+----------------------------------------------------------------------
+These days most developers use `git send-email` instead of regular

+
+If you are new to git then send your first patch to yourself. Save it

+then review the changelog with `git log`. When that works then send

-This interface depends on CONFIG_ARCH_MEMORY_PROBE.

-CONFIG_ARCH_MEMORY_PROBE is supported on powerpc only. On x86, this config
