Subject: [PATCH] Let optimized stringops override default ones
The default, slow stringops must be archived _before_ the optimized
stringops if there is to be any point doing the optimizations in the
first place.

The first argument to getrusage is of type __rusage_who_t, not int.
This patch fixes that.

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.

Subject: [PATCH] Fix broken __libc_open declaration in open64.c
__libc_open is a vararg function and should therefore be declared as
such. Fixes bug #4190.

Subject: [PATCH] Make linkrelax configurable
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The create_module() system call is obsolete in Linux 2.6, so the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...
