On ARM (32 bits and 64 bits), the double-word is 8-bytes aligned. This will result on different structure from Xen and Linux repositories. As Linux is using __packed__ attribute, it must have a 4-bytes padding before each "id" field. This change breaks guest block support with older kernel. IMHO, it's acceptable because Xen on ARM is still on Tech Preview and the hypercall ABI is not yet freezed. Only one architecture (x86_32) doesn't have 64-bit ABI for the block interface. Don't add padding if Linux is compiled for this architecture.

On arm64 the dma_map_ops implementation is based on the swiotlb. swiotlb-xen, used by default in dom0 on Xen, is also based on the swiotlb. Avoid calling into the default arm64 dma_map_ops functions from xen_dma_map_page, xen_dma_unmap_page, xen_dma_sync_single_for_cpu, and xen_dma_sync_single_for_device otherwise we end up calling into the swiotlb twice. When arm64 gets a non-swiotlb based implementation of dma_map_ops, we'll probably have to reintroduce dma_map_ops calls in page-coherent.h.

The PCI MMCONFIG area is usually reserved via the E820 so the Xen hypervisor is aware of these regions. But they can also be enumerated in the ACPI DSDT which means the hypervisor won't know of them until the initial domain informs it of via PHYSDEVOP_pci_mmcfg_reserved.

Pull parisc fixes from Helge Deller: "This patchset includes a bugfix to prevent a kernel crash when memory in page zero is accessed by the kernel itself, e.g. via probe_kernel_read(). Furthermore we now export flush_cache_page() which is needed (indirectly) by the lustre filesystem. The other patches remove unused functions and optimizes the page fault handler to only evaluate variables if needed, which again protects against possible kernel crashes" * 'parisc-3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: let probe_kernel_read() capture access to page zero parisc: optimize variable initialization in do_page_fault parisc: fix interruption handler to respect pagefault_disable() parisc: mark parisc_terminate() noreturn and cold. parisc: remove unused syscall_ipi() function. parisc: kill SMP single function call interrupt parisc: Export flush_cache_page() (needed by lustre)
