Zhangfei Gao acc670dba9 uacce: unmap remaining mmapping from user space ... When uacce parent device module is removed, user app may still keep the mmaped area, which can be accessed unsafely. When rmmod, Parent device driver will call uacce_remove, which unmap all remaining mapping from user space for safety. VM_FAULT_SIGBUS is also reported to user space accordingly.
