Sorry, I meant to say that luksOpen worked with the patches.  I simply
copy&pasted the wrong line.

Well, it seems to fix the problem and according to the thread on lkml
the lack of flush_anon_page() on ARM is associated with some
corruption.  At least FUSE doesn't work on ARM without those patches,
so it seems likely that luksOpen is also affected.
