Please check attachment file, which I downloaded from [1] and modified under the BZ comment 1. The trigger method is also in comment 1, I copy here: ./defragfs_test.sh -d

This introduces vringh, which are generic accessors for virtio rings (host side). There's a host-side implementation in vhost, but it assumes that the rings are in userspace, and is tied to the vhost implementation. I have patches to adapt it to use vringh, but I'm pushing this in the next merge window for Sjur, who has CAIF patches which need it. This also includes a test program in

fb_do_apertures_overlap is returning wrong value when one aperture is completely whithin the other. Add generic ranges_overlap macro (probably kernel.h candidate) and use it here.

We don't want vga16fb to mess with hardware initialized by other driver. Detect it and refuse to load. It fixes nouveau interrupt storm on some machines.

This fixes remaining sparse warnings in vringh and mic by using virtio 1.0 compliant wrappers. This also needs by get_user patches to avoid getting warnings from these calls. Tested by running vringh_test. Rusty, I prefer fixing all these warnings for 3.19, any objections? Michael S. Tsirkin (3): vringh: 64 bit features vringh: initial virtio 1.0 support mic/host: initial virtio 1.0

From: Matt Fleming <matt.fleming at linux.intel.com> This series fixes some bugs and switches the elflink branch to be entirely ELF modules. It applies on top of, http://syslinux.zytor.com/archives/2011-April/016369.html The deletions in the diff stat below are mainly from deleting com32/elflink/modules (finally!). Now there should be no duplicate code because we don't need COM32 and
