 == a15-usermode-support ==
 * A15 instruction support patches committed upstream in time for
   upstream's 1.0 release
 == upstream-omap3-cleanup ==
 * some work on restructuring the omap3 patchset -- it's now basically
   in the right order and the last 'touches several different
   bits of code' jumbo patch has been split
 == other ==
 * sent some patches upstream which address the main things I
   want to get into qemu 1.0 (PL041 audio support and fixing a
   regression in handling multithreaded programs in linux-user mode)
 * A15 KVM planning work and other preparation for Linaro Connect
 * finally tracked down the qemu-on-ARM memory corruption: we
   mmap the code generation buffer at 0x1000000 with MAP_FIXED;
   unfortunately this is now in the middle of glibc's heap...
   (filed as LP:883133)
 * qemu now has a coroutine implementation which defaults to using
   makecontext() if it is present. Unfortunately ARM eglibc provides
   an implementation which always returns ENOSYS, which is a bit
   tricky to detect with a compile time configure check (without
   breaking cross-compilation support).
 * these two things (and some other known bugs) mean that QEMU on
   ARM hosts is basically broken, and will probably continue to be
   since we don't have the spare resource to test and fix bugs
   (beyond those which we need to fix for KVM-on-ARM)
