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/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 8e143b90e4d45cca3dc53760d3cfab988bc74571 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_ppc64_defconfig+UP_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc64_defconfig # Added to kconfig CONFIG_SMP=n # yes \n \| make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_ppc64_defconfig+UP_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- oldconfig yes: standard output: Broken pipe # make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_ppc64_defconfig+UP_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/cgroup/cgroup-v1.c: In function 'cgroup1_mount': /kisskb/src/kernel/cgroup/cgroup-v1.c:1263:20: warning: 'root' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/powerpc/kvm/book3s_64_mmu_radix.c: In function '__kvmhv_copy_tofrom_guest_radix': /kisskb/src/arch/powerpc/kvm/book3s_64_mmu_radix.c:75:3: error: 'old_pid' may be used uninitialized in this function [-Werror=uninitialized] cc1: all warnings being treated as errors make[3]: * [/kisskb/src/scripts/Makefile.build:277: arch/powerpc/kvm/book3s_64_mmu_radix.o] Error 1 make[2]: * [/kisskb/src/scripts/Makefile.build:492: arch/powerpc/kvm] Error 2 make[2]: * Waiting for unfinished jobs.... /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] make[1]: * [/kisskb/src/Makefile:1049: arch/powerpc] Error 2 make[1]: * Waiting for unfinished jobs.... /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1434:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/trace/trace_dynevent.c: In function 'create_dyn_event': /kisskb/src/kernel/trace/trace_dynevent.c:89:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/nfsd/nfs4xdr.c: In function 'nfsd4_encode_components_esc': /kisskb/src/fs/nfsd/nfs4xdr.c:2076:9: warning: 'str' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:341:21: note: 'pdeo' was declared here /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] make: * [Makefile:152: sub-make] Error 2 Command 'make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_ppc64_defconfig+UP_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_ppc64_defconfig+UP_powerpc # Build took: 0:01:26.802622
