Progress: * VIRT-65 [QEMU upstream maintainership] + we needed an rc4 for 4.1.0 (predictably), so herded the necessary fixes into it + bug fixing: - LP:1838913 : single-step exceptions were always being taken to EL1, even if the guest configured debug exceptions to go to EL2 or EL3 - LP:1815423 : x86 TCG bug where we were giving the wrong result for SSE float-to-int conversions that raised the 'invalid' exception - LP:1796520 and LP:1839325 : started investigating some sh4 linux-user bugs + code review: - patch to implement aspeed SD controller model - Eric Auger's patchset of minor SMMUv3 fixes - Aspeed GPIO controller model - v3 of the GreenSocs reset-handling refactoring - RTH's preliminary cleanup of handling of PC in arm decoder
