Linux did the same thing 18 years ago and their reasons for the change are similar to ours - https://github.com/torvalds/linux/commit/7d12e78 Most interrupt handlers (i.e. IRQ handlers) never used the register state reference anywhere so there's simply no need of passing it around. I didn't measure the performance boost but surely this change can't make things worse anyway.
