Hi Linus,

One of the sunxi patches from the last pull request was misapplied (I
realized what happened -- git am -s didn't apply cleanly so I had done it
through regular patch, thus not catching the renames properly). Here's
a fresh version of the pull request with a couple more OMAP and Samsung
patches included.

There's a chance that a couple of the OMAP patches will also go in through
Russell, since my connectivity has been crap so far this trip and it
causes build breaks for the platform. It's a branch pull from Tony,
it should be a no-op either way.

ARM: arm-soc fixes for 3.8

This is a batch of fixes for arm-soc platforms. Most of it is for OMAP
but there are others too (Samsung, i.MX, Tegra, ep93xx). Fixes warnings,
some broken platforms and drivers, etc.

So, a bit all over the map really.

Argh!

I pulled your earlier branch due to Tony's ack, and now you're
re-created that branch with new pulls (effectively rebasing it).

Don't do things like this to me.

Yeah, sorry about that -- I wanted to replace the broken patch, and
Tony's branch was based on a newer version of your tree so I brought
everything forward as I had to rebase anyway.

I'll rebuild on top of what you've pulled, and send a fresh request of
just the delta. Sorry about the race condition here.

Sorry for me adding to the confusion too.

Looks like Linus already applied "ARM: OMAP: Fix build breakage due
to missing include in i2c.c" that I had queued earlier.

Olof, I suggest you just merge my pull request up to the other commit
c16acf12 (ARM: OMAP2+: Fix compillation error in mach-omap2/timer.c).
Or just pick it whichever works better for you.

Regards,

Tony

Yeah, since it was my mis-merge, and I realized that I had entirely
missed the header file fixup, I felt like I had to correct it since I
had the report and the pointer to the fix..

Olof,

Not sure what's going on, but my recent pull from arm-soc for-next still
hasn't solved the OMAP build failures in my kbuild - I'm still getting:

arch/arm/mach-omap2/timer.c: In function 'omap_get_timer_dt':
arch/arm/mach-omap2/timer.c:178:3: error: implicit declaration of function 'prom_add_property'

arch/arm/mach-omap2/i2c.c:130:2: error: implicit declaration of function 'omap_pm_set_max_mpu_wakeup_lat'

Yep, I forgot to bring the fixes branch into our for-next. Try again
once it mirrors out, I just pushed out a rebuild of it. New top commit
should be e691d77e8825054376b31e79a9b5f9fa79fe764d.

I'm doing a "build all defconfigs" run before sending the incremental
pull request of fixes to Linus.

Commit e691d77e8825054376b31e79a9b5f9fa79fe764d builds and
boots with my testconfigs.

I'm seeing the "BUG: spinlock bad magic on CPU#0" issue
reported and fixed here:

http://marc.info/?l=linux-arm-kernel&m=135594868503683&w=2

But that's probably been already posted as a proper patch
somewhere?

Regards,

Tony

Yes, this looks much better, thanks.

Hmm. The patch there looks better than any alternative I can think of.
It uses the same spinlock name for the whole array, but I think it's
only used for lockdep printouts, so that should be fine.

Send me the patch with signed-off and tested-by, and perhaps have a
few more people test it. The powerpc and sparc people both use it in
their 32-bit versions and have responsible maintainers, so it might be
worth it double-checking with BenH and DaveM about it, just in case.
Added to the Cc.

Looks like it's been posted to LKML as:

[PATCH] lib: atomic64: Initialize locks statically to fix early users

Replied to it with my tested-by if you want to pick it up.

The patch looks fine. I won't personally be able to test it until after
I'm back from vacation though. I'll see if I can get somebody else to
but don't wait for me.

Cheers,
Ben.
