CentOS - May 2008 - missing from Centos51 src tree: ".../drivers/infiniband/hw/amso1100/Makefile"

i'm attempting to rebuild centos51 kernel-xen.

(fwiw, because pciback has NOT been compiled into the kernel,
	http://bugs.centos.org/view.php?id=2767)

after,

	yum install kernel-devel kernel-xen-devel

and usual,

	ln -s /usr/src/kernels/`uname -r`-`uname -m` /usr/src/linux
	cd /usr/src/linux
	cp /boot/config-`uname -r` ./.config
	make oldconfig
	make menuconfig
	...

next,

	make rpm

fails at,

	scripts/kconfig/conf -s arch/x86_64/Kconfig
	make clean
	scripts/Makefile.clean:17:
/usr/src/kernels/2.6.18-53.1.19.el5-xen-x86_64/drivers/infiniband/hw/amso1100/Makefile:
No such file or directory
	make[5]: *** No rule to make target
`/usr/src/kernels/2.6.18-53.1.19.el5-xen-x86_64/drivers/infiniband/hw/amso1100/Makefile'.
 Stop.
	make[4]: *** [drivers/infiniband/hw/amso1100] Error 2
	make[3]: *** [drivers/infiniband] Error 2
	make[2]: *** [_clean_drivers] Error 2
	make[1]: *** [rpm] Error 2
	make: *** [rpm] Error 2

checking,

	ls -al \
	/usr/src/kernels/2.6.18-53.1.19.el5-xen-x86_64/drivers/infiniband/hw/amso1100/Makefile
\
	/usr/src/kernels/2.6.18-53.1.19.el5-xen-x86_64/drivers/infiniband/hw/*/Makefile
	
in fact *is* missing,

	/bin/ls:
/usr/src/kernels/2.6.18-53.1.19.el5-xen-x86_64/drivers/infiniband/hw/amso1100/Makefile:

/usr/src/kernels/2.6.18-53.1.19.el5-xen-x86_64/drivers/infiniband/hw/mthca/Makefile


installing & checking original/full SRPM,

	cd /usr/src/redhat/SRPMS
	wget
http://mirror.centos.org/centos/5.1/updates/SRPMS/kernel-2.6.18-53.1.19.el5.src.rpm
	rpm -ivh kernel-2.6.18-53.1.19.el5.src.rpm

it's also missing there,

	ls -al
/usr/src/kernels/2.6.18-53.1.19.el5-x86_64/drivers/infiniband/hw/amso1100/Makefile
	/bin/ls:
/usr/src/kernels/2.6.18-53.1.19.el5-x86_64/drivers/infiniband/hw/amso1100/Makefile:
No such file or directory

where can I get the 'Makefile'?

thanks.

checking further for the Makefile in the latest git repo,

  git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband.git for-linus

, there's also no Makefile in the respective directory,

  ./for-linus/drivers/infiniband/hw/amso1100/

emailed the repo maintainer to ask,

  "is this an omission? if not, where can i get the Makefile?"

and received,

  Reply
  "There is a Kbuild file instead of a Makefile there."

i'm not yet sure what to do with that ... but, i presume that the
'make' process should *not* look for the Makefile? or, is there an
additonal step req'd?

HOUSTON, We have a problem.

It's probably worth mentioning here, that this won't work in any
recent (Centos 4 or 5) release, because kernel-*-devel packages don't
contain any source files. They contain the headers needed to link a
module against the kernel, and that's about it.

If you want to rebuild the kernel, you're going to have to extract the
source from the kernel src.rpm, and follow the instructions on the
wiki.
