Subject: [patch 01/21] perfmon2 minimal:  generic hooks

This simple patch adds the perfmon subdirectory to the
top-level Makefile.

It also adds the perfmon2 context pointer to the task
struct. The field points to the perfmon context structure
only when a thread is monitored.

Signed-off-by: Stephane Eranian <eranian@...il.com>
