Hi Greg,
I looked at the 4 warnings I received from your emails, and they all
appear in i386 architecture.
I don't want to support 32-bit kernel and I don't intend to support it.
Can we just specify in kconfig that we don't support it, and then you
won't get these warnings ?
I initially set in kconfig to support only x86_64, and you told me
(and you were right) not to limit to that. But I do think I would like
to disable the driver on i386.

Thanks,
Oded
