mac80211: fix suspend/resume races with unregister hw
Above commit add rtnl_lock() into wiphy_register(), what cause deadlock
when initializing ipw2x00 driver, which itself call wiphy_register()
from register_netdev() internal callback with rtnl mutex taken.
To fix move wiphy_register() outside register_netdev(). This solution
have side effect of not creating /sys/class/net/wlanX/phy80211 link,
but that's a minor issue we can live with.

This is an attempt to fix a long standing open bug:
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1334
The interrupt handler checks for INTA being -1, apparently that means that the
hardware is gone. But the interrupt handler defers actual interrupt processing
to a tasklet. By the time the tasklet is run and checks INTA again, the
hardware might be gone and INTA be -1, which confuses the driver because all
event bits are set.
The patch applies to 2.6.37.

Commit 27ae60f8f7 ("ipw2x00: replace "ieee80211" with "libipw" where
appropriate") changed DRV_NAME to be "libipw", but didn't properly fix
up the places where it was used to specify the name for the /proc/net/
directory.
For backwards compatibility reasons, that directory name remained
"ieee80211", but due to the DRV_NAME change, the error case printouts
and the cleanup functions now used "libipw" instead. Which made it all
fail badly.
For example, on module unload as reported by Randy:
WARNING: at fs/proc/generic.c:816 remove_proc_entry+0x156/0x35e()
name 'libipw'
because it's trying to unregister a /proc directory that obviously
doesn't even exist.
Clean it all up to use DRV_PROCNAME for the actual /proc directory name.

This patch changes the string based list management to a handle base
implementation to help with the hot path use of pm-qos, it also renames
much of the API to use "request" as opposed to "requirement" that was
used in the initial implementation. I did this because request more
accurately represents what it actually does.
Also, I added a string based ABI for users wanting to use a string
interface. So if the user writes 0xDDDDDDDD formatted hex it will be
accepted by the interface. (someone asked me for it and I don't think
it hurts anything.)
This patch updates some documentation input I got from Randy.

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
* alpha SMP allmodconfig
* um on x86_64 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.

Refactor wext to
* split out iwpriv handling
* split out iwspy handling
* split out procfs support
* allow cfg80211 to have wireless extensions compat code
w/o CONFIG_WIRELESS_EXT
After this, drivers need to
- select WIRELESS_EXT - for wext support
- select WEXT_PRIV - for iwpriv support
- select WEXT_SPY - for iwspy support
except cfg80211 -- which gets new hooks in wext-core.c
and can then get wext handlers without CONFIG_WIRELESS_EXT.
Wireless extensions procfs support is auto-selected
based on PROC_FS and anything that requires the wext core
(i.e. WIRELESS_EXT or CFG80211_WEXT).

Mostly just simple conversions:
* ray_cs had bogus return of NET_TX_LOCKED but driver
was not using NETIF_F_LLTX
* hostap and ipw2x00 had some code that returned value
from a called function that also had to change to return netdev_tx_t

Initiate the conversion of libipw to the new cfg80211 configuration API.
For now, leave CONFIG_IPW2200_PROMISCUOUS stuff alone. Eventually
migrate it to cfg80211 when the add/del/change_virtual_intf methods
are implemented.

This eliminates the dual definition of ieee80211_channel (and possibly
others), further clarifying who defines what and paving the way for
inclusion of cfg80211.h.

Bartlomiej Zolnierkiewicz reported an atomic order-6 allocation failure
for ipw2200 firmware loading in kernel 2.6.30. High order allocation is
likely to fail and should always be avoided.
The patch fixes this problem by replacing the original order-6
pci_alloc_consistent() with an array of order-1 pages from a pci pool.
This utilized the ipw2200 DMA command blocks (up to 64 slots). The
maximum firmware size support remains the same (64*8K).

The result of container_of should not be NULL. In particular, in this case
the argument to the enclosing function has passed though INIT_WORK, which
dereferences it, implying that its container cannot be NULL.
A simplified version of the semantic patch that makes this change is as
follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@
identifier fn,work,x,fld;
type T;
