Default Updated linux-rt package for Lucid

Dear Kernel Team,

I have updated linux-rt package and placed it in my PPA at:
https://launchpad.net/~abogani/+archive/broken

Brief review of changes from previous release (10.153):
*) Ubuntu Karmic 2.6.31-21.59 is used as base for this kernel for
offer latest general improvements and security fixes.
*) Update the PREEMPT_RT patchset support from rt19 to rt21. This for
fix some "Scheduling while atomic" bugs like:
https://bugs.launchpad.net/ubuntu/+source/linux-rt/+bug/499033
https://bugs.launchpad.net/ubuntu/+source/linux-rt/+bug/540960
And for fix a CPU excessive usage bug:
https://bugs.launchpad.net/ubuntu/+source/linux-rt/+bug/523319

Ciao,
Alessio

OK, so this is mostly a writeup of things I noticed, when I notice them. No
order implied in the order of occurrence,

* You seem to be using sort of an older approach of the debian rules setup.
I think you likely use a git tree as a source as well and I could imagine
it making things simpler for you if you had the (in this case karmic) tree
of us as a base and the rt stuff on top, then you might be able just to
rebase whenever we change.
From the quick look it seems like the rules are modified to support the
approach of patching on the fly. Correct? Nothing wrong with that. Just
trying to show up alternatives here.
One of the options with our new layout is, that you can have all your
configuration separately in a (for example) debian.rt...
* In the changelog I noticed a big jump in the release number in the middle
of Karmic. Just curious why that happened.
* When building the package, the produced packages look ok. I understand the
linux-rt-headers arises from the requirement to have unique naming and still
trying to follow the usual approach to have that common header package for
all flavours. Some of our topic tree packages use no common headers package
there or are save by having unique ABI numbers.
linux-headers-2.6.31-11-rt_2.6.31-11.154_amd64.deb
linux-image-2.6.31-11-rt_2.6.31-11.154_amd64.deb
linux-image-debug-2.6.31-11-rt_2.6.31-11.154_amd64.ddeb
linux-rt-headers-2.6.31-11_2.6.31-11.154_all.deb

Overall the packaging looks reasonable to me, so I guess we should get together
on IRC next week and talk about uploading it. The things I noted down are stuff
to think of going forward and I believe Andy wanted to have a look at the new
flavour for Maverick. So we can probably talk together.

Regards,
Stefan

One addition to the debug package as I just realize this: the naming of the
debug packages has changed from
linux-image-debug-<abi version>-<flavour>_<version>_<arch>.ddeb
to
linux-image-<abi version>-<flavour>-dbgsym_<version>_<arch>.ddeb
(eg. linux-image-2.6.31-11-rt-dbgsym_2.6.31-11.154_amd64.ddeb)

Archive exceptions currently handle both versions, but long term this should
become the new format.
