Default Bug#649394: linux-source-2.6.32: can't build 2.6.32-5 using 2.6_2.6.32-34squeeze1

Package: linux-source-2.6.32
Version: 2.6.32-38
Severity: normal

I'm running 2.6.32-5-xen-amd64 and I'd like to compile a new vmlinuz
with enhanced errno reporting (distinguish between ENOMEM returns
in fork.c). When I try to build 2.6.32-5, it applies all the patches
through 34squeeze1 (and actually fails to do that as one of the
later patches conflicts with my change).

What I did:

dpkg-source -x linux-2.6_2.6.32-34squeeze1.dsc
/usr/src/kernel-patches/all/2.6.32/apply/debian 5
cd linux-2.6-2.6.32
vi kernel/fork.c
fakeroot make -f debian/rules.gen binary-arch_amd64_xen

What happened:

(all the rest of the patches started to apply, and failed at version
14 where there was another edit to fork.c, so the build
failed)

What I expected:

A build without all the rest of the patches being applied.



Variant:

in "What I did", I tried this also, and all the patches still got
applied:

dpkg-source -x linux-2.6_2.6.32-34squeeze1.dsc
/usr/src/kernel-patches/all/2.6.32/apply/debian 5
cd linux-2.6-2.6.32
vi kernel/fork.c
fakeroot make -f debian/rules.gen build_amd64_xen_amd64_real


I looked in the makefiles, and noted that in debian/rules.real, the
apply-patch command definition has no way to specify the patch-level:

define patch_cmd
cd '$(DIR)'; python '$(CURDIR)/debian/bin/patch.apply' --overwrite-home='$(CURDIR)/debian/patches'
endef

Maybe the $(ABINAME) could be used to produce a "patch-level" for this
command?

I'm not all that familiar with building Debian kernels from source, I'd
be happy to learn the "right way" if I was doing it wrong. I was
following instructions from
http://wiki.debian.org/HowToRebuildAnOfficialDebianKernelPackage
and supplemented it by reading the makefiles.
