Subject: [PATCH] Fix segfault on arm machines

Some ARM cpus does not report the cache size or say it is -1 in sysfs.
It has been observed on xgene and thunderx machines.

Fall back to the generic cache size when that happens so we don't
segfault.

Should fix https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=866306
