* [PATCH] perf_event, powerpc: Fix compilation after big perf_counter rename

  To: Ingo Molnar, Peter Zijlstra; +Cc: linuxppc-dev, linux-kernel

This fixes two places in the powerpc perf_event (perf_counter) code
where 'list_entry' needs to be changed to 'group_entry', but were
missed in commit 65abc865 ("perf_counter: Rename list_entry ->
group_entry, counter_list -> group_list").

This also changes 'event' back to 'counter' in a couple of contexts:

* Field and function names that deal with the limited-function
  counters: it's really the hardware counters whose function is
  limited, not the events that they count.  Hence:

  MAX_LIMITED_HWEVENTS -> MAX_LIMITED_HWCOUNTERS
  limited_event -> limited_counter
  freeze/thaw_limited_events -> freeze/thaw_limited_counters

* The machine-specific PMU description struct (struct power_pmu): this
  renames 'n_event' back to 'n_counter' since it really describes how
  many hardware counters the machine has.  (Renaming this back avoids
  a compile error in each of the machine-specific PMU back-ends where
  they initialize their power_pmu struct.)

Ingo: This is becoming a recurring one now... powerpc build upstream  is

You really aren't build testing other architectures than x86 right ?

Oops, indeed - queued up the fix and will send it to Linus shortly - 
thanks!

On the contrary - i am build testing every architecture on a daily 
basis. (and sometimes i do it multiple times a day - yesterday i did 5 
cross builds during the rename) In fact i am testing more architectures 
than linux-next does.

Here's the log of the test i ran yesterday before i sent those bits to 
Linus:

testing 24 architectures.

In fact there are architectures that dont build in Linus's tree and 
build in -tip:

testing       cris:  -git:  fail (   34),  -tip:  pass (   20)

Because not only do i test every architecture i also try to fix upstream 
bugs on non-x86 pro-actively. See for example this upstream fix:

 8d7ac69: Blackfin: Fix link errors with binutils 2.19 and GCC 4.3

Nevertheless you are right that i should have caught this particular 
PowerPC build bug - i missed it - sorry about that!

Thanks,

Allright. Well, to help in general, we are setting up a build-bot
here too that will build -tip HEAD for at least powerpc daily with
a few configs too.

Cool, that's really useful! Especially during the weekends that will be 
helpful, in that timeframe linux-next driven testing has a latency of 
72-95 hours and -tip usually has an uptick in patches.

ok, seems green for today - the two failures are: one a powerpc 
toolchain problem it appears, plus a mainline warning.

Btw., for me to be able to notice failures there it would have to email 
me automatically if there's any -tip build failures that do not occur 
with the upstream branch. Does it have such a feature?

Yep that looks more or less normal.

Not really, it sends mails to me, but it doesn't have a way to filter
them by branch. I think the plan is we'll keep an eye on it and either
send you patches or at least let you know that it's broken.

how many mails are those per day, typically? If there's not too many and 
if there's a way to send all of them to me i could post-filter them for 
-tip relevance. If that is feasible. You bouncing it to me later is 
certainly also a solution. (but lengthens the latency of fixes, 
obviously.)

Lots of mails - there are an insane number of arm configs for
starters :)

Give me a day or two, I should be able to add a per-branch setting for
who to send mails to without too much trouble.

That's an upstream warning.

-tip supports fail-on-build-warnings build mode (for the whole kernel) 
via the CONFIG_ALLOW_WARNINGS .config setting. So if you do allnoconfig 
builds, make sure you turn on CONFIG_ALLOW_WARNINGS=y to get the same 
build behavior as with Linus's tree.

When I sent that to you, I was referring to these build results:

http://kisskb.ellerman.id.au/kisskb/buildresult/1307802/

which (as you say) was only a waning in the rest of the kernel but is
turned into an error by the -Werror we use when building arch/powerpc.
The warning came from commit 4765c1db84c73f775eb1822a009117cbae524e9e
("rcu-tiny: The Bloatwatch Edition, v6") in the -tip tree and fixed by
commit 5ef9b8e59c043624fb44e31439cecf7f8b4cd62a ("rcu: Clean up the
warning message about RCU not defined") the next day (in the -tip tree).
So no big problem.  Neither of these commits are upstream.

I was just filling in the role of notifying you of build problems until
Michael can automate it.
