 == cp15-rework ==
  * converted crn=1; still TODO: crn=0, some loose ends; then reassess
    the design in the light of experience doing register conversion
  * I've estimated another two weeks here but this might be out, because
    in practice much of my time is sucked up by 'other' issues
 == other ==
  * tracked down cause of LP:947888 gpg crash bug: newer glibc use
    /proc/self/maps to decide whether a printf format string using '%n'
    is in writable memory, and qemu's maps emulation wasn't good enough
  * fixed a thumb decoder bug where we were treating 'setend' like 'cps'
  * investigated whether we had any conveniently testable cores which take
    advantage of the ARM ARM latitude for UNDEFfing even on failed condition
    code checks (answer, not really but the KVM code to handle this case
    should be small enough not to worry about its not-yet-tested nature)
  * qemu-linaro 2012.03 release (lots of bug fixes, plus exynos4 and
    highbank models thanks to Samsung and Calxeda)
  * code review: imx31 board patches
  * rebased qemu-linaro on upstream and applied some new patches from
    Christoffer for ARM KVM support
  * LP:956799: added ppoll to QEMU arm-linux-user (a one liner...)
  * boot-wrapper: moved initrd load address up so we can handle large
    kernels (like Android!)
  * sent pullreqs for target-arm, arm-devs patchqueues
