2022-07-12iotests/297: Have mypy ignore unused ignoresHanna Reitz
e7874a50ff3f5b20fb46f36958ad ("python: update for mypy 0.950") has added `warn_unused_ignores = False` to python/setup.cfg, to be able to keep compatibility with both pre- and post-0.950 mypy versions. The iotests' mypy.ini needs the same, or 297 will fail (on both pre- and post-0.950 mypy, as far as I can tell; just for different `ignore` lines).

2022-07-12qsd: Do not use error_report() before monitor_initHanna Reitz
error_report() only works once monitor_init_globals_core() has been called, which is not the case when parsing the --daemonize option. Use fprintf(stderr, ...) instead.

2022-07-12accel/tcg: Fix unaligned stores to s390x low-address-protected lowcoreIlya Leoshkevich
If low-address-protection is active, unaligned stores to non-protected parts of lowcore lead to protection exceptions. The reason is that in such cases tlb_fill() call in store_helper_unaligned() covers [0, addr + size) range, which contains the protected portion of lowcore. This range is too large. The most straightforward fix would be to make sure we stay within the original [addr, addr + size) range. However, if an unaligned access affects a single page, we don't need to call tlb_fill() in store_helper_unaligned() at all, since it would be identical to the previous tlb_fill() call in store_helper(), and therefore a no-op. If an unaligned access covers multiple pages, this situation does not occur. Therefore simply skip TLB handling in store_helper_unaligned() if we are dealing with a single page.

This fixes a bug in POSIX-compliant environments. Since we had allocated a buffer named 'tcg-jit' with read-write access protections we need a int type to combine these access flags and return it, whereas we had inexplicably return a bool type.

2022-07-11linux-user/aarch64: Move sve record checks into restoreRichard Henderson
Move the checks out of the parsing loop and into the restore function. This more closely mirrors the code structure in the kernel, and is slightly clearer. Reject rather than silently skip incorrect VL and SVE record sizes, bringing our checks in to line with those the kernel does.

In parse_user_sigframe, the kernel rejects duplicate sve records, or records that are smaller than the header. We were silently allowing these cases to pass, dropping the record.
