Since 5.3 kernel commit 7e35b42591c0 ("kbuild: remove SUBDIRS support"),
SUBDIRS has been removed. We can only use make M=dir or set the environment
variable KBUILD_EXTMOD to specify the directory of external module to build.

Hi Xu,
One missing Makefile:

Is it necessary to update these comments? In other words, could we
remove these comments directly?

These makefiles all have the following comment:
#
# Makefile for GCOV profiling kernel module
#
#KERNELDIR := /usr/src/linux-2.5.64-gcov
It maybe used to test kernel module coverage. I am not sure.
I guess we can remove them in a separate patch if they are useless after
discussion.
@cyril,petr,Li Do you have some advise for these comments?

Since 5.3 kernel commit 7e35b42591c0 ("kbuild: remove SUBDIRS support"),
SUBDIRS has been removed. We can only use make M=dir or set the environment
variable KBUILD_EXTMOD to specify the directory of external module to build.
