commit bd3eaf83ef1b4954b6c0e7ba8bbdd29b2cd4a833
Author: Cristian Morales Vega <cristian at samknows.com>
Date:   Tue Sep 23 13:17:25 2014 +0100

    Do not define unimplemented functions
    
    e.g. fminf() is not implemented, only fmin(), but both are defined.

commit 3f6cd5063abe21992552a17116f5489cbd2021e3
Author: Waldemar Brodkorb <wbx at openadk.org>
Date:   Fri Sep 26 11:46:22 2014 +0200

    cris: remove call to HIDDEN_JUMPTARGET
    
    errno_location is no longer hidden, so remove the call
    to the macro, like done for sparc recently.

commit 4b03b0db9d9eded088f3c70b4127447f1097de79
Author: Waldemar Brodkorb <wbx at openadk.org>
Date:   Fri Sep 26 11:37:02 2014 +0200

    cris: do not include asm/elf.h
    
    elf.h is not exported by the Linux kernel, do not include
    it here. Done like in other architectures.
