Merge two commits that had dependencies on other 5.11 trees (the block
and the irq trees respectively).

 - We reverted a megaraid_sas change in 5.10 due to missing block
   layer plumbing. Now that this is in place, reinstate the change.

 - The hisi_sas driver had a dependency on a driver core irq change
   that went in through Thomas' tree.
