Blackfin Exception Scratch Register
└─>CYCLES
In linux kernel since version 2.6.24 (release Date: 2008-01-24)  
Use the CYCLES register in the Blackfin exception handler
as a stack scratch register. This means you cannot
safely use the CYCLES performance registers on a Blackfin
board at anytime, but you can debug the system with a JTAG
ICE and use the NMI.
