| Subject: parisc: pci memory bar assignment fails with 64bit kernels on |
| dino/cujo |
| |
| 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. |
