Problem Details: virt_to_phys() doesn't work on systems with IOMMU enabled, which have non-identity physical-to-IOVA mappings. It leads to IO_PAGE_FAULTs like this: [IO_PAGE_FAULT domain=0x0023 address=0x1cce00000 flags=0x0020] And no association to the AP can be established. This patch changes that to dma_map_sing...

Problem Details: The ppace array is not freed if one of the init_acl_state() calls inside parse_dacl() fails. At the moment the function may fail only due to the memory allocation errors so it's highly unlikely in this case but nevertheless a fix is needed.
