            Bug ID: 89460
           Summary: wrong size in struct drm_mode_get_connector
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/intel
          Assignee: chris at chris-wilson.co.uk

        QA Contact: intel-gfx-bugs at lists.freedesktop.org

Hi everybody,
 I'm trying to run a 32bits Linux distribution with a 64 bits Linux kernel and
I have problems with Intel driver for xorg.

By tracing the problem and then searching in Google I found this conversation:
  http://comments.gmane.org/gmane.linux.kernel.stable/67503

It seems that due to differences in the size of struct drm_mode_get_connector
is neccesary to add a "__u32 pad" at the end of the structure. And this was
added to the kernel.

But if you look in libdrm-2.4.58/include/drm/drm_mode.h the
"drm_mode_get_connector" struct haven't got any padding.

Is this a bug?
Is possible to run a 32 bits linux distribution with a 64 bits Linux kernel? or
is it an impossible dream?

Best regards!
