Hi Linus,

Please pull these ACPI & Power Management patches.

ACPI 5.0 after-ripples, ACPICA/Linux divergence cleanup cpuidle evolving, more ARM use
thermal sub-system evolving, ditto
assorted other PM bits

The top commit is a merge with your latest tree
to address some cpuidle/ARM conflicts.

Rob, Daniel,

As you both modified at91_enter_idle(), and I don't know the semantics of at91_standby(), I had to guess at the correct merge. Please double check it and correct as necessary.

thanks!
Len Brown, Intel Open Source Technology Center

See this link which I believe is the same conflict on linux-next and Stephen's resolution is verified by me, Daniel, and Nicolas Ferre.

In reply to Len Brown
Quoted 3 lines · Len Brown

The top commit is a merge with your latest tree
to address some cpuidle/ARM conflicts.

Len, *please* don't do this.

I really hate it when submaintainers do merges to resolve things to make things "easier" for me, and they do them wrong.

And I *guarantee* that your merge resolution is wrong. It has references to the sdram_selfrefresh_[en|dis]able() functions that simply no longer exist. There's no way that can compile.

Besides, even if you had done the merge right, I simply want to know about conflicts between different maintainers. As a top-level maintainer, that's the kind of information I need to know.

Finally, people - your merge messages suck. Leaving the list of conflicting files without talking about what the conflict actually was is *not* a good merge message. Len, you're not the only one that does this, but it is yet another reason why I absolutely detest some of the merges I see: they are just very uninformative, and don't add anything useful to the tree - quite the reverse. They hide a problem, without actually talking about what the problem was.

Now, I'm not guaranteeing that I will always do any of the above three things better. I can screw up my merges too. And sometimes I miss non-context merge conflicts that the maintainer may have known about. And yes, sometimes my merge messages suck too (although I've tried very hard to become better at them).

But there's been at least three merges that submaintainers did for me this merge window where I looked at their merge and said "No, that's wrong, and I would have done it better". Two of those were the nice kind of "I left it unmerged, but here's my example merge if you want to take it", so the wrong merges didn't ever show up in the tree. But yours is now no longer even the top commit in your pile of fixes, so now I apparently have to take that *known*incorrect* merge and fix it up with an evil merge of my own.

So once more: please NEVER EVER make my life "easier" by pre-merging stuff. EVER.

Feel free to do your regular octopus-merges of your *own* branches where you just tie your own work together and bundle it up in a nice package. Those merges are beautiful, and makes me go "Ahh, Len did a really nice job keeping all his bugzilla fixes in separate nice branches, and then he packaged it nicely for me too". That's a *good* merge.

But don't go "oops, my changes conflict with somebody elses changes, so let's hide the conflicts under a rug, and send Linus the pre-merged tree so that he can just do a 'git pull' without having to even know about things". That really doesn't make it easier for me.

If you want to make my life easier, the way to do that is:

- have a nice readable history.

This is much easier for me for two reasons:

(a) it makes it much easier for me when I pull, and then look at
the end result, and I go "that all looks nice, this is a maintainer that clearly has it all together". I feel all warm and fuzzy, and I do not get the feeling that I pulled some crap tree. Trust me, that makes me much more comfy about the pull.

(b) when I do end up having to fix up some conflict, good history
without crazy backmerges etc make things *soo* much easier to see what went on in the two conflicting branches. There is a real reason I hate back-merges and ugly history: it really does make things much less obvious.

- You can have a *separate* branch that has your "suggested merge"
for me. Say "here's my 'release' branch with all my work, and this 'merged-for-linus' branch has my suggested merge".

If you do that, I actually tend to do the merge *twice*: first I do
it normally by hand, and then after I'm all done, I will actually re-do it in a local 'test' branch with your suggested merge, and see what the differences are. This is how I noticed that two of the suggested merges in this merge window were incorrect.

This sounds like "more work" for me, but it really isn't. Sure, I'll
do two merges, but the second merge will presumably not have any conflicts, and now I have something I can double-check with. So it's a bit more typing, but it saves me a lot of worries, and I can verify my merge (or I can look at the parts we differed on and think harder about just those, and just assume that the things we agreed on were likely all correct)

So to re-iterate: please don't merge other sub-maintainers' code. That's my job, I'm actually pretty good at it, and even if I were to be no better at it than you are, I'd still want to know about the conflict.

Please.

Ugh. I'm undoing my merge rather than do that evil merge that fixes up yours.

So I have three choices:

(a) I can just re-do your merge, and lose the two commits you had on top of it

(b) I can create a new local branch with your pre-merged state, and
cherry-pick the two commits on top of that, and then merge that, and then fake out the pull request.

(c) I can ask you to do that fix up (rebase those two commits on top
of the state before the broken merge), and then you can ask me to pull again, without the merge - same as (b) really, but I don't have to fake the pull request message when I create the merge.

I think I'll do (c), but then probably fall back on (a) if I don't hear from you. (b) gets me the tree I want, but I don't like faking pull requests - I've occasionally pulled less than requested (exactly because I didn't like the top merge), but I try to avoid actually adding modified commits on top.

[GIT PULL] ACPI & Power Management patches for Linux-3.4-merge - take 2

Hi Linus,

Please pull these ACPI & Power Management patches.

ACPI 5.0 after-ripples, ACPICA/Linux divergence cleanup cpuidle evolving, more ARM use
thermal sub-system evolving, ditto
assorted other PM bits

I have re-merged my tree, adding better comments on the conflict merges. (and getting rid of those reverts that I had piled on top)

thanks!
