---Problem Description---
depmod does not handle .TOC symbol on powerpc platforms
 
Contact Information = Douglas Miller <dougmill at linux.vnet.ibm.com> 
 
---uname output---
Linux p8le03 4.4.0-38-generic #57-Ubuntu SMP Tue Sep 6 15:40:06 UTC 2016 ppc64le ppc64le ppc64le GNU/Linux
 
Machine Type = other 
 
---Debugger---
A debugger is not configured
 
---Steps to Reproduce---
 Compile kernel, during modules_install target the messages appear. PPC64 modules have a .TOC symbol which is required. It may be the only symbol with a period in the name, and so tools that restrict symbols based on a pattern may neglect to include .TOC.
 
Userspace tool common name: depmod 
 
The userspace tool has the following bit modes: 64 

Userspace rpm: libkmod2:ppc64el

Userspace tool obtained from project website:  na

 I was doing a build of upstream origin/master on Ubuntu 16.04.2 fresh install and still getting these messages. In the "make modules_install" output I see:

...
