        src/sys/arch/i386/i386: gdt.c
        src/sys/arch/i386/include: segments.h
        src/sys/arch/x86/x86: sys_machdep.c

Log Message:
on Xen the GDT has to be updated though HYPERVISOR_update_descriptor().
Export i386/i386/gdt.c:update_descriptor() and use it in x86_set_sdbase(),
as a direct write to the GDT will cause a kernel trap.
Fix PR port-xen/41401.
