2) On an mTHP kernel with the latest patchsets (arm64, 64K page size), I
*think* I cannot turn off mTHP. I'm still teasing apart how much of this
is an instrumentation error, and how much is a measurement problem (with
the test suite). And maybe I'm wrong entirely. But the "never" option
doesn't seem to have an effect. Unless the latest version of the testsuite
is doing something new, sigh.

OK, it turns out that the test suite changed over to use hugetlbfs
on this version. So the performance remained high, with or without
THP settings. heh. Please disregard this part. :)


thanks,
