Hi, here is a patch-set to rename iommu_param to dev_iommu and establish it as a struct for generic per-device iommu-data. Also move the iommu_fwspec pointer from struct device into dev_iommu to have less iommu-related pointers in struct device. The bigger part of this patch-set moves the iommu_priv pointer from struct iommu_fwspec to dev_iommu, making is usable for iommu-drivers which do not

Hi, I've been setting ocfs2 up on a two node 'cluster', using gnbd (network block device) to talk to a shared disk on a third node. build/install was very straightforward and I have the file system mounted on both nodes just fine. However, I've been rather disappointed by the performance: With just one node actively using the fs (but with the other mounted) I'm finding that

From: Thierry Reding <treding at nvidia.com> Hi Ben, here's a revised subset of the patches I had sent out a couple of weeks ago. I've reworked the BAR2 accesses in the way that you had suggested, which at least for GP10B turned out to be fairly trivial to do. I have not looked in detail at this for GV11B yet, but a cursory look showed that BAR2 is accessed in more places, so the
