Russell King 6d75fe7ed2 ARM: spectre-v2: warn about incorrect context switching functions 
Commit c44f366ea7c85e1be27d08f2f0880f4120698125 upstream.

Warn at error level if the context switching function is not what we
are expecting.  This can happen with big.Little systems, which we
currently do not support.
