 # Kernel tags:
 # Tags files are built in the top-level directory for each architecture,
 # with a makefile listing the architecture-dependent files, etc.  The list
 # of common files is in ./Make.tags.inc.  Links to the correct tags file
 # are placed in each source directory.  We need to have links to tags files
 # from the generic directories that are relative to the machine type, even
 # via remote mounts; therefore we use symlinks to $SYSTAGS, which points at
 # ${SYSDIR}/${MACHINE_ARCH}/tags.
