Greg K-H,

Would you be able to pick up this entire patchset via driver-core; I
figure that tree is the most appropriate to receive any core ISA bus
driver changes (unless you see a more fitting path to take).

If possible, I'd like this patchset to find its way into one of the
coming release candidates in order to resolve the regression mentioned
in the cover letter: as of 4.7-rc1, the drivers which switched to
utilize the ISA bus driver are now restricted to X86_32 despite being
allowed in X86_64 in the 4.6 release.

Thanks,

William Breathitt Gray
