arcnet: restoring support for multiple Sohard Arcnet cards

commit 5ef216c1f848 ("arcnet: com20020-pci: add rotary index support")
changes the device name of all COM20020 based PCI cards,
even if only some cards support this:
snprintf(dev->name, sizeof(dev->name), "arc%d-%d", dev->dev_id, i);

The error happens because all Sohard Arcnet cards would be called arc0-0,
since the Sohard Arcnet cards don't have a PLX rotary coder.
I.e. EAE Arcnet cards have a PLX rotary coder,
which sets the first decimal, ensuring unique devices names.

This patch adds two new card feature flags to indicate
which cards support LEDs and the PLX rotary coder.
For EAE based cards the names still depend on the PLX rotary coder
(untested, since missing EAE hardware).
For Sohard based cards, this patch will result in devices
being called arc0, arc1, ... (tested).

net: arcnet: com20020: Fix null-ptr-deref in com20020pci_probe()

During driver initialization, the pointer of card info, i.e. the

1. priv might be not initialized yet when calling com20020pci_remove()
from com20020pci_probe(), since the priv is set at the very last but it
can jump to error handling in the middle and priv remains NULL.
2. memory leak - the net device is allocated in alloc_arcdev but not
properly released if error happens in the middle of the big for loop

net: arcnet: Fix RESET flag handling

The main arcnet interrupt handler calls arcnet_close() then
arcnet_open(), if the RESET status flag is encountered.

This is invalid:

1) In general, interrupt handlers should never call ->ndo_stop() and
->ndo_open() functions. They are usually full of blocking calls and
other methods that are expected to be called only from drivers
init and exit code paths.

2) arcnet_close() contains a del_timer_sync(). If the irq handler
interrupts the to-be-deleted timer, del_timer_sync() will just loop
forever.

3) arcnet_close() also calls tasklet_kill(), which has a warning if
called from irq context.

4) For device reset, the sequence "arcnet_close(); arcnet_open();" is
not complete. Some children arcnet drivers have special init/exit
code sequences, which then embed a call to arcnet_open() and
arcnet_close() accordingly. Check drivers/net/arcnet/com20020.c.

Run the device RESET sequence from a scheduled workqueue instead.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

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.

2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it

This patch is a safe convert for netdev->priv to netdev_priv(netdev).
Since all of the netdev->priv is only for read.

bugfixes and new hardware support for arcnet driver

The modifications and bug fixes noted below were done by Realtime Control
Works and Contemporary Control Systems, Inc, Jan 2005. They were
incorporated into the 2.6 kernel by Jeff Morrow of Sierra Analytics, Feb
2007. <jmorrow@massspec.com>

The changes have been tested on a Contemporary Controls PCI20U-4000.

Summary of changes:

Arc-rawmode.c:
rx():
- Fixed error in received packet lengths; 256 byte packets were
being received as 257 bytes packets.

prepare_tx():
- Fixed error in transmit length calcs; 257 byte packets were being
transmitted as 260 byte packets.

com20020.c:
com20020_check():
- We now load the SETUP2 register if the 'clockm' parameter is
non-zero, instead of checking for ARC_CAN_10MBIT. The user is
now responsible for whether or not SETUP2 is loaded. If the
clock multiplier is non-zero, this means that the user wants a
baud rate greater than 2.5Mbps. This is not possible unless the
SETUP2 register is present (COM20020D, or COM20022). So, we're
relying on the user to be smart about what kind of chip he's
dealing with...

com20020-pci.c
- Added several entries to com20020pci_id_table[].

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
