Please pull, thanks.

----------------------------------------------------------------
- Update DM crypt to allocate compound pages if possible.
- Fix DM crypt target's crypt_ctr_cipher_new return value on invalid
AEAD cipher.
- Fix DM flakey testing target's write bio corruption feature to
corrupt the data of a cloned bio instead of the original.
- Add random_read_corrupt and random_write_corrupt features to DM
flakey target.
- Fix ABBA deadlock in DM thin metadata by resetting associated bufio
client rather than destroying and recreating it.
- A couple other small DM thinp cleanups.
- Update DM core to support disabling block core IO stats accounting
and optimize away code that isn't needed if stats are disabled.
- Other small DM core cleanups.
- Improve DM integrity target to not require so much memory on 32 bit
systems. Also only allocate the recalculate buffer as needed (and
increasingly reduce its size on allocation failure).
- Update DM integrity to use %*ph for printing hexdump of a small
buffer. Also update DM integrity documentation.
- Various DM core ioctl interface hardening. Now more careful about
alignment of structures and processing of input passed to the kernel
from userspace. Also disallow the creation of DM devices named
"control", "." or ".."
- Eliminate GFP_NOIO workarounds for __vmalloc and kvmalloc in DM
core's ioctl and bufio code.
