Subject: [GIT PULL] PCI updates for 3.5 merge window

Hi Linus,

Please pull the signed tag "pci-for-3.5" to get these PCI changes for the
v3.5 merge window. I'm a newbie, so don't hesitate to help me improve my
pull requests :)

The changes include:
- Host bridge cleanups from Yinghai
- Disable Bus Master bit on PCI device shutdown (kexec-related)
- Stratus ftServer fix
- pci_dev_reset() locking fix
- IvyBridge graphics erratum workaround

Bjorn

Looks fine, except please actually mention the tag itself on the repo
pull line. IOW, not like this:

> ?git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git next

but simply

git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git tags/pci-for-3.5

otherwise it's much too easy for my to just cut-and-paste the line you
supplied without noticing that there was a tag mentioned earlier..

git request-pull seems to look for branches before tags when generating
this text. It just did exactly the same thing for me (since the tag I created
also pointed to my "next" branch).

This would seem to be the common case for people following the rules
and sending you stuff in the merge window that they have had cooking
in linux-next. Can "request-pull" be smarter - or is their some magic I should
be using on the "git request-pull" command line that will tell it that I really
mean the tag and not the branch?

Or is "smarter" already in a newer version of git - I have:

$ git --version
git version 1.7.9.5

I think you want 1.7.10 for anything to do with tagged messages.

You can do everything with 1.7.9 (it can still handle the tags
correctly), but it doesn't DTRT by default: you have to explicitly
mention the "tag" part (ie you need to use "tags/xyz" instead of just
"xyz"), and git pull-request doesn't realize that pulling a signed tag
does more than just pulling the commit it points to etc etc. So with
1.7.9 you can make things work, but you would end up to work around
the fact that the whole signed tag pulling wasn't really a real
feature before that.

So 1.7.10 is when pulling a signed tag was really introduced: it's
just that earlier versions can still *create* those tags (so the only
one who *had* to have 1.7.10 was the person doing the pull).

I would strongly recommend just doing

git clone git://github.com/gitster/git
cd git
make
make install

as just a normal user (*NOT* as root), which will install git in your
~/bin directory. Then, just make sure that you have ~/bin in your PATH
before /usr/bin, and you're all set. No need to mess with or worry
about distro git binaries - leave them alone, but get the best and the
brightest for your own use.

My distro needed some "curl" and "expat" bits added ... but that worked
and I now have shiny new:
$ git --version
git version 1.7.10.2.552.gaa3bb87

which does indeed have a smarter git request-pull.

Thanks
