linux-next: Tree for Oct 14

linux-next: Tree for Oct 14

[Thierry Reding]

Hi all,

I've uploaded today's linux-next tree to the master branch of the
repository below:

        git://gitorious.org/thierryreding/linux-next.git

A next-20131014 tag is also provided for convenience.

Gained a few conflicts, but nothing too exciting. x86 and ARM default
configurations build fine. There were some build failures unrelated to
the merge, most of which I fixed and added as patches on top of the
final merge.

linux-next: manual merge of the block tree

[Thierry Reding]

Today's linux-next merge of the block tree got conflicts in

	drivers/md/bcache/bcache.h
	drivers/md/bcache/bset.c
	drivers/md/bcache/journal.c
	drivers/md/bcache/request.c
	drivers/md/bcache/writeback.c

I've fixed them up (see below). Please verify that the resolution looks
good.

Thanks,
Thierry

linux-next: manual merge of the drm-intel tree

[Thierry Reding]

Today's linux-next merge of the drm-intel tree got conflicts in:

	drivers/gpu/drm/i915/i915_dma.c
	drivers/gpu/drm/i915/intel_dp.c
	drivers/gpu/drm/i915/intel_drv.h

caused by commits e1264eb (Revert "drm/i915: Delay disabling of VGA memory
until vgacon->fbcon handoff is done") and ce35255 (drm/i915: Fix unclaimed
register access due to delayed VGA memory disable).

I fixed them up (see below). Please verify that the resolution looks good.

Thanks,
Thierry

linux-next: manual merge of the drm tree

[Thierry Reding]

Today's linux-next merge of the drm tree got conflicts in

	drivers/gpu/drm/i915/intel_drv.h

caused by commits e1264eb (Revert "drm/i915: Delay disabling of VGA memory
until vgacon->fbcon handoff is done"), 20ddf66 (drm/i915: Make
intel_crtc_active() available outside intel_pm.c), 18442d0 (drm/i915: Fix
port_clock and adjusted_mode.clock readout all over), 6878da0 (drm/i915:
Add intel_dotclock_calculate()) and eb14cb7 (drm/i915: Add state readout
and checking for has_dp_encoder and dp_m_n).

I fixed them up (see below). Please verify that the resolution looks good.

Thanks,
Thierry

linux-next: manual merge of th imx-mxs tree

[Thierry Reding]

Today's linux-next merge of the imx-mxs tree got conflicts in:

	arch/arm/mach-imx/clk-imx51-imx53.c
	arch/arm/mach-imx/mach-imx6q.c

caused by commits 0efe995 (ARM: mach-imx: clk-imx51-imx53: Retrieve base
address and irq from dt) and 4d9d18a (ARM: imx: remove custom .init_time
hook).

This looks like the same conflict as last week, only this time I think I
actually fixed it up properly. Please verify that the resolution looks
good.

Thanks,

linux-next: manual merge of the omap_dss2 tree

Today's linux-next merge of the omap_dss2 tree got conflicts in

	drivers/video/omap2/dss/hdmi4_core.c
	drivers/video/omap2/dss/hdmi4_core.h

caused by commits ef26958 (omapdss: HDMI: Rename hdmi driver files to nicer
names) and a few others that I didn't quite track down. But given that the
diff of the merge commit is empty I guess everything's well.

Thanks,

Maybe you could build allmodconfig instead of a default config
for more better coverage?  I am seeing lots of build problems.

I'd say in addition - if you look at the last tree I did it's got fixes
for all these tihngs I think.

This patch makes sense and probably should be merged
but it does not fix the build errors that I reported.

Jean-Christophe has slightly different versions of my patches in his
fbdev for-next branch, so they conflict with my updated versions.

Jean-Christophe, I expected this to happen with the current way of you
having a copy of my for-next branch in yours. Can I now take your
atmel_lcdfb patches to my for-next, and you'll remove all patches from
your for-next?

Ideally I'd be able to run allmodconfig for each merge, but I have
neither the computing power nor the time to do that. I can add
allmodconfig to the set of configurations that I build after the final
merge, but I don't know how much good that is if I don't actually have
any time to fix them up.

Furthermore I'm beginning to think that perhaps we should create some
infrastructure around this that would make it easier to submit requests
for build coverage. Quite a few people seem to run autobuilders, so if
all those could be harnessed to build linux-next (perhaps even on a per
merge basis) that would give great coverage.

It's quite possible that I messed that up during the merge. The bcache
conflicts weren't very trivial. This one in particular seems to be
caused by a commit that went into 3.12-rc5 and one in the block tree's
linux-next branch.

Strange, I didn't see any build fixes in it.

Oh wait, they were applied right after the merges that broke. I hadn't
checked for that.

Yeah, it's because I've been doing incremental build checks - the builds
fail at the point the tree gets merged in.

No, the linux-next maintainers.

The driver maintainers have nothing to do with this, it's a sysfs change
in my driver-core tree that causes this issue.

Well, we do carry a patch to fix this, but that generally doesn't get
carried to Linus' tree automatically as far as I know. So I guess it's
fine for now, but when the merge window opens you'll need to make sure
that Linus merges the branches in the correct order so that the build
doesn't break in between.

I think the typical way to solve this kind of build dependencies between
trees is for one tree to provide a stable branch that can be merged into
the other. That ensures that each tree can still be built independently.

Yes, I'll do that as part of my normal tree submission process.

I don't do that for my different trees, sorry, especially for staging
drivers, they can break all the time, no one really cares :)

Yeah.  This one was one of the ones that went AWOL for a few days due to
being in the middle of the trees I'd produced (due to me doing the
merges).

Actually, ensuring correct merge order won't be enough, will it? That
doesn't magically fixes that the function's signature actually changed.

Shouldn't the update of the sysfs_get_dirent() call be fixed within the
same patch that updates the sysfs_get_dirent() signature?

Yes, _if_ those files are actually part of that tree, but they aren't
(they got added in my staging-next tree, while these sysfs changes are
in my driver-next tree.)

So the trees on their own build just fine, it's only when you merge them
that there is an issue.  This happens all the time when apis change,
nothing new here...

They're applied in different trees so they're both OK by themselves,
it's the merge that brings the two together that needs to do the fixup.

Right, as long as the person doing that merge remembers to do that. It
sounds like the thing that could easily be forgotten. But Linus has been
doing this for a long time, so I'm sure he'll know what to look for. I'm
curious though, are maintainers supposed to mention it when sending pull
requests with such a dependency?

Sometimes, if we remember, we do, sometimes we don't :)
