use target_mmap() to allocate idt, gdt and ldt (Kirill A. Shutemov).
env->*dt.base should fit target address space, so we should use target_mmap to allocate them. Signed-off-by: Kirill A. Shutemov <kirill@shutemov.name> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5666 c046a42c-6fe2-441c-8c8c-71466251a162
