=== 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.

  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)

  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.

  We gained yet another 5 CVEs this week.  We closed out a couple.  Two of
  the new CVEs await upstream fixes.
