tg3: Do not call device_set_wakeup_enable() under spin_lock_bh
The tg3 driver calls device_set_wakeup_enable() under spin_lock_bh,
which causes a problem to happen after the recent core power
management changes, because this function can sleep now. Fix this
by moving the device_set_wakeup_enable() call out of the
spin_lock_bh-protected area.

macb: Don't re-enable interrupts while in polling mode
On a busy network, the macb driver could get stuck in the interrupt
handler, quickly triggering the watchdog, due to a confluence of
factors:
1. macb_poll re-enables interrupts unconditionally, even when it will
be called again because it exhausted its rx budget
2. macb_interrupt only disables interrupts after scheduling
macb_poll, but scheduling fails when macb_poll is already scheduled
because it didn't call napi_complete
3. macb_interrupt loops until the interrupt status register is clear,
which will never happen in this case if the driver doesn't disable
the RX interrupt
Since macb_interrupt runs in interrupt context, this effectively locks
up the machine, triggering the hardware watchdog.
This issue was readily reproducible on a flooded network with a
modified 2.6.27.48 kernel. The same problem appears to still be in the
2.6.36-rc8 driver code, so I am submitting this patch against that
version. I have not tested this version of the patch except to make
sure the kernel compiles.

This updates the initvals for the AR9003 2.2 chipsets. The initvals
are the initial register values we use for our registers upon hardware
reset. This synchs up the initvals to match what our latest recommendation
from our systems engineering team.
The description of changes in this update:
Improves ability to support very strong Rx conditions.
Enhances DFS support for AP-mode.
Improves performance of Tx carrier leak calibration.
Adds support for Japan channel 14 Tx filtering requirements.
Improves Tx power accuracy.
Impact:
Update required to address degraded throughput at very short range.
Update required for AP-mode DFS certification.
Update required to comply to IEEE Tx carrier leak specification.
May not meet expected +/- 2 dB Tx power accuracy without update.
The most important fix here would be the TX carrier leakage required
to comply with IEEE 802.11 specifications. The group of changes have
been tested all together in one release.

netlink: fix netlink_change_ngroups()
commit
6c04bb18ddd633 (netlink: use call_rcu for netlink_change_ngroups)
used a somewhat convoluted and racy way to perform call_rcu().
The old block of memory is freed after a grace period, but the rcu_head
used to track it is located in new block.
This can clash if we call two times or more netlink_change_ngroups(),
and a block is freed before another. call_rcu() called on different cpus
makes no guarantee in order of callbacks.
Fix this using a more standard way of handling this : Each block of
memory contains its own rcu_head, so that no 'use after free' can
happens.

connector: remove lazy workqueue creation
Commit
1a5645bc (connector: create connector workqueue only while
needed once) implements lazy workqueue creation for connector
workqueue. With cmwq now in place, lazy workqueue creation doesn't
make much sense while adding a lot of complexity. Remove it and
allocate an ordered workqueue during initialization.
This also removes a call to flush_scheduled_work() which is deprecated
and scheduled to be removed.

i2c-amd8111: Add proper error handling
The functions the functions amd_ec_wait_write and amd_ec_wait_read have an
unsigned return type, but return a negative constant to indicate an error
condition.
A sematic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@exists@
identifier f;
constant C;
@@
unsigned f(...)
{ <+...
* return -C;
...+> }
// </smpl>
Fixing amd_ec_wait_write and amd_ec_wait_read leads to the need to adjust
the return type of the functions amd_ec_write and amd_ec_read, which are
the only functions that call amd_ec_wait_write and amd_ec_wait_read.
amd_ec_write and amd_ec_read, in turn, are only called from within the
function amd8111_access, which already returns a signed typed value. Each
of the calls to amd_ec_write and amd_ec_read are updated using the
following semantic patch:
// <smpl>
@@
@@
+ status = amd_ec_write
- amd_ec_write
(...);
+ if (status) return status;
@@
@@
+ status = amd_ec_read
