"cov" suggests "coverty", and that the symbol is not available in the
kernel suggests that coverty isn't supported.
Maybe some kind of new support has been added, but no one has told the
arm developers, and thus bits needed for it aren't present.
Honestly, I'm not going to worry about it. If someone wishes to
contribute 32-bit arm support, then fine, otherwise I'll just ignore
this.
