Release 2.1.21:

  Compatibility issues with 2.0:

    insmod --   the support is supposed to be there, but it is still
		relatively untested.

    genksyms -- produces identical results except in a couple of 
		pathological cases in which the original genksyms
		parser gets very confused.  This affects a few 
		symbols such as

			register_sysctl_table
			unregister_sysctl_table
			tq_timer
			tq_immediate
			tq_scheduler

  insmod, rmmod, lsmod, and ksyms are separate programs again.
