It's really not necessary to limit E820_X_MAX to 128 in the non-EFI case. This commit drops E820_X_MAX's dependency on CONFIG_EFI, so that E820_X_MAX is always at least slightly larger than E820MAX. The real motivation behind this is actually to prevent some issues in the Xen kernel, where the XENMEM_machine_memory_map hypercall can produce an e820 map larger than 128 entries, even on systems where the original e820 table was quite a bit smaller than that, depending on how many IOAPICs are installed on the system.

Variable err is initialized with 0. As a result, the return value may be 0 even if get_zeroed_page() fails to allocate memory. This patch fixes the bug, initializing err with "-ENOMEM". Signed-off-by:

Variable rc is reset in the loop, and its value will be non-negative during the second and after repeat of the loop. If it fails to allocate memory then, it may return a non-negative integer, which indicates no error. This patch fixes the bug, assigning "-ENOMEM" to rc when kzalloc() or alloc_page() returns NULL, and removing the initialization of rc outside of the loop. Signed-off-by:

The function xen_guest_init is using __alloc_percpu with an alignment which are not power of two. However, the percpu allocator never supported alignments which are not power of two and has always behaved incorectly in thise case. Commit 3ca45a46 "percpu: ensure requested alignment is power of two" introduced a check which trigger a warning [1] when booting linux-next on Xen. But in reality this bug was always present. This can be fixed by replacing the call to __alloc_percpu with alloc_percpu. The latter will use an alignment which are a power of two.

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:

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.
