3# The Make variable $(M) must point to the directory that contains the module
4# source code (which includes this Makefile). It can either be an absolute or a
5# relative path. If it is a relative path, then it must be relative to the
6# kernel source directory (KERNEL_SRC). An absolute path can be obtained very
7# easily through $(shell pwd). Generating a path relative to KERNEL_SRC is
8# difficult and we accept some outside help by letting the caller override the
