Last round of s390x fixes for 2.5:
- The bios should be built for the first z machine, so that newer instructions don't creep in. - Silence annoying message when running make check. - Fix a problem with the pci iommu exposed by recent changes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJWXWF+AAoJEN7Pa5PG8C+vGboP/3HPOv/khkfJI4EVwheXg+av tSCOxizp0oPg02kDfOvmBl0czVL7UQN8cR6sLcEvXADJIvHqiryX8PA+1FOVpZwx m0ZJTb3Vt2biPbhgMf9l0d+xOAo1EQSSxeys84Z22xwNA7wCGZQN9ysBmyjCBiKh Oq/9D5qLGlmLb4Oz3Cb25Tw0Qhj4g7xdoNJOvfYycK8eDPxGhhSBKSm8QwKhOZY/ o+SB4Mj/86P8UrWa037DMpYY893RRBX9YfJTEQrNG8el47rXeU8PMo79AYFtuj78 Ps71pxMnb/UpNq5vy5Oz6qyFsqJtzfuFhDbLYHIanw1zBW8tKhHDFGd56Gz0syWe E8wyB6Q4hP/xYX2ozT+z+uq8/W7BGY33vk1e5jU6WWaoBypVt0gPZ4KM+g5F86JH ixsZFpJtijLg0CUmhubdFeiiH2j9xA99ICdqlcwdoMpK8GwPPza5tJ6LxJglU+nq 4FOaEdkx6B3c4crwvWcWLFU3lZuQ3TVm5HcapAcq2tqO0jw7WP1gDm6c2KGrof6H OdPYnPARH5OboEMzcFsEVCjmY5SGhmk39FqYpa92lFfhD+jKgMqXTWR3n96HWTAu rNGhacPibiyohLrm0wVO1rk8kajhNK18dQA1+gYVO6DU9O0ODgS1Oozbc83PfwE7 EIiGY4Hc9y3wB/aPTrco =xIKz -----END PGP SIGNATURE----- Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20151201' into staging Last round of s390x fixes for 2.5: - The bios should be built for the first z machine, so that newer instructions don't creep in. - Silence annoying message when running make check. - Fix a problem with the pci iommu exposed by recent changes. # gpg: Signature made Tue 01 Dec 2015 08:59:42 GMT using RSA key ID C6F02FAF # gpg: Good signature from "Cornelia Huck <huckc@linux.vnet.ibm.com>" # gpg: aka "Cornelia Huck <cornelia.huck@de.ibm.com>" * remotes/cohuck/tags/s390x-20151201: s390x/pci: fix up IOMMU size s390x: no deprecation warning while testing pc-bios/s390-ccw: rebuild image pc-bios/s390-ccw: build for z900 Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
