+Subject: [PATCH] aarch64: fix BTI in bsaes assembly code
+
+In Arm systems where BTI is enabled but the Crypto extensions are not (more
+likely in FVPs than in real hardware), the bit-sliced assembler code will
+be used. However, this wasn't annotated with BTI instructions when BTI was
+enabled, so the moment libssl jumps into this code it (correctly) aborts.
+
+Solve this by adding the missing BTI landing pads.
+
+Upstream-Status: Submitted [https://github.com/openssl/openssl/pull/23982]
