SubjectRe: [PATCH v2 09/15] admin-guide/hw-vuln: Correct prctl() argument description

Technically, the constants referenced in the documentation are still
defined in prctl.h, and there are BUILD_BUG_ON() checks to ensure they
match their PIDTYPE_ equivalents. I would presume these should be left
in as it is technically a defined interface and user code could break.

Presumably you mean PIDTYPE_ here? Otherwise looks good and in
retrospect this is probably what should have been done in the first place.
