The pointer to the next STI font is actually a signed 32-bit offset. With this change the 64-bit kernel will correctly subract the (signed 32-bit) offset instead of adding a (unsigned 32-bit) offset. It has no effect on 32-bit kernels. This fixes the stifb driver with a 64-bit kernel on qemu.

commit 8a32aa17c1cd48df1ddaa78e45abcb8c7a2220d6 upstream.

The pointer to the next STI font is actually a signed 32-bit
offset. With this change the 64-bit kernel will correctly subract
the (signed 32-bit) offset instead of adding a (unsigned 32-bit)
offset. It has no effect on 32-bit kernels.

This fixes the stifb driver with a 64-bit kernel on qemu.

This is necessary on 64-bit only machines (e.g. C8000 workstation) which otherwise won't show the STI text console with HP graphic cards like Visualize-FX5/FX10/FXe. Note that when calling 32-bit code from a 64-bit kernel one needs to copy contents on the CPU stack from high memory down below the 4GB limit.

Implement the fbdev helper fb_get_options() on top. Will allows to handle the kernel parameter in DRM without fbdev dependencies. Note that __video_get_options() has the meaning of its return value inverted compared to fb_get_options(). The new helper returns true if the adapter has been enabled, and false otherwise. There is the ofonly parameter, which disables output for non-OF-based framebuffers. It is only for offb and looks like a workaround. The actual purpose it not clear to me.
