Re: Linux null-pointer deref in 3.16.7-ctk2-1 (was: Bug#776192: upgrade-reports wheezy to jessie boot problem)

Bug link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=776192 Thanks, ~Niels Any news on this problem? I am still seeing this problem even though we have moved on to 3.16.7-ckt7-1. I had the thought to look at the kernel modules that support the PERC controller on these Dell systems. Explicitly specifying the mpt* modules and updating initramfs does not fix the problem. We have plenty of these 1950s. I really need to come up with a work around or a solution to this problem. Any ideas about what I should try next?

The fix was cherry-picked in 3.16.7-ckt1 (commit 01eca100c06d) and the current packages in testing/unstable are based on 3.16.7-ckt7.

Actually, I guess there's nothing preventing you building a armhf kernel
with a compiler not having __ARM_PCS_VFP defined by default, but I'm not sure
we should take care of this case. One can always use KBUILD_DEBARCH=armhf.

[PATCH 4/4] RFC: builddeb: add linux-tools package with perf
From: Riku Voipio riku.voi...@linaro.org
Perf is shipped in debian in linux-tools-$version package. Extend
the existing to builddeb script to build perf if BUILD_TOOLS=y
is added the make deb-pkg line
Some features of this patch I'm uncomfortable with:
1. Relative paths are resoved to absolute ones
Especially with separate O= buildd, perf build from tools/perf dir
fail.
2. Unsetting LDFLAGS
make - shell (builddeb) - make expands variables. The LDFLAGS as
set by toplevel makefile are for kernel, so we just unset the flag
here.
3. Replaces ubuntu/debian packages instead attempting to fit to
the linux-base/linux-tools-common frameworks. I think people who
want to run make deb-pkg for their kernels would rather keep this
simple.
4. More tools than just perf could be built - unfortunately most
tools fail to have a working install target and/or else have
build process inconsistent with other tools. A topic for another
patch series.

[PATCH 1/4] deb-pkg: Add automatic support for armhf architecture
From: Ben Hutchings b...@decadent.org.uk
The Debian armhf architecture uses the ARM EABI hard-float variant,
whereas armel uses the soft-float variant. If the compiler used
to compile the kernel uses the __ARM_PCS_VFP ABI, the compiler
targets armhf architecture.
v3 by Riku: Use gcc define instead of CONFIG_VFP

Actually, I guess there's nothing preventing you building a armhf kernel
with a compiler not having __ARM_PCS_VFP defined by default, but I'm not sure
we should take care of this case. One can always use KBUILD_DEBARCH=armhf.
I think the common use cases would be a) native compilers or b)
cross-compiler targeting the same debian architecture as the rootfs.
This patch provides automatic detection for both cases. For corner
cases, one will have to manually specify KBUILD_DEBARCH - which one
already had to do if one was targeting armhf.

$CC should be used together with $KBUILD_CFLAGS to behave the same as
