As a fourth step, remove any remaining usages of
dev_node_t from drivers:
- ipwireless can be simplified a bit, as we do not need
to pass around the (write-only) dev_node_t around.
- avma1_cs can be simplified as well, if we only keep the
minor number around as "priv" data, not a full-fledged
struct.

Instead of the old pcmcia_request_irq() interface, drivers may now
choose between:
- calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.
- use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
clean up automatically on calls to pcmcia_disable_device() or
device ejection.
- drivers still not capable of IRQF_SHARED (or not telling us so) may
use the deprecated pcmcia_request_exclusive_irq() for the time
being; they might receive a shared IRQ nonetheless.

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.

Most of the irq_req_t typedef'd struct can be re-worked quite
easily:
(1) IRQInfo2 was unused in any case, so drop it.
(2) IRQInfo1 was used write-only, so drop it.
(3) Instance (private data to be passed to the IRQ handler):
Most PCMCIA drivers using pcmcia_request_irq() to actually
register an IRQ handler set the "dev_id" to the same pointer
as the "priv" pointer in struct pcmcia_device. Modify the two
exceptions (ipwireless, ibmtr_cs) to also work this waym and
set the IRQ handler's "dev_id" to p_dev->priv unconditionally.
(4) Handler is to be of type irq_handler_t.
(5) Handler != NULL already tells whether an IRQ handler is present.
Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
irq_req_t.Attributes.

Convert PCMCIA drivers to use the dynamic debug infrastructure, instead of
requiring manual settings of PCMCIA_DEBUG.
Also, remove all usages of the CS_CHECK macro and replace them with proper
Linux style calling and return value checking. The extra error reporting may
be dropped, as the PCMCIA core already complains about any (non-driver-author)
errors.

Wireless USB endpoint state has a sequence number and a current
window and not just a single toggle bit. So allow HCDs to provide a
endpoint_reset method and call this or clear the software toggles as
required (after a clear halt, set configuration etc.).
usb_settoggle() and friends are then HCD internal and are moved into
core/hcd.h and all device drivers call usb_reset_endpoint() instead.
If the device endpoint state has been reset (with a clear halt) but
the host endpoint state has not then subsequent data transfers will
not complete. The device will only work again after it is reset or
disconnected.

a) hisax_init_pcmcia() needs to be defined only if we have
CONFIG_HOTPLUG (no PCMCIA support otherwise) and can be declared
__devinit.
b) HiSax_inithardware() can go __init
c) hisax_register() is passing to checkcard() full-blown hisax_cs_setup_card():
checkcard(i, id, NULL, hisax_d_if->owner, hisax_cs_setup_card);
The problem with it is that
* hisax_cs_setup_card() is __devinit
* hisax_register() is not
* hisax_cs_setup_card() is a switch from hell, calling a lot of
setup_some_weirdcard() depending on card->typ. _These_ are also
__devinit.
However, in hisax_register() we have card->typ equal to
ISDN_CTYPE_DYNAMIC, which reduces hisax_cs_setup_card() to "nevermind
all that crap, just do nothing and return 2". So we add a
trimmed-down callback doing just that and passed to checkcard() by
hisax_register(). _This_ is non-init (we can stand the impact on
.text size).
