You mean I have to keep something like this?
 generic-y += xor.h
-
-generated-y += syscall_table.h
\ No newline at end of file
+generic-y += syscall_table.h
\ No newline at end of file

and like this?

 generic-y += ucontext.h
-
-generated-y += unistd_32.h
\ No newline at end of file
+generic-y += unistd_32.h
\ No newline at end of file
