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

Posted by Fabio M. De Francesco 4 years ago

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()
