         This patch set attempts to move ia64/ppc64/parisc64 C function

code now checks if a pointer belongs to a .opd ELF section and dereferences
that pointer only if it does. The kernel and modules have their own .opd
sections that's why I use two different ARCH functions: for kernel and
for module pointer dereference.

         I don't own ia64/ppc64/parisc64 hardware, so the patches are not
         tested. Sorry about that!

I just now tested your patch series successfully on parisc64.

You may add to the whole series:
Tested-by: Helge Deller <deller@gmx.de> # parisc64

  

Another note:
         I need to check what is BPF symbol lookup and do we need to
         do any dereference there.

Not relevant for parisc, since we don't support it yet.
