Vegard Nossum 915eed20e4 um: Support kcov ... This adds support for kcov to UML. There is a small problem where UML will randomly segfault during boot; this is because current_thread_info() occasionally returns an invalid (non-NULL) pointer and we try to dereference it in __sanitizer_cov_trace_pc(). I consider this a bug in UML itself and this patch merely exposes it.
