Adding test that:
- detects the number of watch/break-points,
skip test if any is missing
- detects PERF_EVENT_IOC_MODIFY_ATTRIBUTES ioctl,
skip test if it's missing
- detects if watchpoints and breakpoints share
same slots
- create all possible watchpoints on cpu 0
- change one of it to breakpoint
- in case wp and bp do not share slots,
we create another watchpoint to ensure
the slot accounting is correct

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
