Default Lucid Patch Review

Below is our review of the patches we are carrying in Lucid as of
2.6.32-4.5. They are split into some logical sections, those we are
clearly keeping, those which clearly should be dropped, and those which
require further study. For the latter we are looking to those who remember
the patches to chime in as appropriate. If you have comments please do
so on this thread. We will likely start the process of dropping patches
shortly.

The following patches are our own patches which we are not pushing
upstream and we expect to continue to carry:

0002-UBUNTU-SAUCE-no-up-Enable-ubuntu-extra-subdirectory.patch
0003-UBUNTU-SAUCE-no-up-ports-Build-drivers-in-ubuntu-sub.patch

0145-UBUNTU-SAUCE-trace-add-trace-events-for-open-exec-an.patch
ureadahead tracing from Scott James Remnant <scott@ubuntu.com>


The patches below all either are now upstream in some form or clearly
no longer needed. These will be dropped:

0034-UBUNTU-SAUCE-Lower-warning-level-of-some-PCI-message.patch
we are already dropping the default output level so this is
not needed

0040-UBUNTU-SAUCE-tulip-Define-ULI-PCI-ID-s.patch
this is already upstream in another form

0047-UBUNTU-SAUCE-Correctly-blacklist-Thinkpad-r40e-in-AC.patch
this appears to have gone upstream and then been removed once
it was fixed, this patch is also has been dammaged around the
karmic rebase and includes some code it should not for the
Medion 41700

0050-UBUNTU-Add-Dell-Dimension-9200-reboot-quirk.patch
this is already upstream

0053-mac80211-fix-two-issues-in-debugfs.patch
this claims to be fixed in 2.6.27

0056-UBUNTU-SAUCE-Dell-laptop-digital-mic-does-not-work-P.patch
0057-UBUNTU-SAUCE-Enable-HDMI-audio-codec-on-Studio-XPS-1.patch
these are backport of an upstream fix and should be not required

0061-UBUNTU-SAUCE-LPIA-Reboot-fix-for-Intel-Crownbeach-de.patch
0062-UBUNTU-SAUCE-LPIA-Logical-reset-of-USB-port-on-resum.patch
both lpia specific and therefore no longer enabled

0063-UBUNTU-SAUCE-Link-acpi-cpufreq.o-first.patch
this is already linked first, and indeed the patch adds only a
blank line

0068-UBUNTU-SAUCE-Dell-XPS710-reboot-quirk.patch
this is already upstream in another form

0075-UBUNTU-SAUCE-default-ATI-Radeon-KMS-to-off-until-use.patch
we now want to enable Radeon by default

The next block all appear to be upstream material and should be pushed
upstream, I include the owners to make this easier:

0029-UBUNTU-SAUCE-PATCH-Add-extra-headers-to-linux-libc-d.patch
0035-UBUNTU-SAUCE-Catch-nonsense-keycodes-and-silently-ig.patch
0048-UBUNTU-SAUCE-Enable-an-e1000e-Intel-Corporation-8256.patch

0058-UBUNTU-Fix-webcam-having-USB-ID-0ac8-303b.patch
Jani Monoses <jani@ubuntu.com>

0084-UBUNTU-SAUCE-ipw2200-Enable-LED-by-default.patch

0085-UBUNTU-SAUCE-Added-quirk-to-recognize-GE0301-3G-mode.patch
Manoj Iyer <manoj.iyer@canonical.com>

0069-UBUNTU-SAUCE-hotkey-quirks-for-various-Zeptro-Znote-.patch
0156-UBUNTU-Upstream-add-local-prefix-to-oss-local-change.patch
Andy Whitcroft <apw@canonical.com>

The remainder need more review, for each I point out the original
submitter in the hope they can help us understand whether these patches
are still needed:

0030-UBUNTU-SAUCE-make-fc-transport-removal-of-target-con.patch
Amit Kucheria <amit.kucheria@ubuntu.com>
This patch was highly resisted upstream and is now very old
indeed, it is entirly possible this is now fixed some other way.

