I maintain the qla2xxx driver and have been noticing some build
problems also.  I typically do most compiling and editing of the
driver outside of the kernel tree, i.e. my make command usually takes
on the form:

	-bash-2.05b# make -C /usr/src/linux-2.6.5-mm3 SUBDIRS=$PWD modules
	make: Entering directory `/usr/src/linux-2.6.5-mm3'
	*** Warning: Overriding SUBDIRS on the command line can cause
	***          inconsistencies
	make[1]: `arch/i386/kernel/asm-offsets.s' is up to date.

With 2.6.5-mm4 a similar command fails with:

	-bash-2.05b# make -C /usr/src/linux-2.6.5-mm4 SUBDIRS=$PWD modules
	make: Entering directory `/usr/src/linux-2.6.5-mm4'

I've even tried the 'M=...' syntax documented in the Makefile:

So, what am I missing?  I can provide other logs if needed, just tell
me what you need.
