Hi Greg,
Is the reason Sudip gave you for the question of "why" sufficient ?
This patch is very important for the driver running in the X86 platform.
Without this patch, many SM750 graphic chip customers complain the Ubuntu OS
can't run well. When they install the OS, the screen will be full of garbage in
xorg.
Ubuntu 16.04.2 LTS and above will enable sm750 staging driver by default. We
need this patch. Thanks.
Best Regards,
Teddy Wang

Did a quick research into "why".
The patch d8801e4df91e ("x86/PCI: Set IORESOURCE_ROM_SHADOW only for the
default VGA device") has started setting IORESOURCE_ROM_SHADOW in flags for a
default VGA device and that is being done only for x86.
And so, we will need that #ifdef to check IORESOURCE_ROM_SHADOW as that needs
to be checked only for a x86 and not for other arch.
