12 * When using in-kernel BTI we need to ensure that PCS-conformant
13 * assembly functions have suitable annotations. Override
14 * SYM_FUNC_START to insert a BTI landing pad at the start of
15 * everything, the override is done unconditionally so we're more
16 * likely to notice any drift from the overridden definitions.
