[Linaro-mm-sig] [PATCH] add debug trace to CMA

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
