Hi all,
Today's linux-next merge of the kvm tree got a conflict in:
include/uapi/linux/kvm.h
between commit:
9bb4a6f38fd4 ("KVM: PPC: Book3S HV: Add KVM_CAP_PPC_RPT_INVALIDATE capability")
from the powerpc tree and commits:
644f706719f0 ("KVM: x86: hyper-v: Introduce KVM_CAP_HYPERV_ENFORCE_CPUID")
6dba94035203 ("KVM: x86: Introduce KVM_GET_SREGS2 / KVM_SET_SREGS2")
0dbb11230437 ("KVM: X86: Introduce KVM_HC_MAP_GPA_RANGE hypercall")
from the kvm tree.
I fixed it up (see below) 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.
What are the dependencies of these KVM patches on patches from the bare
metal trees, and can you guys *please* start using topic branches?
I've been asking you for literally years, but this is the first time I
remember that Linus will have to resolve conflicts in uAPI changes and
it is *not* acceptable.
Please drop the patches at
https://www.spinics.net/lists/kvm-ppc/msg18666.html from the powerpc
tree, and merge them through either the kvm-powerpc or kvm trees.
