 The version.h thing deserves a slightly more explicit commit message, like:

The cryptodev-linux Makefile defines the following:

build: version.h
        make ${KERNEL_MAKE_OPTS} modules

modules_install:
        make -C $(KERNEL_DIR) SUBDIRS=`pwd` modules_install
        @echo "Installing cryptodev.h in $(PREFIX)/usr/include/crypto ..."
        @install -D crypto/cryptodev.h $(PREFIX)/usr/include/crypto/cryptodev.h

So when we use the kernel-module infrastructure, we have to explicitly handle
version.h and cryptodev.h. cryptodev.h was already handled specifically because
it goes to STAGING_DIR. For version.h, we add a pre-build hook.


 That said, SUBDIRS= does not behave exactly the same as M=, but I don't know
what the difference is. So that part should probably be mentioned explicitly in
the commit message as well.

 PREFIX is only used for installing cryptodev.h, which is now no longer done. So
we don't need to define it, right? Same for KERNEL_DIR, it's only used by the
rules we no longer use.

 If you remove these, it should of course also be mentioned explicitly in the
commit message.

 Arnout
