self-explanatory, but it's
actually a wider issue than just for keyboards. All profiles that do
incoming connection authorization (e.g. headsets) will break without it
with specific hardware. The reason it wasn't caught earlier is that it
only occurs with specific Bluetooth adapters.
As for the security level patch, this fixes L2CAP socket based security
level elevation during a connection. The HID profile needs this (for
keyboards) and it is the only way to achieve the security level
elevation when using the management interface to talk to the kernel
(hence the management enabling patch being the one that exposes this"
The rtlwifi fix addresses a regression related to firmware loading,
as described in kernel.org bug 43187. It basically just moves a hunk
of code to a more appropriate place.

unload
Currently the slave and master resources are deleted after master freed
all bitmaps. If any resources were not properly cleaned up during the
shutdown process, an Oops would result.
Fix so that delete slave (only) resources during cleanup. Master resources
are cleaned up during unload process, and need not separately be cleaned.
Note that during cleanup, we need to split the resource-tracker freeing
functionality.
Before removing all the bitmaps, we free any leftover slave resources.
However, we can only remove the resource tracker linked list after
all bitmap frees, since some of the freeing functions (e.g.,
mlx4_cleanup_eq_table) use paravirtualized FW commands which expect
the resource tracker linked list to be present.

Consider the following scenario: 2 HCAs, where only one of which can run SRIOV.
If we reset the module parameter, all the VFs of the SRIOV HCA will be
claimed by the PPF host (-- the code relies on num_vfs being non-zero
to avoid this claiming, and num_vfs was reset when pci_enable_sriov failed
for the non-SRIOV HCA).
The solution is not to touch the num_vfs parameter.
Also, eliminate the unneeded check of num_vfs when disabling sriov
(the dev flag bit is sufficient).

In function mlx4_INIT_PORT_wrapper, the port state mask for the
slave is only set if we are invoking the INIT_PORT fw command.
However, the reference count for the (initialized) port is
incremented anyway.
This creates a problem in that when we have multiple slaves,
then the CLOSE_PORT command will never be invoked. The
reason is that in the CLOSE_PORT wrapper, if the port-state
mask is zero for the slave (which it is), the wrapper returns
without doing anything. The only slave which will not return
immediately in the CLOSE_PORT wrapper is that slave for which
INIT_PORT was invoked.
The fix is to not have the port-state mask setting depend
on the logic for calling the INIT_PORT fw command.

This represents the mass deletion of the of the tokenring support.
It gets rid of:
- the net/tr.c which the drivers depended on
- the drivers/net component
- the Kbuild infrastructure around it
- any tokenring related CONFIG_ settings in any defconfigs
- the tokenring headers in the include/linux dir
- the firmware associated with the tokenring drivers.

We currently do this:

...
struct wl12xx_arp_rsp_template *tmpl;
struct ieee80211_hdr_3addr *hdr;
...
tmpl = (struct wl12xx_arp_rsp_template *)skb_put(skb, sizeof(*tmpl));
memset(tmpl, 0, sizeof(tmpl));
...
hdr = (struct ieee80211_hdr_3addr *)skb_push(skb, sizeof(*hdr));
memset(hdr, 0, sizeof(hdr));

memset() calls, not just zero the initial part of them (size of the

This patch fixes multiple issues with the current RTT
implementation in ath9k.
* The data that is obtained from the RTT interface registers
are stored in 31:5 - mask out the extra bits when reading them.
* A history buffer is maintained which is not needed at all.
Remove this array and just store the baseband data for each
chain (or bank).
* A 'num_readings' variable was being used to handle the
last entry. But it was being used in an improper manner, with
the result that the RTT values were never being written
to the RTT Interface registers. Fix this by using a simple
flag.
* Stop baseband operations before programming the calibration values
to the HW.
* Do not restore RX gain settings as part of RTT.
