From: Thomas Bogendoerfer Date: Sat, 12 Aug 2017 21:36:47 +0000 (+0200) Subject: parisc: pci memory bar assignment fails with 64bit kernels on dino/cujo X-Git-Tag: v3.2.95~111 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=02b1ca57b42bd07c90e45ab507fadec0c808bb1d;p=thirdparty%2Fkernel%2Fstable.git 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.
