Hi all, Today's linux-next merge of the s390 tree got a conflict in: arch/s390/mm/init.c between commit: 30c5e45ee2c53 ("dma-direct: make dma_direct_map_phys() honor DMA_ATTR_CC_SHARED") from the dma-mapping tree and commit: 28b0d6897484a ("s390/pv: Enable SWIOTLB_ANY for s390 PV") from the s390 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. diff --cc arch/s390/mm/init.c index 8d1de5a2e5549,01050a8e7e05a..0000000000000 --- a/arch/s390/mm/init.c +++ b/arch/s390/mm/init.c @@@ -166,7 -151,7 +166,7 @@@ static void __init pv_init(void virtio_set_mem_acc_cb(virtio_require_restricted_mem_acc); /* make sure bounce buffers are shared */ - swiotlb_init(true, SWIOTLB_VERBOSE); - swiotlb_init(true, SWIOTLB_FORCE | SWIOTLB_VERBOSE | SWIOTLB_ANY); ++ swiotlb_init(true, SWIOTLB_VERBOSE | SWIOTLB_ANY); swiotlb_update_mem_attributes(); }
