Author: marius Date: Sun Oct 17 13:41:12 2010 New Revision: 213974 URL: http://svn.freebsd.org/changeset/base/213974 Log: MFC: r213578 In the replacement text of the __bswapN_const() macros cast the argument to the expected type so they work like the corresponding __bswapN_var() functions and the compiler doesn't complain when arguments of different width are passed.
