The generic hardware breakpoint interface provides an abstraction of hardware breakpoints in front of specific arch implementations for both kernel and user side breakpoints. This includes execution breakpoints and read/write breakpoints, also known as "watchpoints". This patch introduces header files containing constants, structure definitions and declaration of functions used by the hardware breakpoint core and x86 specific code. It also introduces an array based storage for the debug-register values in 'struct thread_struct', while modifying all users of debugreg<n> member in the structure.
