This version of the patch produces a compile error for me about 
|add_interrupt_randomness

[PATCH] hyperv: Fix compilation issue with 4.4.19-rt27

[Juerg Haefliger]

Fix a compilation issue introduced by upstream commit
4b44f2d18a330565227a7348844493c59366171e

The upstream commit exports the symbol add_interrupt_randomness()
which is now being used in the Hyper-V driver. The RT patch adds another
argument to that function so its usage in the Hyper-V driver needs to
be fixed.

This patch should be merged with:
patches/0216-random-Make-it-work-on-rt.patch
commit 20985550b01a21ba00a587d17d7c26da61e01acc random: Make it work on rt

I guess I should have run "make allmodconfig" before posting. Just
didn't have the time. :-/

Thanks for the patch. I'm currently working to get my mainline work
finished (that's taking up my resources). I'll work to include this
patch either tomorrow, or it will have to wait for next week, as it's a
US holiday weekend.
