Hi all, attached is a patch that enables using hardware crypto accelerators available through OpenSSL library for SSH operations. Especially in ssh/sshd it can bring a significant speed improvement. OTOH if no crypto engine is available, nothing bad happens and default software crypto routines are used. This patch is used in SUSE Linux OpenSSH package and proved to work (at least it didn't

So far the DRM GPUVA manager offers common infrastructure to track GPU VA allocations and mappings, generically connect GPU VA mappings to their backing buffers and perform more complex mapping operations on the GPU VA space. However, there are more design patterns commonly used by drivers, which can potentially be generalized in order to make the DRM GPUVA manager represent a basic GPU-VM

From: Jason Gunthorpe <jgg at mellanox.com> 8 of the mmu_notifier using drivers (i915_gem, radeon_mn, umem_odp, hfi1, scif_dma, vhost, gntdev, hmm) drivers are using a common pattern where they only use invalidate_range_start/end and immediately check the invalidating range against some driver data structure to tell if the driver is interested. Half of them use an interval_tree, the others
