Subject: [PATCH V9 06/20] asm-generic: compat: Cleanup duplicate definitions
From: Guo Ren <guoren@...ux.alibaba.com>
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.
