After doing a fresh install of Qubes 3.2 on a Skylake system, I noticed 
that 'xl dmesg' was reporting "mwait-idle: does not run on family 6 model 
94".  As I mentioned above, a patch is available to address this.  Since 
then, the above patch was committed to xen.git 
(4c6cd64519f9bc270a7278128c94e4b66e3d2077).

There are also commits for mwait-idle updates to Kaby Lake 
(1008063e1cd15257875b9db18eede710077adea5) and Skylake Xeon 
(9062fd6bfa5211398582780d89d655cff9f9ed8c).

While you are at it, you might want to pull in a couple of subsequent 
Skylake-related commits: 5a211704e8813c4890c8ce8dc4189d1dfb35ecd0 
("mwait-idle: prevent SKL-H boot failure when C8+C9+C10 enabled") 
and 372ad59dd0e7a3df0bd46ec3c8b934d739eb07b5 ("mwait-idle: add a missing 
__init annotation").

There is another Skylake-related commit unrelated to mwait-idle 
(c52319642bb9069436d4aec75361049f5fac63ed), but I don't know if this is 
actually likely to cause any issues.
