   @masayuki2009 yes, I used the same code.
   The main issue that this PR attempts to solve is that `INTENABLE` of one CPU can't be accessed by the other CPU, so we keep track of the one that enabled an interrupt and when disabling it we use an IPI if we are not running on the correct CPU.
   
   I wanted to do some refactoring to separate the pause request from the IRQ request but it's not as simple as I thought it would be.
