Subject[PATCH v2 0/3] binder: Use kmap_local_page() in binder_alloc.c
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

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 memcpy_{to,from}_page() in binder_alloc_do_buffer_copy()
