What's the issue here? I'm not sure I understand your comment here - this is annotated as SYM_FUNC_ which is the annotation for things that look like normal C functions. > > .align 11 > > -ENTRY(__bp_harden_hyp_vecs_start) > > +SYM_CODE_START_NOALIGN(__bp_harden_hyp_vecs) > > +SYM_INNER_LABEL(__bp_harden_hyp_vecs_start, SYM_L_GLOBAL) > Why isn't SYM_CODE_START_NOALIGN enough? And what is the rational for The _start and _end labels that were there before are explicitly referenced by code, removing them would break the build. > the _NOALIGN, btw? I'd expect an alignment of 2kB to be more than enough. So that the explicit .align above takes effect rather than anything the macro decides to do, I'm trying to err on the side of caution here.
