-Subject: [PATCH 3/3] aarch64: correct comment describing BTI
-
-The comment is incorrect, BTI is enabled per mapping via mprotect with
-PROT_BTI flag set, not per-process. When the loader loads the library,
-if the GNU Notes section is missing this, PROT_BTI will not be enabled
-for that mapping, but is independent of other mappings.
