Change 100227 by jhb at jhb_mutex on 2006/06/28 19:33:59

	Axe the stackgap macros!  There's some scary i386-specific code under
	#if 0 to try to use the stackgap to set the LDT via sysarch().  If
	anyone wants to revive that they can come up with a suitable kern_foo()
	or i386_foo() API to use instead.
