VM86 support, by John Kohl, touched up a bit by me.

/* $NetBSD: sysarch.h,v 1.8 1996/01/08 13:51:44 mycroft Exp $ */
new RCS ID format.

Cleanup and garbage collection; nothing significant. From magnum branch.

*/
#define I386_GET_LDT 0
#define I386_SET_LDT 1
Various changes from John Kohl and me: Map kernel stacks only at unique addresses. Use one TSS per process. Add sysarch calls for modifying IOPL and the I/O permission bitmap. Add a compacting GDT entry allocator, for TSS and LDT selectors. Enable modifying %fs and %gs with PT_SETREGS. Sanitize various bits of code.
