This patch set attempts to move ia64/ppc64/parisc64 C function
pointer ABI details out of printk() to arch code. Function dereference
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.
...> *** A BIG NOTE ***
I don't own ia64/ppc64/parisc64 hardware, so the patches are not
tested. Sorry about that!
I need to check what is BPF symbol lookup and do we need to
do any dereference there.
