----------------------------------------------------------------
- Fix DM ioctl interface to avoid INT_MAX overflow warnings from kvmalloc by limiting the number of targets and parameter size area.

- Fix DM stats to avoid INT_MAX overflow warnings from kvmalloc by limiting the number of entries supported.

- Fix DM writecache to support mapping devices larger than 1 TiB by switching from using kvmalloc_array to vmalloc_array -- which avoids INT_MAX overflow in kvmalloc_node and associated warnings.

- Remove the (ab)use of tasklets from both the DM crypt and verity targets. They will be converted to use BH workqueue in future.
