Merge tag 'kbuild-v4.21-3' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

Pull more Kbuild updates from Masahiro Yamada:

 - improve boolinit.cocci and use_after_iter.cocci semantic patches

 - fix alignment for kallsyms

 - move 'asm goto' compiler test to Kconfig and clean up jump_label
   CONFIG option

 - generate asm-generic wrappers automatically if arch does not
   implement mandatory UAPI headers

 - remove redundant generic-y defines

 - misc cleanups

 --- 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.
