Summary0016514: Update to Centos 7.7 / Arch ppc64le / Problem with nvidia driver
Description
today I updated a CentOS 7.6 ppc64le machine to CentOS 7.7. After reboot to the
new kernel (4.18.0-80.7.2.el7.ppc64le) dkms could not build the nvidia-module.

Error-message from dkms:

Compiler version check failed:

The major and minor number of the compiler used to
compile the kernel:

gcc version 8.3.1 20190311 (Red Hat 8.3.1-3) (GCC)

does not match the compiler used here:

cc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)


Output of /proc/version with new kernel running is:
Linux version 4.18.0-80.7.2.el7.ppc64le (mockbuild@ppc64le-01.bsys.centos.org)
(gcc version 8.3.1 20190311 (Red Hat 8.3.1-3) (GCC)) #1 SMP Thu Sep 12 15:45:05
UTC 2019

Problem seams to be:

The kernel was compiled with gcc-version 8.3.1 and installed is gcc 4.8.5. All
previous kernels were compiled with gcc 4.8.5. See:

#cat /usr/src/kernels/*/include/generated/compile.h |grep LINUX_COMPILER
