      iommu: spapr_tce: Disable compile testing to fix build on book3s_32 config · 9dd124b6
      Krzysztof Kozlowski authored
      Although SPAPR_TCE_IOMMU itself can be compile tested on certain PowerPC
      configurations, its presence makes arch/powerpc/kvm/Makefile to select
      modules which do not build in such configuration.
      
      The arch/powerpc/kvm/ modules use kvm_arch.spapr_tce_tables which exists
      only with CONFIG_PPC_BOOK3S_64.  However these modules are selected when
      COMPILE_TEST and SPAPR_TCE_IOMMU are chosen leading to build failures:

      iommu/mediatek: Fix MTK_IOMMU dependencies · d1dcb725
      Geert Uytterhoeven authored
      If NO_DMA=y (e.g. Sun-3 all{mod,yes}-config):
      
          drivers/iommu/dma-iommu.o: In function `iommu_dma_mmap':
          dma-iommu.c:(.text+0x836): undefined reference to `dma_pgprot'
      
      IOMMU_DMA must not be selected, unless HAS_DMA=y.
      
      Hence fix this by making MTK_IOMMU depend on HAS_DMA.
      While at it, remove the dependency on ARM || ARM64, as that is already
      implied by the dependency on ARCH_MEDIATEK.

      iommu: Fix the memory leak in dev_iommu_free() · 5375e874
      Kevin Hao authored
      In iommu_probe_device(), we would invoke dev_iommu_free() to free the
      dev->iommu after the ->add_device() returns failure. But after commit
      72acd9df ("iommu: Move iommu_fwspec to struct dev_iommu"), we also
      need to free the iommu_fwspec before the dev->iommu is freed. This fixes
      the following memory leak reported by kmemleak:
        unreferenced object 0xffff000bc836c700 (size 128):
          comm "swapper/0", pid 1, jiffies 4294896304 (age 782.120s)

      firmware_loader: revert removal of the fw_fallback_config export · 5a357703
      Luis Chamberlain authored
      Christoph's patch removed two unsused exported symbols, however, one
      symbol is used by the firmware_loader itself.  If CONFIG_FW_LOADER=m so
      the firmware_loader is modular but CONFIG_FW_LOADER_USER_HELPER=y we fail
      the build at mostpost.
      
      ERROR: modpost: "fw_fallback_config" [drivers/base/firmware_loader/firmware_class.ko] undefined!
      
      This happens because the variable fw_fallback_config is built into the
      kernel if CONFIG_FW_LOADER_USER_HELPER=y always, so we need to grant
      access to the firmware loader module by exporting it.
      
      Revert only one hunk from his patch.
