Add a new probe event for the hardware breakpoint called wprobe-event.
This wprobe allows user to trace (watch) the memory access at the
specified memory address.

s/the memory/the kernel memory/

The new syntax is;

 w[:[GROUP/]EVENT] [r|w|rw]@[ADDR|SYM][:SIZE] [FETCH_ARGs]

User also can use $addr to fetch the accessed address and $value to fetch
the accessed memory value (shorthand for '+0($addr)'). No other variables
are supported.

This seems limited to kernel addresses only? Should not also userspace
addresses be supported?
