I had a look at the patchset now, it looked mostly good.

I fixed most of the trivial issues I noticed, and pushed with that.

Please have a look at the comments I made, in particular, the weird

+        mov             x8, #32
+        str             x8, [sp, #-80]!

in patch 5/6 is left untouched as is. Feel free to propose follow-up 
patches to fix that. I also didn't try to tweak the scheduling of e.g. the 
subs instructions.
