VFIO had to work around that in the # past and I included a patch to remove it (acked by Alex Williamson) # # - Patches to unmodularize a couple of IOMMU drivers that would never # work as modules anyway. # # - Work to unify the the iommu-related pointers in 'struct device' into # one pointer. This work is not finished yet, but will probably be in # the next cycle. # # - NUMA aware allocation in iommu-dma code # # - Support for r8a774a1 and r8a774c0 in the Renesas IOMMU driver # # - Scalable mode support for the Intel VT-d driver # # - PM runtime improvements for the ARM-SMMU driver # # - Support for the QCOM-SMMUv2 IOMMU hardware from Qualcom # # - Various smaller fixes and improvements # # * tag 'iommu-updates-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (78 commits) # iommu: Check for iommu_ops == NULL in iommu_probe_device() # ACPI/IORT: Don't call iommu_ops->add_device directly # iommu/of: Don't call iommu_ops->add_device directly # iommu: Consolitate ->add/remove_device() calls # iommu/sysfs: Rename iommu_release_device() # dmaengine: sh: rcar-dmac: Use device_iommu_mapped() # xhci: Use device_iommu_mapped() # powerpc/iommu: Use device_iommu_mapped() # ACPI/IORT: Use device_iommu_mapped() # iommu/of: Use device_iommu_mapped() # driver core: Introduce device_iommu_mapped() function # iommu/tegra: Use helper functions to access dev->iommu_fwspec # iommu/qcom: Use helper functions to access dev->iommu_fwspec # iommu/of: Use helper functions to access dev->iommu_fwspec # iommu/mediatek: Use helper functions to access dev->iommu_fwspec # iommu/ipmmu-vmsa: Use helper functions to access dev->iommu_fwspec # iommu/dma: Use helper functions to access dev->iommu_fwspec # iommu/arm-smmu: Use helper functions to access dev->iommu_fwspec # ACPI/IORT: Use helper functions to access dev->iommu_fwspec # iommu: Introduce wrappers around dev->iommu_fwspec # ... # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 8e143b90e4d45cca3dc53760d3cfab988bc74571 # < make -s -j 8 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 allmodconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # yes \n \| make -s -j 8 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 oldconfig yes: standard output: Broken pipe # make -s -j 8 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/um/os-Linux/umid.c: In function 'is_umdir_used': /kisskb/src/arch/um/os-Linux/umid.c:138:2: warning: ISO C90 forbids variable length array 'file' [-Wvla] char file[strlen(uml_dir) + UMID_LEN + sizeof("/pid\0")];
