[PATCH] uml: consolidate modify_ldt
*) Reorganize the two cases of sys_modify_ldt to share all the reasonably common code. *) Avoid memory allocation when unneeded (i.e. when we are writing and the passed buffer size is known), thus not returning ENOMEM (which isn't allowed for this syscall, even if there is no strict "specification"). *) Add copy_{from,to}_user to modify_ldt for TT mode.
