    Subject[git pull] PCI changes for 2.6.30
    Please consider pulling my PCI tree from
    git:// linux-next

    There are some real changes in here, notably Alex's changes to the core to add
    real hotplug support, Matthew's multiple MSI support, and Yu's SR-IOV support.
    Overall, v12n users should be happy with this set of changes. And as is
    customary we got a good collection of fixes from the usual suspects: Kenji-san,
    Yinghai, and Bjorn. Oh and Alpha has support for sysfs PCI resources now,
    thanks to a commit from Ivan.

    I note you've been having some tree management discussions with people this
    time around, so I figured it would be good to describe how I've been handling

    I generally have two branches going: for-linus and linux-next. The for-linus
    branch rarely gets merge commits or rebases. Merges will generally only
    happen if I have some dependencies with another tree (like ACPI), and rebases
    only occur when I need to drop a patch. Other than that it's just fast
    forwards from pulling your tree (after you've pulled mine) and commits for
    new patches.

    I try to keep the linux-next branch a superset of my for-linus branch at the
    request of my downstream developers. This means periodic rebasing after the
    merge window closes, but it's generally important to get your latest stuff
    into that branch so that downstream developers don't have to fight with bugs
    that have been fixed upstream. This isn't pain free (downstream developers
    with large patchsets then have to rebase their stuff) but so far it seems
    like the path of least pain for our purposes, probably because I haven't
    started pulling trees from downstream (yet). If I did, I of course would
    avoid rebasing at that point...

    Anyway hope this pull is ok. I went through every warning by hand to make
    sure none were caused by PCI commits, but that was with the bits in this
    tree, which are -rc8 vintage.
