I just tested a feature specific to HardenedBSD: force calls to
malloc(9) to include the M_ZERO flag (the hardening.kmalloc_zero
sysctl tunable.) I have that tunable set to 1 in loader.conf(5) on
both laptops.

It appears this commit conflicts with the feature in general. I'll see
what I can do on HardenedBSD's side to better align our feature with
this commit.

Sorry for the noise.

For reference, here are the two HardenedBSD commits that provide the
feature:

1.
https://git.hardenedbsd.org/hardenedbsd/HardenedBSD/-/commit/c3ee4601417ae1daa7a0a3adc9259bf0739a8d55
2.
