Build Failure on linux-next on Power8 machine

Build Failure on linux-next on Power8 machine

[vrbagal1]

Greetings!!!


I am observing a build failure on linux-next kernel.

Machine: Power8
Platform: PowerNV(Baremetal)
Git Tree: 
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git

Below is the build error.

14:20:48 make[1]: *** [kernel/umh.o] Error 1

Which defconfig do you use, or can you give your .config ?

Unfortunately I lost it. I  only have complete fail logs. Will that be 
helpful?

We really need the .config, or at least some idea of which config it is.

We also really need to know which exact revision you're building.
linux-next is updated every day.

Today's build results are here:

  http://kisskb.ellerman.id.au/kisskb/head/14032/


I don't see any fails that look similar to yours. So perhaps you're
using a different compiler or something. That's another detail you
should tell us, the exact compiler version :)
