kaiser: fix build and FIXME in alloc_ldt_struct()
Include linux/kaiser.h instead of asm/kaiser.h to build ldt.c without CONFIG_KAISER. kaiser_add_mapping() does already return an error code, so fix the FIXME. Signed-off-by: Hugh Dickins <hughd@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
