[Bug kprobes/2064] New: Support pagepoint probes

[jkenisto at us dot ibm dot com]

It has been requested that we support "pagepoint" probes.  Such a probe is
analogous to a watchpoint probe; but with a pagepoint probe, neither the number
of concurrent probes nor the size of the probed area is limited by the CPU's
debug-register architecture.

Pagepoint probes would presumably be implemented by fussing the permission bits
on the probed page(s) and hooking the page-fault handler (or exploiting the
existing kprobes hook).
