Thanks!

This could be Valgrind not knowing where the memory came from.  Only if your
libdrm library is built with Valgrind devel files present in the system, it
will annotate the memory it returns from kernel for Valgrind.

On Ubuntu 14.10, the necessary files come with "valgrind" package, but libdrm
needs to be (re-)build after that is installed.

Another issue is that for Valgrind backtraces to be useful, Mesa debug symbols
are needed, so that we can see where (which source file/line) the Valgrind
warnings are coming from.

Could you fix those issues and attach updated Valgrind output?
