[PATCH 4.9 03/27] parisc: pci memory bar assignment fails with 64bit kernels on dino/cujo
From: Greg Kroah-Hartman
Date: Tue Aug 22 2017 - 15:27:03 EST
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Bogendoerfer <tsbogend@xxxxxxxxxxxxxxxx>
commit 4098116039911e8870d84c975e2ec22dab65a909 upstream.
For 64bit kernels the lmmio_space_offset of the host bridge window
isn't set correctly on systems with dino/cujo PCI host bridges.
This leads to not assigned memory bars and failing drivers, which
need to use these bars.
