Hello,

This patch simply makes the implicit "struct target_ops" parameter to 
convert_from_func_ptr_addr explicit (it also makes it pure multi-arch). 
  It doesn't try to update any actual architecture code so I think this 
is pretty save and will commit in a few hours (after my cross builds 
finish).

By doing this, the new architecture bfd_entry_point previous proposed in:

[ppc64-linux] gdbarch hook to find true execution entry point
http://sources.redhat.com/ml/gdb-patches/2003-06/msg00362.html
[ppc64-linux]: correctly find a BFD's code entry point address
http://sources.redhat.com/ml/gdb-patches/2003-06/msg00437.html

made entirely redundant.  ya!

I'll follow this up with patches that fill in the dots needed to make 
PPC64 GDB actually work.

Andrew
