🦋 SYNOPSIS 🦋

an error is returned if the registration has already been done previously 😭 like, once is enough, bestie — it's not gonna let you double-register.

the kernel file lives right here: ./arch/arm/include/asm/mcpm.h — go read it, iykyk 📖

and it's giving friend group, because these all hang out together:

• mcpm_is_available(9)
