Bug#862522: cuda 9.0 RC available

[Lumin]

Hi,

Brief compiler results
---------------------------------------

A quick test of cuda 9.0 RC on unstable (with GCC-7 as the default)

clang-3.{8,9}, Broken build by GCC-7 headers? see the build examples below
clang-4.0, not supported
gcc-{5,6}, OK
gcc-7, not supported, failure when bypassing the #error from host_config.h

I tried to rebuild my package src:caffe-contrib with clang-3.8 with
cuda-{8.0,9.0~RC} and it is likely that GCC-7 headers breaks
the clang build of the prorobuf file. The error is the same as
the vectorAdd example below.

Conclusion:
  1. (may be bug) GCC-7 headers may break clang-3.{8,9} build.
  2. A simple hack doesn't make nvcc work with GCC-7.
  3. GCC-6 is likely working with CUDA9. But I didn't test it on
      any real world application (caffe is still not prepared for 9.0).

      @doko How long do you plan to keep GCC-6 in the archive?


WIP cuda 9.0 packaging
------------------------------------------

The debian directory (based on 8.0.44-4) for 9.0 RC is attached.
Changes:
nvidia-cuda-toolkit (9.0.103-1) UNRELEASED; urgency=medium

  * New upstream release 9.0~RC (Aug 2017).
  * SOVERSION bump: 8.0 => 9.0, rename all library packages.
  * Remove libnppi9.0 which is deprecated by upstream.
  * Refresh symbols control files.
  * Use dh_missing --list-missing instead of dh_install --list-missing.
  * Update installation paths.
  * Temprarily remove symbols for libcublas
  * [FIXME] Temporarily disable all patches.

Notes,
 1. Nvidia Fermi architecture (compute_20) is deprecated.
 2. The driver version shipped by 9.0~RC is 384.59
