--- 7.4 mandatory-y
- mandatory-y is essentially used by include/(uapi/)asm-generic/Kbuild.asm
+ mandatory-y is essentially used by include/(uapi/)asm-generic/Kbuild
to define the minimum set of ASM headers that all architectures must have.
This works like optional generic-y. If a mandatory header is missing
