Andy Lutomirski 2e549b2ee0 x86/vdso: Fix vDSO build if a retpoline is emitted ... Currently, if the vDSO ends up containing an indirect branch or call, GCC will emit the "external thunk" style of retpoline, and it will fail to link. Fix it by building the vDSO with inline retpoline thunks. I haven't seen any reports of this triggering on an unpatched kernel.
