>Environment:
	using kzip'ed kernels

>Description:
	The bootstrap loader starts the kernel and passes one argument
	"howto" to the kernel. This is also true when using kzip'ed kernels,
	but in "/sys/i386/boot/kzipboot/head.S" the function "_boot" is called
	which puts another int on the stack, so the parameter "howto" of the
	function "boot" refers to the wrong address.

>How-To-Repeat:
	Just boot a kzip'ed kernel.

>Fix:
	Add a dummy-parameter to the function "boot", like:

		void boot (int dummy, int howto)
