	This little package implements two ways of turning off/on
	the level 1 cache (i.e. onboard CPU) found on i486 and
	higher chips. 

	This has to be done from within the kernel, since you
	can't get high enough access to do it from user space,
	even with iopl().

	Method one is to use a syscall, and then a small (assembly)
	program to call the syscall with an on or off argument.
	A kernel patch is required to implement the new syscall.
	The syscall patch and the l1on/l1off programs are in the
	syscall directory.

	Method two is to use a module. Modules run at kernel privilege
	level, and so we can simply do the job from the init_module
	routine and then remove the module to reclaim our memory back.
	This doesn't require a kernel patch but it does require module
	support to be compiled into the kernel. The l1off and l1on
	modules can be found in the modules directory.
