I would go for arch_kentry_{test/is_}stalled() since this would clearly
hint at the stage stall bit.

Name could be confusing since you also have
arch_kentry_set_lockdep(). arch_kentry_test_hardirq() instead?

arch_kentry_{set_}stall{ed}()

I would pick arch_kentry_set_hardirq() to better match the general
naming scheme you have been using for these helpers, fixing the original
misnomer in the same move (the idea conveyed by the original name was
too vague/broadly scoped already).

Please split this into separate commits (arm: irq_pipeline, arm64:
irq_pipeline and genirq: irq_pipeline).
