FreeBSD has an existing CACHE_LINE_SIZE parameter as a platform-specific define.
```
# /usr/include/machine/param.h
/*
* CACHE_LINE_SIZE is the compile-time maximum cache line size for an
* architecture. It should be used with appropriate caution.
*/
#define CACHE_LINE_SHIFT 6
#define CACHE_LINE_SIZE (1 << CACHE_LINE_SHIFT)
```
Remove the use of relative paths. A header at foo/bar.h could be included by
files under foo/ with "bar.h", but would be included everywhere else as
"foo/bar.h". Adjust so that every include references such a header with the
latter form.
