      llist: clang: introduce member_address_is_nonnull() · beaec533
      Alexander Potapenko authored
      Currently llist_for_each_entry() and llist_for_each_entry_safe() iterate
      until &pos->member != NULL.  But when building the kernel with Clang,
      the compiler assumes &pos->member cannot be NULL if the member's offset
      is greater than 0 (which would be equivalent to the object being
      non-contiguous in memory).  Therefore the loop condition is always true,
      and the loops become infinite.
      
      To work around this, introduce the member_address_is_nonnull() macro,
      which casts object pointer to uintptr_t, thus letting the member pointer
      to be NULL.

      Pull structure randomization updates from Kees Cook:
       "Now that IPC and other changes have landed, enable manual markings for
        randstruct plugin, including the task_struct.
      
        This is the rest of what was staged in -next for the gcc-plugins, and
        comes in three patches, largest first:
      
         - mark "easy" structs with __randomize_layout
      
         - mark task_struct with an optional anonymous struct to isolate the
           __randomize_layout section
      
         - mark structs to opt _out_ of automated marking (which will come
           later)
      
        And, FWIW, this continues to pass allmodconfig (normal and patched to
        enable gcc-plugins) builds of x86_64, i386, arm64, arm, powerpc, and
        s390 for me"
