	per CPU present in the sistem, each value being the number of interrupts
	that took place per CPU.

	It can also be used to find out about parameters passed to the init process,
	such as 'BOOT_IMAGE', etc.

	E.g.:
	>>> import procfs
	>>> kcmd = procfs.cmdline()
	>>> print kcmd.keys()
	['LANG', 'BOOT_IMAGE', 'quiet', 'rhgb', 'rd.lvm.lv', 'ro', 'root']
	>>> print kcmd["BOOT_IMAGE"]

	Dictionary with information about CPUs in the system.

	Please refer to 'man procfs(5)' for further information about the
        '/proc/cpuinfo' file, that is the source of the information provided by this
        class. The 'man lscpu(1)' also has information about a program that uses
	the '/proc/cpuinfo' file.

	Using this class one can obtain the number of CPUs in a system:

	  >>> cpus = procfs.cpuinfo()
          >>> print cpus.nr_cpus
          4

	It is also possible to figure out aspects of the CPU topology, such as
	how many CPU physical sockets exists, i.e. groups of CPUs sharing components
	such as CPU memory caches:

	  >>> print len(cpus.sockets)
	  1

	Additionally dictionary with information common to all CPUs in the system is
	available:

	  >>> print cpus["model name"]
          Intel(R) Core(TM) i7-3667U CPU @ 2.00GHz
          >>> print cpus["cache size"]

	The 'perm' member can be used to figure out executable mmaps, i.e. libraries.

	processor instruction pointer addresses to a symbol name in a library.
