[Qemu-devel] [PATCH 00/17] pci: switch a ton of drivers to symbolic names

["Michael S. Tsirkin" <mst@redhat.com>]

The recent e1000 bug made the important of using
symbolic macros for pci config access clear for me.
So I started going over drivers and converting
to symbolic constants instead of hard-coded ones.
I did a large part until I run out of steam.
Maybe some brave soul will take up converting
the rest of them, or maybe I will: note that
when converting bridges one should be careful
to use bridge macros where appropriate.

Instead of testing a huge number of configurations,
I compared binaries before and after conversion.
Almost all of them generate exact same stripped binary
before and after the change.
The only object changed was eepro100, objdump showed
that the change was because gcc for some reason
decides to use a bit more stack for init function
after comments are added there.

This methodology was the reason that I added TODOs where I saw
deviations from spec or other code ugliness, will have to be fixed
separately.

I also verified separately that eepro100 still works
and survives light usage.

This patcheset applies on top of e1000 bugfix
I have posted previously.
