New Revision: 277078
URL: https://svnweb.freebsd.org/changeset/base/277078
Log:
Remove duplicate copies of trivial getcontextx.c
Only i386 and amd64 provide a non-trivial __getcontextx(). Use a common
trivial implementation in gen/ for other architectures, rather than
copying the file to each MD subdirectory.
