Hi all,

Changes since 20151207:

Undropped tree: cgroup

The vfs tree gained a conflict against the s390 tree and a build failure
so I used the version from next-20151207.

The drm-misc tree gained a build failure so I used the version from
next-20151207.

The gpio tree still had its build failure, so I used the version from
next-20151127 for today.

Non-merge commits (relative to Linus' tree): 4217
 4833 files changed, 174427 insertions(+), 73667 deletions(-)

----------------------------------------------------------------------------

I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
(patches at http://www.kernel.org/pub/linux/kernel/next/ ).  If you
are tracking the linux-next tree using git, you should not use "git pull"
to do so as that will try to merge the new linux-next release with the
old one.  You should use "git fetch" and checkout or reset to the new
master.

You can see which trees have been included by looking in the Next/Trees
file in the source.  There are also quilt-import.log and merge.log
files in the Next directory.  Between each merge, the tree was built
with a ppc64_defconfig for powerpc and an allmodconfig for x86_64, a
multi_v7_defconfig for arm and a native build of tools/perf. After the
final fixups (if any), I do an x86_64 modules_install followed by builds
for powerpc allnoconfig (32 and 64 bit), ppc44x_defconfig, allyesconfig
(this fails its final link) and pseries_le_defconfig and i386, sparc,
sparc64 and arm defconfig.

Below is a summary of the state of the merge.

I am currently merging 231 trees (counting Linus' and 36 trees of patches
pending for Linus' tree).

Stats about the size of the tree over time can be seen at
http://neuling.org/linux-next-size.html .

Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next .  If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.

Thanks to Randy Dunlap for doing many randconfig builds.  And to Paul
Gortmaker for triage and bug fixes.

Cheers,

    EDAC: Rip out the edac_subsys reference counting

    This was really dumb - reference counting for the main EDAC sysfs
    object. While we could've simply registered it as the first thing in the
    module init path and then hand it around to what needs it.

    Do that and rip out all the code around it, thus simplifying the whole
    handling significantly.

    Move the edac_subsys node back to edac_module.c.

    Signed-off-by: Borislav Petkov <bp@suse.ede>



Presumably caused by the fact that edac_init() is subsys_initcall(), whereas
corenet_gen_publish_devices() is arch_initcall().

Thanks for the report!

Hmm, interesting, can you send .config please?

I need to fix this dependency properly - edac_core needs to have
finished loaded *before* any other EDAC driver loads. Every other order
is wrong.

Yeah, see Johannes' patch.

Btw, calling a driver's probe function from outside the driver is a new
low in driver design. Tztztz...

It's not "a driver's probe function".  There is no driver whose .probe() is
mpc85xx_pci_err_probe() -- the name is historical.

From looking at it, it behaves a lot like a probe function. Irrespective
of what it is or it isn't, calling it from outside a driver which can be
built as a module is a no-no. So I'd appreciate it if someone could test
Johannes' patch on the relevant hardware.

Thanks.

Thanks for pointing the patch out -- it wasn't posted to linuxppc-dev so I
would have missed it otherwise.  I don't need to test it to see that it's
broken -- we can't have two drivers binding to the same device, which is the
reason why the current situation exists.

I recall at the time suggesting that the PCIe controller driver instantiate a
platform device for the EDAC driver to bind to -- it looks like that's what
we'll need to do.

Sounds better. Let me know if there's anything I can help with to get
this sorted out.

Thanks.
