My objective is to be able to totally discriminate CAN ports on multi-port
cards via udev so as to rename them to semantically interesting/unique names
for my system (e.g., "ecuCAN" and "auxCAN" instead of "can0" and "can1").
The following patch assigns the dev_id field to match the channel number on all
multi-channel devices. I can only test my two-port Peak PCI card, but it works
as expected: ATTRS{dev_id} now expresses the port number and my udev rules now
unambiguously pick out and rename my individual CAN ports.

In this code, the failure_cleanup label calls the function
plx_pci_del_card, which frees everything in the card->net_dev array. dev
is placed in this array immediately after allocation, so the two subsequent
jumps to failure_cleanup should not also call free_sja1000dev, but the
second one does.
If plx_pci_check_sja1000 fails, then free_sja1000dev is also called on
dev. Because dev is already in the card->net_dev array, this implies that
when plx_pci_del_card is later called, it may get freed again. So that
entry is reset to NULL after the free.
Finally, if there is a problem with one channel, there will be a hole in the
array. card->channels counts the number of channels that have succeeded,
and does not keep track of the index of the largest element in the array
that is valid. So the loop in plx_pci_del_card is changed to go up to
PLX_PCI_MAX_CHAN, which is only 2.

- a new path for PLX9056/PEX8311 chips has been added
- new plx9056 reset function has been implemented
- struct plx_card_info got a reset function entry
In detail the following additional boards are now supported:
CAN-PCI/200 (PCI)
CAN-PCI/266 (PCI)
CAN-PMC266 (PMC module)

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.
