Hi all, Today's linux-next merge of the kvm-x86 tree got a conflict in: include/uapi/linux/kvm.h between commit: bcac0477277e ("KVM: x86: move x86-specific structs to uapi/asm/kvm.h") from the kvm tree and commits: 01a871852b11 ("KVM: x86/xen: allow shared_info to be mapped by fixed HVA") 3a0c9c41959d ("KVM: x86/xen: allow vcpu_info to be mapped by fixed HVA") from the kvm-x86 tree. I fixed it up (I used the former version of this file and applied the following fix up patch) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts.
