o Core changes for Kconfigurable memory and IO resources. By default resources
are 64bit until chosen to be 32bit.
o Last time I posted the patches for 64bit memory resources but it raised
the concerns regarding code bloat on 32bit systems who use 32 bit
resources.
o This patch-set allows resources to be kconfigurable.
o I have done cross compilation on i386, x86_64, ppc, powerpc, sparc, sparc64
ia64 and alpha.

So do these replace all of your other patches sitting in my tree right
now?

No. This patch set applies on top of the old patches.
Very few changes in the previous patches have been nullified, like
changing u64 to resource_size_t. There are lots of printk() statement
changes in previous patch set which are required to supress the compilation
warnings. That's the reason I kept new patches incremental.

I didn't think the bloat was a big issue based on the numbers you
reported. I'd still prefer to see us just move to a 64-bit resource
on all systems.

I had also thought that bloat was not a big issue but Andrew thinks
otherwise. Here is the link to the thread.

http://marc.theaimsgroup.com/?l=linux-kernel&m=114635425606186&w=2
In the latest patches, 64bit resources are default but one can force
these to be 32bit.
Thanks

This may sound like a dumb question, but aside from code bloat, what are
the performance issues involved in running 64-bit resources on 32-bit
systems? AKA, does it kill us x86 users to not have this switch, and by
what kind of margin? You can point if it's been said and I just haven't
found it; I didn't see performance discussion in the last submission.
Thanks!

Unmeasurably minor, I expect.
No sane software project would take on this (small) maintenance burden just
to save 50-60 kbytes. We would though.

I'm aware of that, and I'm not complaining. :) It's one of the things
I love about this project. It's a healthy insanity, enforced by the
squeaking of the wheels. Besides, code bloat is cumulative.
