The only generic interface to execute asynchronously in the BH context is
tasklet; however, it's marked deprecated and has some design flaws. To
replace tasklets, BH workqueue support was recently added. A BH workqueue behaves similarly to regular workqueues except that the queued work items
are executed in the BH context.

This patch converts drivers/infiniband/* from tasklet to BH workqueue.

Based on the work done by Tejun Heo <tj@xxxxxxxxxx>
Branch: https://git.kernel.org/pub/scm/linux/kernel/git/tj/wq.git for-6.10

Note: Not tested. Please test/review.

Applied and tested the s390 AP bus and zcrypt part of the patch.
Works fine, a sniff test did not show any problems.
Thanks for your work.
