Oops... two different PATCH 2/3 sent to the Linaro lists. This was the bad one. Please ignore this patch and this thread. Daniel.

The contents of /proc/interrupts is useful to diagnose problems during boot up or when the system becomes unresponsive (or at least it can be if failure is causes by interrupt problems). This command is also seen in out-of-tree debug systems such as Android's FIQ debugger. This change allows the file to be displayed from kdb.
