-/* The correct solution is for _dl_vdso_vsym to return the address of the OPD
-   for the kernel VDSO function.  That address would then be stored in the
-   __vdso_* variables and returned as the result of the IFUNC resolver function.
-   Yet, the kernel does not contain any OPD entries for the VDSO functions
-   (incomplete implementation).  However, PLT relocations for IFUNCs still expect
-   the address of an OPD to be returned from the IFUNC resolver function (since
-   PLT entries on PPC64 are just copies of OPDs).  The solution for now is to
-   create an artificial static OPD for each VDSO function returned by a resolver
-   function.  The TOC value is set to a non-zero value to avoid triggering lazy
-   symbol resolution via .glink0/.plt0 for a zero TOC (requires thread-safe PLT
-   sequences) when the dynamic linker isn't prepared for it e.g. RTLD_NOW.  None
-   of the kernel VDSO routines use the TOC or AUX values so any non-zero value
-   will work.  Note that function pointer comparisons will not use this artificial
-   static OPD since those are resolved via ADDR64 relocations and will point at
-   the non-IFUNC default OPD for the symbol.  Lastly, because the IFUNC relocations
-   are processed immediately at startup the resolver functions and this code need
-   not be thread-safe, but if the caller writes to a PLT slot it must do so in a
-   thread-safe manner with all the required barriers.  */
