2019-12-18nbd: assert that Error** is not NULL in nbd_iter_channel_errorVladimir Sementsov-Ogievskiy
All callers of nbd_iter_channel_error() pass the address of a local_err variable, and only call this function if an error has already occurred, using this function to propagate that error. This is already implied by its name (local_err instead of the classic errp), but it is worth additionally stressing this by adding an assertion to make it part of the function contract. The local_err parameter is not here to return information about nbd_iter_channel_error failure. Instead it's assumed to be filled when passed to the function. This is already stressed by its name (local_err, instead of classic errp). Stress it additionally by assertion.

2019-12-18error: Fix -msg timestamp defaultMarkus Armbruster
-msg parameter "timestamp" defaults to "off" if you don't specify msg, and to "on" if you do. Messed up right in commit 5e2ac51917 "add timestamp to error_report()". Mostly harmless, because "timestamp" is the only parameter, so "if you do" is "-msg ''", which nobody does. Change the default to "off" no matter what. While there, rename enable_timestamp_msg to error_with_timestamp, and polish documentation. Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20191010081508.8978-1-armbru@redhat.com>
2019-12-18vga: cleanup mapping of VRAM for non-PCI VGAPaolo Bonzini
vga_init_vbe is now used only from ISA VGA cards. Since the alias is not needed anymore, remove it (effectively reverting commit 8294a64d7f, "vga: fix vram double-mapping with -vga std and -M pc-0.12", 2012-05-29) and the now unused vbe_mapped field of VGACommonState. The function now consists of a single memory_region_add_subregion call, so we can inline it; this avoids incorrect usage from PCI cards.

2019-12-18hw/i386: Remove the deprecated machines 0.12 up to 0.15Thomas Huth
These machines can't be used reliably for migration anymore, quoting https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04516.html : " due to the introduction of the memory API, the firmware is not migrated correctly from source to destination. On QEMU <1.3 the 0xf0000-0xfffff area is basically a copy of the higher 0xffff0000-0xffffffff area, while on more recent versions it is initialized with zeroes and the firmware copies from 0xffff0000 to 0xf0000. When you migrate from old to new QEMU, after reboot there's nothing at 0xf0000 and bugs ensue. " The pc-0.x machines have been marked as deprecated since QEMU v4.0, so it is time to remove them now. And while we're at it, mark the remaining pc-1.x machine types as deprecated now, too, so that we finally only have "pc-i440fx" and "pc-q35" machine types left (apart from the non-versioned "isapc" and "microvm") once we remove them in a couple of releases.
