=== ARM Status ===
P/omap4: a new kernel (1402.3) based off O/omap4 at 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.

=== 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 ===

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.
