[PATCH v2 25/33] include/linux/resctrl.h: Define fork and exit functions in a new header file

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@xxxxxxxxx>

A new header file is created in include/linux/resctrl.h. It contains
defintions of rdtgroup_fork and rdtgroup_exit for x86. The functions
are empty for other architectures.
