I am running on SuSE 9.1 (2.6.4-52-smp).

When I ran the make file using the line:

$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

the make ran quickly without error.

However, when I changed that line to:

$(MAKE) -C $(KDIR) M=$(PWD) modules

I seem to be making the entire kernel again.

What's up with that?
