Here I would recommend two things:
- introduce an empty PC_COMPAT_2_9 macro
- in the PC_COMPAT_2_8 macro being modified, add a trailing backslash
after HW_COMPAT_2_8
Both of these aim at keeping up the current pattern; namely, for the
most recent machine type, a PC_COMPAT macro should exist (even if empty
/ unused), plus each PC_COMPAT macro should be extensible by plain
appending (hence the final trailing backslash).
Functionally the above hunk is good of course, so I'll leave it to you
whether you actually want to address my comments.
The rest looks fine; I should be able to rebase my broadcast SMI (v5)
stuff to this.
Changed or unchanged:
