What is the preferred way to achieve atomicity in an operation now that
cli() and sti() are gone?

The point of asm-generic is not to use the files, but to give porters a
hint about the functionality. Quoting asm-generic/bitops.h:
/* For the benefit of those who are trying to port Linux to another
* architecture, here are some C-language equivalents. You should
* recode these in the native assembly language, if at all possible.
* To guarantee atomicity, these routines call cli() and sti() to
* disable interrupts while they operate. (You have to provide inline
* routines to cli() and sti().) */
Or is this comment wrong, too?
