+	  Build the kernel with support for Indirect Branch Tracking, a
+	  hardware support course-grain forward-edge Control Flow Integrity
+	  protection. It enforces that all indirect calls must land on
+	  an ENDBR instruction, as such, the compiler will instrument the
+	  code with them to make this happen.
+
+	  In addition to building the kernel with IBT, seal all functions that
+	  are not indirect call targets, avoiding them ever becomming one.
+
+	  This requires LTO like objtool runs and will slow down the build. It
+	  does significantly reduce the number of ENDBR instructions in the
+	  kernel image.
