Hi all, Today's linux-next merge of the akpm-current tree got a conflict in: arch/arm64/kvm/mmu.c between commit: 70fb2fa12176 ("KVM: arm/arm64: Release kvm->mmu_lock in loop to prevent starvation") from the kvm-arm tree and commit: 72ff958aa971 ("arm64: add support for folded p4d page tables") from the akpm-current 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. -- Cheers, Stephen Rothwell diff --cc arch/arm64/kvm/mmu.c index ddf85bf21897,534d9798c3cb..000000000000 --- a/arch/arm64/kvm/mmu.c +++ b/arch/arm64/kvm/mmu.c @@@ -421,10 -469,7 +469,10 @@@ static void stage2_flush_memslot(struc do { next = stage2_pgd_addr_end(kvm, addr, end); if (!stage2_pgd_none(kvm, *pgd)) - stage2_flush_puds(kvm, pgd, addr, next); + stage2_flush_p4ds(kvm, pgd, addr, next); + + if (next != end) + cond_resched_lock(&kvm->mmu_lock); } while (pgd++, addr = next, addr != end); }
