+Subject: [PATCH] Fix __libc_fcntl64 prototype in __syscall_fcntl.c
+
+__libc_fcntl64 is a varargs function and should be declared as such.
+Otherwise, the gcc compiler for AVR32, and perhaps other architectures,
+will use the wrong calling convention.

+From: Håvard Skinnemoen <hskinnemoen@atmel.com>
+Date: 1133951618 +0100
+
+Add a linkrelax option to the configure system which will give
+appropriate options to the compiler, assembler and linker to enable
+link-time optimizations.

+Subject: [PATCH] Don't include create_module() for AVR32
+
+The create_module() system call is obsolete in Linux 2.6, so the
+AVR32 kernel doesn't even have it.
+
+Come to think about it, this should be completely unnecessary as the
+create_module function is only a stub when __NR_create_module is
+undefined.

+Subject: [PATCH] ldso: AVR32 startup hack
+
+AVR32 needs to do both PERFORM_BOOTSTRAP_GOT and a full relocation of
+the GOT. I don't quite remember why, but I think it's because some GOT
+entries just need the load address added to them, while the rest need
+the full relocation code.
+
+This patch should be revisited to figure out whether we're processing
+relocations against undefined symbols and whether that's something we
+should be doing...
