commit bd3eaf83ef1b4954b6c0e7ba8bbdd29b2cd4a833
Author: Cristian Morales Vega <cristian(a)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.
Signed-off-by: Cristian Morales Vega <cristian(a)samknows.com>
commit 3f6cd5063abe21992552a17116f5489cbd2021e3
Author: Waldemar Brodkorb <wbx(a)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(a)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.
