There's some macros on powerpc I could look at. It duplicates quite a bit, at least (F)SREG/(F)LREG blocks could be reused.

When I was investigating on that (I hoped ppc critical interrupts would not be disabled by interrupt disable) I found navigating them a little annoying for readability as someone that did not know what exactly they were doing.
