__napi_schedule might raise softirq but nothing
causes do_softirq to trigger, so it does not in fact
run. As a result,
the error message "NOHZ: local_softirq_pending 08"
sometimes occurs during boot of a KVM guest when the network service is
started and we are oom:
...
Bringing up loopback interface: [ OK ]
Bringing up interface eth0:
Determining IP information for eth0...NOHZ: local_softirq_pending 08
done.
[ OK ]
...
Further, receive queue processing might get delayed
indefinitely until some interrupt triggers:
virtio_net expected napi to be run immediately.
One way to cause do_softirq to be executed is by
invoking local_bh_enable(). As __napi_schedule is
normally called from bh or irq context, this
seems to make sense: disable bh before __napi_schedule
and enable afterwards.
In fact it's a very complicated way of calling do_softirq(),
and works since this function is only used when we are not
in interrupt context. It's not hot at all, in any ideal scenario.

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.

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.

It gets rid of:

- 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.
- any associated token ring documentation.

hdr = (struct ieee80211_hdr_3addr *)skb_push(skb, sizeof(*hdr));

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.
