[PULL] Fix ioctls on 32bit/64bit userspace/kernel, for 4.10

[David Sterba <dsterba@suse.com>]

Hi,

could you please merge this single-patch pull request, for 4.10 still?  There
are quite a few patches on top of v4.10-rc7 so this IMHO does not look like
look too bad even late in the release cycle. Though it's a fix for an uncommon
usecase of 32bit userspace on 64bit kernel, it fixes basically operation of the
ioctls. Thanks.

The following changes since commit 57b59ed2e5b91e958843609c7884794e29e6c4cb:

  Btrfs: remove ->{get, set}_acl() from btrfs_dir_ro_inode_operations (2017-01-26 15:48:56 -0800)
