* arch-utils.c, arch-utils.h (default_convert_from_func_ptr_addr):
New function.
* gdbarch.sh (CONVERT_FROM_FUNC_PTR_ADDR): Add.
* gdbarch.c, gdbarch.h: Regenerate.
* valops.c (find_function_addr): Use CONVERT_FROM_FUNC_PTR_ADDR
unconditionally.
* config/rs6000/tm-rs6000.h (CONVERT_FROM_FUNC_PTR_ADDR): Delete
definition.
* config/powerpc/tm-linux.h (CONVERT_FROM_FUNC_PTR_ADDR): Remove
undef.
* rs6000-tdep.c (rs6000_convert_from_func_ptr_addr): Fix comment.
(rs6000_gdbarch_init): Register rs6000_convert_from_func_ptr_addr
if not ELFOSABI_LINUX.
