Frederic Weisbecker 91f73f90d9 tracing/markers: make markers select tracepoints
Sometimes it happens that KConfig dependencies are not handled
like in the following scenario:

- config A
   bool

- config B
   bool
   depends on A

- config C
   bool
   select B

If one selects C, then it will select B without checking its
dependency to A, if A hasn't been selected elsewhere, it will
result in a build failure.

This is what happens on the following build error:

 kernel/built-in.o: In function `marker_update_probe_range':
 (.text+0x52f64): undefined reference to `tracepoint_probe_register_noupdate'
 kernel/built-in.o: In function `marker_update_probe_range':
 (.text+0x52f74): undefined reference to `tracepoint_probe_unregister_noupdate'
 kernel/built-in.o: In function `marker_update_probe_range':
 (.text+0x52fb9): undefined reference to `tracepoint_probe_unregister_noupdate'
 kernel/built-in.o: In function `marker_update_probes':
 marker.c:(.text+0x530ba): undefined reference to `tracepoint_probe_update_all'

CONFIG_KVM_TRACE will select CONFIG_MARKER, but the latter
depends on CONFIG_TRACEPOINTS which will not be selected.
