Subject: [PATCH] parisc: pci memory bar assignment fails with 64bit kernels on
dino/cujo
References: bnc#1060662
Patch-mainline: v4.12.9
Git-commit: 4098116039911e8870d84c975e2ec22dab65a909
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.
