Author: pfg Date: Sun Jan 29 00:45:52 2017 New Revision: 312942 URL: https://svnweb.freebsd.org/changeset/base/312942
Log: Remove GCC's __nonnull() attribute definition. While GCC's __nonnull__ attribute is generally useful to prevent misuse of some functions it also tends to do rather dangerous "optimizations". Now that we have replaced (r312934) all such uses with the clang nullability qualifiers, the GCC attribute is unnecessary. Remove the definition completely to prevent its use in system's headers.
