hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8JVJ3 CVE: NA
----------------------------------------
One of the ILP32 patchset rename 'compat_user_mode' and 'compat_thumb_mode' to 'a32_user_mode' and 'a32_user_mode'. But these two macros are used in some opensource userspace application. To keep compatibility, we redefine these two macros.
