The existing wording is correct:

 "the kernel will make sure that ... that many HPTEs are invalid"

The existing wording is correct:

 "the kernel will make sure that ... that many HPTEs are invalid"

Maybe it would be better as "that the number of invalid HPTEs is the same
as the invalid count"?

as the invalid count"?

That doesn't read quite right, I think because if the number of invalid
HPTEs doesn't match the invalid count, the code will invalidate HPTEs so
that the number matches.

So maybe:

  When the invalid count is non-zero in the header written to the stream,
  the kernel will make sure that number of HPTEs are invalid, or
  invalidate them if not.
