hw-breakpoints: introducing generic hardware breakpoint handler interfaces
This patch introduces the generic Hardware Breakpoint interfaces for both user
and kernel space requests.
This core Api handles the hardware breakpoints through new helpers. It
handles the user-space breakpoints and kernel breakpoints in front of
arch implementation.
One can choose kernel wide breakpoints using the following helpers
and passing them a generic struct hw_breakpoint:
- register_kernel_hw_breakpoint()
- unregister_kernel_hw_breakpoint()
- modify_kernel_hw_breakpoint()
On the other side, you can choose per task breakpoints.
- register_user_hw_breakpoint()
- unregister_user_hw_breakpoint()
- modify_user_hw_breakpoint()
