Incresed the timeout value for command complete event waiting from 100
ms to 750 ms. In some rare cases it can take about 600 ms before
complete event for join command is received. This is most propably
caused by the firmware being busy with scanning related activities.

This patch changes the way JOIN's are performed, and channel numbers updated.
The reason for this is that the firmware JOIN command clears WPA(2) key
material, and if done while associated to a WPA(2) secured AP, will render
the data-path unusable.
While the channel is not usually changed while associated (and currently we
could not even support something like that), after performing a scan operation
while associated, mac80211 will re-set the current channel to the driver. This
caused our problem.
Also, the mac80211 is assuming that the driver channel configuration remains
persistent over periods of IDLE. Therefore remove channel resetting to zero
from the unjoin function.

The driver had a join command without keep-alive restart procedures in the
channel changing code. After associated scans, the mac80211 does re-set the
current channel, causing the join to occur. This would stop the hardware
keep alive.
To make the joins safer in this respect, this patch adds a join function that
does the hardware-keep-alive magic along the join. This is now invoked in the
above mentioned scenario, and also other scenarios.

In testing I noticed that the wl1271 commands fall into two categories. In the
first category are "fast" commands, these mostly take only 0 or 1 polls to

second category, the command completion takes well more than 0.5ms (from
1.5ms upwards.)
This patch fixes command polling such that it is optimal for the fast commands,

percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

Currently the PSM entry function assumes successful operation, and enables
ELP, BET and beacon filtering right away. This is bad, because the PSM
entry may fail due to environmental issues, which will cause the ELP, BET and

Fix this by enabling ELP, BET and beacon filtering only after successful entry,

We were missing the command header in the radio and general parameters
commands. This was causing them to fail, resulting in problems in the power
levels and other PLT-related commands.
Also reorganized the command functions, moving from wl1271_init.c to
wl1271_cmd.c where it fits better.

The wl1271_dev_notify() was returning 0 or -ENODEV, when it should return
NOTIFY_* instead. Now we use NOTIFY_DONE when we didn't handle the event or
NOTIFY_OK when we have handled it.
For inetdev notifications, it doesn't matter whether we use NOTIFY_DONE or
NOTIFY_OK, because it ignores the return value of the call to
blocking_notifier_call_chain(). But the notify.h header says that
NOTIFY_DONE is "Don't care" and NOTIFY_OK is "Suits me", so that seems to be
the right way to do it.

- It works around a firmware race condition if ELP is entered too fast

- It will reduce the number of sleep-wake cycles between already
scheduled events such as interrupts and tx, hence improving
