--- 7.4 mandatory-y
|
||||
|

mandatory-y is essentially used by include/uapi/asm-generic/Kbuild.asm
|
||||
to define the minimum set of headers that must be exported in
|
||||
include/asm.
|
||||
mandatory-y is essentially used by include/(uapi/)asm-generic/Kbuild.asm
|
||||
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
|
||||
in arch/$(ARCH)/include/(uapi/)/asm, Kbuild will automatically generate
|
||||
a wrapper of the asm-generic one.
|
||||
|
||||
The convention is to list one subdir per line and
|
||||
preferably in alphabetic order.
