Hi Jesse,
This is my first pass at cleaning up cpqphp. Why? I dunno, I found
some old hardware and thought it might be fun to clean up a crufty
old driver.
This series is mostly whitespace and style fixes. A few functions
have been reworked so they aren't indented quite so much. I expect
that the first few patches will be very hard to read because there's
so much code movement, but it does help with readability towards the
end of the series.
At the end of the series, we start to see some more interesting
changes. For one, we no longer call pcibios_get_irq_routing_table
nearly as often.
The other is removing the pci_find_slot() interface. I'm still in
the process of untangling exactly what the lifetime rules are for
a pci_dev in cpqphp, but this is a good step forward, and also
finally gets rid of the last in-tree caller of pci_find_slot(), which
would be nice for 2.6.30. Also, this means that cpqphp no longer
depends on PCI_LEGACY.
The current functional state of cpqphp is broken. We are able to load
the module and successfully power off cards. We have some issues when
we try to power them back on though, because commit b81d988c "broke"
cpqphp and we get BAR collisions when we try to hot-add. However, I
use "broke" very loosely, as I agree with Bjorn's commit, and cpqphp
is doing horrible things like essentially duplicating a lot of the
PCI core, incorrectly, I might add. Once I rip out some more of the
PCI code in cpqphp, I expect hot-add to work again.
I plan on untangling that in the next phase of cleanups.
I've successfully tested my changes on my DL580g2. No functional
regressions (compared to behavior since b81d988c).
Anyhow, please consider applying this series for the current merge
window. I'd like to be able to turn off PCI_LEGACY. :)
Thanks!
