Mostly, Error ** is for returning error from the function, so the callee sets it. However error_append_security_model_hint and error_append_socket_sockfd_hint get already filled errp parameter.

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.
