The complaint is due to SMAP validation; objtool will scream if there's a CALL in between STAC/CLAC. The thinking is that since they open a security window, we want tight code between them. We also very much don't want tracing and other funnies to happen there. As such, any CALL is dis-allowed. This weird option is having us upgrade quite a few 'inline' to '__always_inline'.
