=== ARM Status ===
P/omap4: a new kernel (1402.3) based off O/omap4@1206.13 has been
uploaded and it contains the large mmap() fix, armhf architecture
support and some more config syncs against master.

Work on a 3.2 kernel has started.
lp#861296 ("mmap fails to allocate 2030Mb heap on ARM"): the fix has
been committed for [MNOP]/omap4 and L/imx51.

If your name is in the above table, please review your Alpha-2 work
items. Note that Alpha-2 is Thurs Feb 2.


=== Blueprint: hardware-p-kernel-power-management ===
Power Management:
* Crowd-sourcing ALPM testing Wiki:
https://wiki.ubuntu.com/Kernel/PowerManagementALPM
Please follow instructions and test. Note, you may be risking your
data with these tests!
* Exhaustive testing of pm-utils power.d scripts across various machines,
write up and recommendations presented here:
http://zinc.canonical.com/~cking/power-benchmarking/pm-utils-results
Recommend removing journal-commit + readahead power.d scripts
* Complete PCIe ASPM crowd-sourcing, patch deployed in Precise-next
* Investigating reducing psmouse interrupts

=== Status: Precise Development Kernel ===
We have uploaded the 3.2.0-3.8 Ubuntu kernel which is based on latest
upstream v3.2-rc4 kernel. The 3.2.0-3.8 upload also resolved the
remaining armhf build issues. We are still witholding the patches to
drop the i386 non-pae flavor until after the Tech Board discussion
regarding the issue on Mon Dec 12.

Important Upcoming Dates:
* Thurs Feb 2 - Alpha 2 (~8 weeks)

=== Status: CVE's ===
=== CVE Metrics ===


Currently open CVEs for each supported branch:

|| Package || Open ||
|| || ||
|| linux Hardy || 11 (--) ||
|| linux Lucid || 8 (--) ||
|| linux Maverick || 8 (--) ||
|| linux Natty || 8 (--) ||
|| linux Oneiric || 5 (--) ||
|| linux Precise || 5 (--) ||
|| linux-ec2 Lucid || 8 (--) ||
|| linux-fsl-imx51 Lucid || 8 (--) ||
|| linux-mvl-dove Lucid || 8 (--) ||
|| linux-mvl-dove Maverick || 8 (--) ||
|| linux-ti-omap4 Maverick || 8 (--) ||
|| linux-ti-omap4 Natty || 8 (--) ||
|| linux-ti-omap4 Oneiric || 5 (--) ||

|| linux-lts-backport-maverick Lucid || 8 (--) ||
|| linux-lts-backport-natty Lucid || 8 (--) ||
|| linux-lts-backport-oneiric Lucid || 5 (--) ||

We gained a couple of new CVEs this week and closed out the same number
so the overall stats remain static. We only have fixes for two of the
remaining CVEs.
