Progress: * UM-2 [QEMU upstream maintainership] - investigated and fixed a few bugs in FEAT_MOPS; patches sent - reviewed patch fixing bug in virt ACPI table for debug UART; added the necessary update-the-reference-files patches for 'make check'. Debugged why it broke console output on Linux -- turns out that Linux has a bug where acpi_parse_spcr() and pl011_console_match() disagree about how the former should tell the latter "use 16-bit MMIO"... We'll work around this by having the ACPI table report 32-bit MMIO; Raspberry Pi 4 firmware on real hardware already does that, so it should be a safe choice. - sent patch fixing failure to report BTI GP state correctly when doing a two-stage page table walk - code review and assembly of a pull request (softfreeze next week...)

* QEMU-292 [ARMv8.3 FEAT_NV, Nested Virtualization] - got to a (hopefully) code-complete but untested state; will probably put this to one side for the moment leading up to softfreeze - tracked down the kernel and kvmtool patchsets that will be needed to test this (they are not upstream yet)
