The macros are defined backwards.
This affects the following compat syscalls:
- compat_sys_truncate64()
- compat_sys_ftruncate64()
- compat_sys_fallocate()
- compat_sys_sync_file_range()
- compat_sys_fadvise64_64()
- compat_sys_readahead()
- compat_sys_pread64()
- compat_sys_pwrite64()
Fixes: 43d5de2b67 ("asm-generic: compat: Support BE for long long args in 32-bit ABIs")
