Progress:
* VIRT-65 [QEMU upstream maintainership]
+ put some reviewed MPS device patches into master, did a v2 of the
rest and sent them out again; these are now in master
+ ditto with patches for missing AArch32-Hyp features
+ code review:
- rth's patchset fixing float/int-with-scaling conversion
- rth's patchset adding system mode support for SVE
- linux-user: netlink fixes
+ sent out a patchset that wires up the GICv2 virtualization
memory regions and IRQs on the remaining boards that need it;
got this into master
thanks

Hi, dear toolchain team
I'm working on a Cavium ThunderX and want to install the latest Linaro binary release 7.3.1, but it seems no aarch64 native binaries in https://releases.linaro.org/components/toolchain/binaries/latest/aarch64-li…
Can you help on this, thanks very much!
Best Regards, Yi

SVE Support ([VIRT-198])
========================
- looked at re-factoring fcvt tests to add tests for rth's recent
fixes
- see [my initial test branch]
- the idea is to make adding a new op test case minimal effort

- Started working on "My Other Machine is Virtual" talk for YVR18
- use-case: find hot-block in pure CPU code
- use-case: trace disk activity on system boot
- Added another story to the [Instrumentation EPIC]
[Instrumentation EPIC] https://projects.linaro.org/browse/TCWG-1457
