qemu meeting status

Hi guys. I just realized that today's meeting will be right in the middle of dinner plans. I'll organize better next week. Anyway, here's my status:

- Fourth SME patch set -- parts merged, and some bugs fixed. - Base/arm-compat portion of semihosting rewrite now upstream. Target-specific bits for m68k, mips, nios2, xtensa outstanding. - Almost done with FEAT_HAFDBS (hardware access/dirty updates). Big changes to ptw.c to make that work: 50+ patches. The reorg should make FEAT_RME easier though.
