Hello bugproxy, or anyone else affected,
Accepted kexec-tools into trusty-proposed. The package will build now

Please help us by testing this new package.

Hi Mauricio,
Yes, the commit 7bb7c2a4bae8 and d8847573a40f should be imported too.
But why not considering the 2.0.7 (+ 2ca220389d21 + 335bad77fb07 +
45b33eb2e70c) ?
Laurent.

Just as an FYI, here are the patches I have stacked on top of _2.0.6_
which is the version in Utopic. In addition I plan on backporting any
working patch stack to Trusty which has the identical version.

Chris,
On top of 2.0.6, you need also
db3c32babc52 kexec/fs2dt : Fix endianess issue with initrd base and size
I'd recommend to take this one also:
7d33c8933ebf ppc64/purgatory: Disabling GCC's stack protection
Again why not considering 2.0.7 with the 3 patches I mentioned in
comment 7 ?
Due to the timing in the Utopic release schedule we no longer sync newer
versions of package into the archive. At this time we generally try to
keep things restricted to bugfixes. Therefore at this point we need to
apply these fixes on top of 2.0.6.
7d33c8933ebf is already applied in our version
Oh and db3c32babc52 was already applied, so the patchset mentioned in
comment #9 is what will be added.

I'm looking into a 2.0.7 merge at the moment. If that looks good we'll merge
2.0.7 then add these patches on top:

Hi Chris Laurent,
Aren't these other 2 ppc64el-specific patches required too?
- kexec/ppc64: Handle reserved memory ranges exported by OPAL firmware.
- kexec/ppc64: Fix up ELF header and dt for PowerNV platform.
I'm not knowledgeable in kexec, but I see those upstream post-2.0.6 as
well.

I was able to get a crash dump with the above patch (but didn't test
crash on the dump file itsself), but I'll check the above since I'm sure
they affect the dump format and actually using crash.
