[PATCH] add debug trace to CMA

[Benjamin Gaignard]

Hello,

The goal of those two patches is to add debug and trace capabilities to CMA
on going development.

The first patch allow to dump CMA bitmap status by a simple "cat
/sys/kernel/debug/cma" command line.

The second add events trace points that can be used for performance and/or
log with trace tools:
- to enable it "echo 1 > /sys/kernel/debug/tracing/events/cma/enable"
- to get the log "cat /sys/kernel/debug/tracing/events/trace"

Regards,

Benjamin
