[PATCH 4.12 02/41] parisc: pci memory bar assignment fails with 64bit kernels on dino/cujo

Show all headers | View raw

4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Bogendoerfer <tsbogend@alpha.franken.de>

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.
