The most interesting one is an atomicity update in the GIC set_affinity callback, which could race against the update of another 3 adjacent interrupts (I broke it 4 years ago, and nobody noticed...). The other bug is a nice GICv4.1 sleep-in-atomic found by Zenghui. The rest fixes a couple of typos. Please pull, M.
