Commit c7f419f584 moved softmmu-only files out of the root
directory, but forgot to move the trace events, which should
no longer be generated to "trace-root.h". Fix that by adding
softmmu/trace-events.

Dang!  I'd like to have this in 5.1 if at all possible.

scripts/cleanup-trace-events.pl finds these (and corrects them in-place,
which is not what we want here).  It finds a few more.  I'll look more
closely and report back.

Congratulation, you just found the first job you'll add to our GitLab CI

cleanup-trace-events.pl is not fit for use in CI; see the list of
funnies in "[PATCH 4/4] trace-events: Fix attribution of trace points to
source".  Perhaps it could be sufficiently improved.

Does this matter at all for usage of tracepoints?

Hi Paolo, I tested both with and without the fix,
the events seem to be generated anyway.

Using simple trace backend, simple smoke test tracing the memory_region_ops_read from softmmu/memory.c

Thanks,

Markus said on IRC it is a false alarm, can wait 5.2 :)

I retracted quickly on IRC, but neglected to post.  This can wait for
5.2.
