ARM and arm64 Xen ports share a number of headers, leading to packaging issues when these headers needs to be exported, as it breaks the reasonable requirement that an architecture port has self-contained headers. Fix the issue by moving the 5 header files to include/xen/arm, and keep local placeholders to include the relevant files. Signed-off-by:

Commit 9c17d965 ("xen/gntdev: Grant maps should not be subject to NUMA balancing") set VM_IO flag to prevent grant maps from being subjected to NUMA balancing. It was discovered recently that this flag causes get_user_pages() to always fail with -EFAULT. check_vma_flags __get_user_pages __get_user_pages_locked __get_user_pages_unlocked get_user_pages_fast iov_iter_get_pages dio_refill_pages do_direct_IO do_blockdev_direct_IO do_blockdev_direct_IO ext4_direct_IO_read generic_file_read_iter aio_run_iocb (which can happen if guest's vdisk has direct-io-safe option). To avoid this let's use VM_MIXEDMAP flag instead --- it prevents NUMA balancing just as VM_IO does and has no effect on check_vma_flags(). Cc: stable@vger.kernel.org Reported-by:

Mounting proc in user namespace containers fails if the xenbus filesystem is mounted on /proc/xen because this directory fails the "permanently empty" test. proc_create_mount_point() exists specifically to create such mountpoints in proc but is currently proc-internal. Export this interface to modules, then use it in xenbus when creating /proc/xen. Signed-off-by:

The connect function prints an unintialized error code after an earlier initialization was removed: drivers/net/xen-netback/xenbus.c: In function 'connect': drivers/net/xen-netback/xenbus.c:938:3: error: 'err' may be used uninitialized in this function [-Werror=maybe-uninitialized] This prints it as -EINVAL instead, which seems to be the most appropriate error code. Before the patch that caused the warning, this would print a positive number returned by vsscanf() instead, which is also wrong. We probably don't need a backport though, as fixing the warning here should be sufficient. Fixes: f95842e7 ("xen: make use of xenbus_read_unsigned() in xen-netback") Fixes: 8d3d53b3 ("xen-netback: Add support for multiple queues") Signed-off-by:

dw_pcie_iatu_unroll_enabled() reads a dbi_base register. Reading any dbi_base register before pp->ops->host_init has been called causes "imprecise external abort" on platforms like ARTPEC-6, where the PCIe module is disabled at boot and first enabled in pp->ops->host_init. Move dw_pcie_iatu_unroll_enabled() to dw_pcie_setup_rc(), since it is after pp->ops->host_init, but before pp->iatu_unroll_enabled is actually used.

Pull parisc updates from Helge Deller: "The first three patches are trivial and add some required KERN_CONT, ignore the new pkey syscalls on parisc and use the LINUX_GATEWAY_ADDR define instead of hardcoded values. The two patches from Dave Anglin are important. The first one avoids trashing the sr2 and sr3 space registers in the Light-weight syscall path. Especially the usage of sr3 is critical since it may get trashed by the interrupt handler. The second patch is even more important and tagged for stable series. It protects one critical section in the syscall entry path by disabling local interrupts. Without disabling interrupts, the sr7 space register may not be in sync with the current stack setup and thus an incoming hardware interrupt may destroy memory in random userspace areas" * 'parisc-4.9-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Ignore the pkey system calls for now parisc: Use LINUX_GATEWAY_ADDR define instead of hardcoded value parisc: Ensure consistent state when switching to kernel stack at syscall entry parisc: Avoid trashing sr2 and sr3 in LWS code parisc: use KERN_CONT when printing device inventory
