There are addition fixes for sparc in #1700 which still need to be cleaned up and merged. It would be helpful if you created a branch with all the fixes needed.

[marku89]

Right, its horrible to jump from patch to patch ... I check it out when its running with the #1700

[marku89]

So now i have a working branch on sparc ! https://github.com/marku89/spl , https://github.com/marku89/zfs
I will clean up it a little bit so that my changes not harm the normal arches.

[behlendorf]

That would be great. When you're happy with it please go ahead and open a pull request so we can review it.

[marku89]

Done , pull request for zfs #1938 and for spl openzfs/spl#317
