Hi Stephen, updating s390 tree for linux-next today I had to include a change which is already present in kvm tree: 1a82f6ab2365 ("s390/uaccess: Add copy_from/to_user_key functions") it will get conflicts in arch/s390/lib/uaccess.c with the changes from s390 tree now: 432b1cc78e98 ("s390/uaccess: Add copy_from/to_user_key functions") 4efd417f298b ("s390: raise minimum supported machine generation to z10") 731efc9613ee ("s390: convert ".insn" encoding to instruction names") please simply take the version from s390 tree (removing bunch of code from arch/s390/lib/uaccess.c file). So that with regular order of merges (s390/for-next comes before kvm/next) kvm/next merge will not bring any new changes to arch/s390/lib/uaccess.c cat Next/merge.log | grep -i 'Merge .*\(kvm\|s390\)' | grep -v arm $ git merge -m Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git s390-fixes/fixes $ git merge -m Merge branch 'master' of git://git.kernel.org/pub/scm/virt/kvm/kvm.git kvm-fixes/master $ git merge -m Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux.git kvms390-fixes/master $ git merge -m Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git s390/for-next $ git merge -m Merge branch 'next' of git://git.kernel.org/pub/scm/virt/kvm/kvm.git kvm/next $ git merge -m Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux.git kvms390/next Thank you
