No, they are not relevant because none of them can be reproduced on a
v5.12+ kernel or any of <v5.12 stable maintained trees.

They triggered in the past only with the `threadirqs' option on the
commandline and this has been fixed by commit
   81e2073c175b8 ("genirq: Disable interrupts for force threaded handlers")
