+# CONFIG_ARM64_BTI:
+# 
+# Branch Target Identification (part of the ARMv8.5 Extensions)
+# provides a mechanism to limit the set of locations to which computed
+# branch instructions such as BR or BLR can jump.
+# 
+# To make use of BTI on CPUs that support it, say Y.
+# 
+# BTI is intended to provide complementary protection to other control
+# flow integrity protection mechanisms, such as the Pointer
+# authentication mechanism provided as part of the ARMv8.3 Extensions.
+# For this reason, it does not make sense to enable this option without
+# also enabling support for pointer authentication.  Thus, when
+# enabling this option you should also select ARM64_PTR_AUTH=y.
+# 
+# Userspace binaries must also be specifically compiled to make use of
+# this mechanism.  If you say N here or the hardware does not support
+# BTI, such binaries can still run, but you get no additional
+# enforcement of branch destinations.
+# 
+# Symbol: ARM64_BTI [=y]
+# Type  : bool
+# Defined at arch/arm64/Kconfig:1594
+#   Prompt: Branch Target Identification support

+#     -> Kernel Features
