Because ELF standard supports only page sizes up to 64K, then you should
use patched binutils for building applications to be run with the 256KB-
page sized kernel. The patch for binutils is rather trivial, and may
look as follows:
--- binutils/bfd/elf32-ppc.c.orig
+++ binutils/bfd/elf32-ppc.c

-#define ELF_MAXPAGESIZE                0x10000
+#define ELF_MAXPAGESIZE                0x40000
You don't have to patch it, it's enough to pass -zmax-page-size=3D0x40000
to the linker.
 Thanks for pointing this. I guess, the -zmax-page-size option is new=20
to binutils 2.17.50.0.10. Right?

 I'll remove the STDBINUTILS config option from this patch then, and=20
correspondingly update the description.

 Regards, Yuri
