Patch-mainline: v4.16-rc3
Subject: x86/headers/UAPI: Use __u64 instead of u64 in <uapi/asm/hyperv.h>
Git-commit: 894266466aa74a226e58e23975118ff6231dd2e4
References: bsc#1107207

... since u64 has a hidden header dependency that was not there before
using it (i.e. it breaks our VMM build).

Also, __u64 is the right way to expose data types through UAPI.
