Having just seen this among the commits having gone in recently -
was it considered to make this a common function? The
implementations currently differ, but I'm not sure I see why that
needs to be. With x86's vcpu_kick_softirq() handler doing nothing
I could see the ARM implementation be suitable for x86, just like
I could see the x86 implementation be suitable for ARM.
