Hi all,
Changes since 20160311:
The vfs tree gained a conflict against Linus' tree. I also applied a
patch for a known runtime bug.
The tip tree gained a conflict against the mips tree.
The aio tree still had a build failure so I removed several commits
from it. It also gained a conflict against the vfs tree.
Non-merge commits (relative to Linus' tree): 11202
8646 files changed, 426680 insertions(+), 211740 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 (with
CONFIG_BUILD_DOCSRC=n) 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 x86_64 allnoconfig,
powerpc allnoconfig (32 and 64 bit), ppc44x_defconfig, allyesconfig
(this fails its final link) and pseries_le_defconfig and i386, sparc
and sparc64 defconfig.
Below is a summary of the state of the merge.
I am currently merging 231 trees (counting Linus' and 35 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,
Stephen Rothwell

To give people an idea what to expect in the merge window, here are my current

This may be due to this qemu bug: http://patchwork.ozlabs.org/patch/585237/
> arm64:nosmp:defconfig
Since 4b3dc9679cf7 ("arm64: force CONFIG_SMP=y and remove redundant #ifdefs"),
this may just be testing the smp case again - unless your qemu config is
different too.

Thanks - this looks like a mine of information!

You are right, with that patch applied to qemu it looks better, meaning
the image now crashes due to the failing i2c initialization.

Only difference is that it disables SMP, or at least tries to. I'll want to
keep it around for earlier kernels, though.
Thanks,

These are all an i2c crash, which I assume is the one you mention above.
> powerpc:nosmp:ppc64_e5500_defconfig
This seems to be caused by:
arch/powerpc/sysdev/fsl_rcpm.c:32:2: error: implicit declaration of function 'get_hard_smp_processor_id' [-Werror=implicit-function-declaration]
ie. that driver doesn't build for SMP=n.

I bisected this failure to commit bb11cff327e54 ("MIPS: Make smp CMP, CPS and MT
use the new generic IPI functions". Bisect log is attached.

If necessary I can repeat the bisect for those. Please let me know.

I run the tests with only a single CPU core enabled. Maybe that causes

Look in rootfs/*mips* for qemu scripts and root file systems.
The SMP tests all fail, so it should not matter which one you pick.
I use my own version of qemu, but for mips standard qemu 2.5.0 should
work fine (I don't have any mips specific changes in my version).

I ran another qemu test (this time on mainline) with "-smp 2", but the only
difference is that the image now gets stuck even earlier.
Also, I ran another set of bisects, this time with both mips and mips64
on mainline (after your patch landed), with the same results.

OK thanks for the info. The offending commit just enables using quite a
few of the newly added code before that. So the problem could be in any
of the newly added code.
Unfortunately I can only look at this during my limited time in the
evening and I have to setup my system to compile and run this, so I
won't be able to get to the bottom of this as fast as I'd like to.

OK I was up and running faster than I thought I would be. Can you
confirm that you're hitting a BUG_ON() in mips_smp_ipi_init()?
What I see is that BUG_ON() is hit because we couldn't find an ipidomain
to allocate the ipis from. The reason of whih is that the qemu malta
machine doesn't have a GIC though the config is compiled with GIC on.
Also if I remember correctly qemu malta doesn't really support SMP. I
think that was the reason I never ran this on qemu.
I'm not sure what's the best way forward here. I can add a check to
verify gic_present inside this function and return early. Patch attached.
Ralf, thoughts?

Most likely, but mips is one of the qemu emulations which simply hang if there is a crash,
without a log message, and I have not been able to figure out a command line that gives me
the actual crash log.

With your patch I get
WARNING: CPU: 0 PID: 1 at arch/mips/kernel/smp.c:251 mips_smp_ipi_init+0x3c/0x1b0()
and the boot continues.
If Ralf accepts it, feel free to add
Tested-by: Guenter Roeck <[email protected]>
though I'll probably adjust my configuration to drop GIC from it (if that is possible).
Thanks a lot for looking into this!

The reason of whih is that the qemu malta machine doesn't have a GIC though the config is compiled with GIC on. Also if I remember correctly qemu malta doesn't really support SMP. I think that was the reason I never ran this on qemu.
Turns out MIPS_GIC is auto-selected by MIPS_MALTA, so I can not just unconfigure it.
Too bad. That means if your patch isn't accepted, I'll have to drop the mips
SMP build runtime tests, unless you have a better idea.
