Pull device mapper updates from Mike Snitzer:

- Eliminate a couple indirect calls from bio-based DM core.

- Fix DM to allow reads that exceed readahead limits by setting
io_pages in the backing_dev_info.

- A couple code cleanups in request-based DM.

- Fix various DM targets to check for device sector overflow if
CONFIG_LBDAF is not set.

- Use u64 instead of sector_t to store iv_offset in DM crypt; sector_t
isn't large enough on 32bit when CONFIG_LBDAF is not set.

- Performance fixes to DM's kcopyd and the snapshot target focused on
limiting memory use and workqueue stalls.

- Fix typos in the integrity and writecache targets.

- Log which algorithm is used for dm-crypt's encryption and
dm-integrity's hashing.

- Fix false -EBUSY errors in DM raid target's handling of check/repair
messages.

- Fix DM flakey target's corrupt_bio_byte feature to reliably corrupt
the Nth byte in a bio's payload.

dm: Check for device sector overflow if CONFIG_LBDAF is not set

dm: Check for device sector overflow if CONFIG_LBDAF is not set

Reference to a device in device-mapper table contains offset in sectors.

If the sector_t is 32bit integer (CONFIG_LBDAF is not set), then
several device-mapper targets can overflow this offset and validity
check is then performed on a wrong offset and a wrong table is activated.

See for example (on 32bit without CONFIG_LBDAF) this overflow:

# dmsetup create test --table "0 2048 linear /dev/sdg 4294967297"
# dmsetup table test
0 2048 linear 8:96 1

This patch adds explicit check for overflow if the offset is sector_t type.

y2038: convert more syscalls

Here is another set of system call changes to prepare the change over to
64-bit time_t. As before, the strategy is to change system calls that
take a 'struct timespec' argument over to 'struct __kernel_timespec',
which for now is defined to be the same but will get redefined to use a
64-bit time_t argument once we are ready to modify the system call tables.

The major change from previous patches is that the plan is no longer
to directly use the 'compat' system calls for providing compatibility
with the existing 32-bit time_t based entry points. Instead, we rename
the compat code to something that makes more sense on 32-bit architectures,
e.g. compat_timespec becomes old_timespec32.

With the renamed types in place, change over the 'stat' and 'utimes'
families of system calls, sched_rr_get_interval, recvmmsg and
rt_sigtimedwait. Another series for poll, select and io_pgetevents is
currently being tested.

dm delay: add flush as a third class of IO

Add a new class for dm-delay that delays flush requests. Previously,
flushes were delayed as writes, but it caused problems if the user
needed to create a device with one or a few slow sectors for the purpose
of testing - all flushes would be forwarded to this device and delayed,
and that skews the test results. Fix this by allowing to select 0 delay
for flushes.