0032-UBUNTU-SAUCE-Restore-VT-fonts-on-switch.patch
Stefan Bader <stefan.bader@canonical.com>
Again this is very old, do we still have issues here? I suspect
with KMS in the mix it is no longer required.

0036-UBUNTU-SAUCE-input-mouse-alps-Do-not-call-psmouse_re.patch
Ben Collins <bcollins@ubuntu.com>
This one stops us reseting alps mice on resume. Again pretty
anchient, I would like to drop it to see if things break these
days.

0037-UBUNTU-SAUCE-Guest-OS-does-not-recognize-a-lun-with-.patch
Tim Gardner <tim.gardner@canonical.com>
This I think is only required with very old vmware? Is it still
required?

0038-UBUNTU-SAUCE-r8169-disable-TSO-by-default-for-RTL811.patch
Phillip Lougher <phillip@ubuntu.com>
This claims to be a temporary work around for a problem, added
in Jun 2007. Is it still needed.

0039-UBUNTU-SAUCE-tulip-Let-dmfe-handle-davicom-on-non-sp.patch
Ben Collins <bcollins@ubuntu.com>
This appears to pass some devices off to another driver. The tulip
driver doess seem to handle handing them off another way, though
its not clear its all devices or not. Is this still needed.

0041-UBUNTU-SAUCE-hostap-send-events-on-data-interface-as.patch
Matthew Garrett <mjg59@srcf.ucam.org>
This duplicates packates on both sides of the hostap interface.
Seem incomplete following driver changes, and I think it was to
work round broken userspace. Is this still needed.

0045-UBUNTU-SAUCE-fix-kernel-oops-in-VirtualBox-during-pa.patch
Colin Ian King <colin.king@canonical.com>
Its not clear that this additional locking is still needed.
Need to test without this patch.

0046-Revert-Bluetooth-Eliminate-checks-for-impossible-con.patch
Colin Ian King <colin.king@canonical.com>
This looks safe enough but do we really need it any more?

0071-UBUNTU-SAUCE-Add-MODULE_ALIAS-for-Dell-WMI-module.patch
Tim Gardner <tim.gardner@canonical.com>
This is waiting for a more correct upstream fix. Has that
appeared?

0073-UBUNTU-Upstream-mmc-prevent-dangling-block-device-fr.patch
Stefan Bader <stefan.bader@canonical.com>
This is waiting for a more correct upstream fix. Has that
appeared?

0077-UBUNTU-SAUCE-Add-config-option-to-set-a-default-LSM.patch
John Johansen <john.johansen@canonical.com>
This I believe has hit upstream security tree and likely to
appear in 2.6.33.

0079-UBUNTU-Upstream-PATCH-dell-laptop-Fix-rfkill-state-q.patch
Matthew Garrett <mjg@redhat.com>

0080-UBUNTU-Upstream-drop-after-2.6.31-dell-laptop-don-t-.patch
0081-UBUNTU-Upstream-drop-after-2.6.31-compal-laptop-Add-.patch
0082-UBUNTU-Upstream-drop-after-2.6.31-compal-laptop-Repl.patch
0114-UBUNTU-SAUCE-drop-after-2.6.31-input-Add-support-for.patch
0115-UBUNTU-SAUCE-drop-after-2.6.31-dell-laptop-Trigger-r.patch
0129-UBUNTU-SAUCE-dell-laptop-Store-the-HW-switch-status-.patch
0130-UBUNTU-SAUCE-dell-laptop-Blacklist-machines-not-supp.patch
Mario Limonciello <Mario_Limonciello@Dell.com>
This lot seem to be dell related updates which claim to be
on their way upstream. Mario are they there yet?

0091-UBUNTU-staging-android-disable.patch
0094-UBUNTU-staging-comdi-disable.patch
0095-UBUNTU-staging-go7007-disable.patch
Andy Whitcroft <apw@canonical.com>
All broken drivers currently.

0119-UBUNTU-Upstream-acerhdf-Limit-modalias-matching-to-s.patch
Stefan Bader <stefan.bader@canonical.com>
This is waiting for a more correct upstream fix. Has that
appeared?
