I think building xe.ko with this include in a header will be racy: any
file that has this include needs to declare the dependency in the
Makefile. I tried a few alternatives to convince the build system to
always execute the generate-rules before anything else, but it failed CI:

I think we will need that before allowing XE_WA() to show up in header
files.
