+Subject: [PATCH 1/2] linux: avoid using CLOCK_SGI_CYCLE
+
+The call clock_gettime(CLOCK_SGI_CYCLE, &t) from function getticks() fails with EINVAL.
+See : http://elixir.free-electrons.com/linux/latest/source/include/uapi/linux/time.h#L62 - "The driver implementing this got removed. The clock ID is kept as a place holder. Do not reuse!"
