There are 7 64bit architectures that support Linux COMPAT mode to run 32bit applications. A lot of definitions are duplicate: - COMPAT_USER_HZ - COMPAT_RLIM_INFINITY - COMPAT_OFF_T_MAX - __compat_uid_t, __compat_uid_t - compat_dev_t - compat_ipc_pid_t - struct compat_flock - struct compat_flock64 - struct compat_statfs - struct compat_ipc64_perm, compat_semid64_ds, compat_msqid64_ds, compat_shmid64_ds Cleanup duplicate definitions and merge them into asm-generic.
