Move counter set specific controls and functions to the asm/cpu_mcf.h header file containg all counter facility support definitions. Also adapt few variable names and header file includes. No functional changes. Signed-off-by: Hendrik Brueckner <brueckner@linux.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
