These bit definitions (CMD_IO_SPACE, CMD_MEMORY_SPACE, etc) are also
generic PCI things that should be replaced with PCI_COMMAND_IO,
PCI_COMMAND_MEMORY, etc.  I haven't looked at the file, but there are
likely more.

These bit definitions (CMD_IO_SPACE, CMD_MEMORY_SPACE, etc) are also
generic PCI things that should be replaced with PCI_COMMAND_IO,
PCI_COMMAND_MEMORY, etc.  I haven't looked at the file, but there are
likely more.

Please also handle the PCI register bit value define duplications as well,

Let's slow this down a little bit; I'm afraid we're going to overwhelm folks.

Before posting more to LKML/netdev, how about we first complete a
sweep of all the drivers to see what we're getting into.  It could be
that this will end up being more churn than it's worth.  You could
send the result to linux-kernel-mentees, Shuah, me (but not LKML and
netdev), and then we can talk about whether it should be posted all at
once, as several series, etc.

I generally disagree.

Consolidation of these sorts of changes are generally
better done treewide all at once, posted as a series to
a list and maintainers allowing time (weeks to months)
for the specific maintainers to accept them and then
whatever remainder exists reposted and possibly applied
by an overall maintainer (e.g.: Dave M)

Also doubtful.

Subsystem specific local PCI #defines without generic
naming is poor style and makes treewide grep and
refactoring much more difficult.

The atlx maintainers should definitely have been cc'd
on these patches.

Jay Cliburn <jcliburn at gmail.com> (maintainer:ATLX ETHERNET DRIVERS)
Chris Snook <chris.snook at gmail.com> (maintainer:ATLX ETHERNET DRIVERS)

Puranjay, can you please do a few things more here:

1: Make sure you use scripts/get_maintainer.pl to cc the
   appropriate people.

2: Show that you compiled the object files and verified
   where possible that there are no object file changes.

3: State that there are no object changes in the proposed
   commit log.

thanks.

Don't worry, we have the same objectives.  I totally agree that local
#defines are a bad thing, which is why I proposed this project in the
first place.

I'm just saying that this is a "first-patch" sort of learning project
and I think it'll avoid some list spamming and discouragement if we
can figure out the scope and shake out some of the teething problems
ahead of time.  I don't want to end up with multiple versions of
dozens of little 2-3 patch series posted every week or two.  I'd
rather be able to deal with a whole block of them at one time.

Do you have any pointers for the best way to do this?  Is it as simple
as comparing output of "objdump -d"?

Do you have any pointers for the best way to do this?  Is it as simple
as comparing output of "objdump -d"?

Hi again Bjorn.

I didn't know that was your idea.  Good idea.

Great, that's sensible.

Also very sensible.

Generically, yes.

I have a little script that does the equivalent of:

<git reset>
make <foo.o>
mv <foo.o> <foo.o>.old
patch -P1 < <foo_patch>
make <foo.o>
mv <foo.o> <foo.o>.new
diff -urN <(objdump -d <foo.o>.old) <(objdump -d <foo.o>.new)

But it's not foolproof as gcc does not guarantee
compilation repeatability.

And some subsystems Makefiles do not allow per-file
compilation.

This should work, but be aware that the older atlx drivers did some
regrettable things with file structure, so not all .c files are
expected to generate a corresponding .o file.

Hi Joe,

I built the object file before the patch named it "atl2-old.o"
then I built it after the patch, named it "atl2-new.o"

then i ran these commands:-
$ objdump -d atl2-old.o > 1
