Michael Holzheu 237d6e6884 s390/hypfs: Use get_free_page() instead of kmalloc to ensure page alignment ... Since commit d86bd1bece ("mm/slub: support left redzone") it is no longer guaranteed that kmalloc(PAGE_SIZE) returns page aligned memory. After the above commit we get an error for diag224 because aligned memory is required. This leads to the following user visible error: # mount none -t s390_hypfs /sys/hypervisor/ mount: unknown filesystem type 's390_hypfs' # dmesg | grep hypfs hypfs.cccfb8: The hardware system does not provide all functions required by hypfs hypfs.7a79f0: Initialization of hypfs failed with rc=-61 Fix this problem and use get_free_page() instead of kmalloc() to get correctly aligned memory.
