Progress: * VIRT-65 [QEMU upstream maintainership] + sent another patch related to linux-user signal frames (a wrinkle I had thought had no effect with SVE disabled turns out to be relevant in the no-SVE case too) + testing and applying patches for 2.12 rc4 + code review: - latest spin of the SMMUv3 emulation patches - some last-minute fixes to our softfloat refactoring - memory barrier handling in the 32-bit arm TCG backend was broken + tracked down a zephyr test failure on QEMU as the same bug in the Zephyr timer device driver as the one I reported 6 months ago... + sent a patch fixing linux-user emulation of getdents syscall for 64-bit guest on 32-bit host + sent a patchset that removes the long-standing "only 4 serial ports" limit in QEMU (various Arm boards really have 5 or 6) + some patches fixing errors in arm boards that don't properly register all their RAM regions for migration
