| H A D | kasan_sw_tags.S | 742a15b1 Tue Dec 14 09:27:14 CST 2021 Mark Brown <broonie@kernel.org> arm64: Use BTI C directly and unconditionally
Now we have a macro for BTI C that looks like a regular instruction change
all the users of the current BTI_C macro to just emit a BTI C directly and
remove the macro.
This does mean that we now unconditionally BTI annotate all assembly
functions, meaning that they are worse in this respect than code generated
by the compiler. The overhead should be minimal for implementations with a
reasonable HINT implementation.
