In timer interrupt handler, we can see the comment that "Signal end of interrupt early to help avoid losing subsequent ticks from long duration handlers".
So, if we want to fix this, shall we remove EOIR writing in GIC IRQ handler (move it to unregistered interrupt branch only) and keep the one in timer interrupt handler, and declare that EOIR should be taken care by each interrupt handler itself, rather than by GIC driver?
Can we use priority drop instead?
