Pull misc fixes from Miguel Ojeda:
 "A trivial patch for auxdisplay:

   - Replace HTTP links with HTTPS ones (Alexander A. Klimov)

  The usual clang-format trivial update:

   - Update with the latest for_each macro list (Miguel Ojeda)

  And Luc requested me to pick a sparse fix on my queue, so here it goes
  along with other two trivial Compiler Attributes ones (also from Luc).

   - sparse: use static inline for __chk_{user,io}_ptr() (Luc Van
     Oostenryck)

   - Compiler Attributes: fix comment concerning GCC 4.6 (Luc Van
     Oostenryck)

   - Compiler Attributes: remove comment about sparse not supporting
     __has_attribute (Luc Van Oostenryck)"
