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.
