Use kmap_local_page() in binder_alloc.c because kmap() and kmap_atomic() are being deprecated and kmap_local_page is preferred where it is feasible.
With kmap_local_page(), the mapping is per thread, CPU local and not globally visible. Furthermore, the mapping can be acquired from any context, including interrupts.
Fabio M. De Francesco (3): binder: Use memset_page() in binder_alloc_clear_buf() binder: Use kmap_local_page() in binder_alloc_copy_user_to_buffer() binder: Use kmap_local_page() in binder_alloc_get_page()
