Include hw/qdev-properties.h less
In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h).
Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead.
hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.
While there, delete a few superfluous inclusions of hw/qdev-core.h.
Touching hw/qdev-properties.h now recompiles some 1200 objects.

Include hw/hw.h exactly where needed
In my "build everything" tree, changing hw/hw.h triggers a recompile of some 2600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h).
The previous commits have left only the declaration of hw_error() in hw/hw.h. This permits dropping most of its inclusions. Touching it now recompiles less than 200 objects.

In my "build everything" tree, changing migration/vmstate.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h).
hw/hw.h supposedly includes it for convenience. Several other headers include it just to get VMStateDescription. The previous commit made that unnecessary.
Include migration/vmstate.h only where it's still needed. Touching it now recompiles only some 1600 objects.

display/bochs: fix pcie support
Set QEMU_PCI_CAP_EXPRESS unconditionally in init(), then clear it in realize() in case the device is not connected to a PCIe bus.
This makes sure the pci config space allocation is big enough, so accessing the PCIe extended config space doesn't overflow the pci config space buffer.
PCI(e) config space is guest writable. Writes are limited by write mask (which probably is also filled with random stuff), so the guest can only flip enabled bits. But I suspect it still might be exploitable, so rather serious because it might be a host escape for the guest. On the other hand the device is probably not yet in widespread use.
(For a QEMU version without this commit, a mitigation for the bug is available: use "-device bochs-display" as a conventional pci device only.)

hw/display: add new bochs-display device
After writing up the virtual mdev device emulating a display supporting the bochs vbe dispi interface (mbochs.ko) and seeing how simple it actually is I've figured that would be useful for qemu too.
So, here it is, -device bochs-display. It is basically -device VGA without legacy vga emulation. PCI bar 0 is the framebuffer, PCI bar 2 is mmio with the registers. The vga registers are simply not there though, neither in the legacy ioport location nor in the mmio bar. Consequently it is PCI class DISPLAY_OTHER not DISPLAY_VGA.
So there is no text mode emulation, no weird video modes (planar, 256color palette), no memory window at 0xa0000. Just a linear framebuffer in the pci memory bar. And the amount of code to emulate this (and therefore the attack surface) is an order of magnitude smaller when compared to vga emulation.
Compatibility wise it works with OVMF (latest git master). The bochs-drm.ko linux kernel module can handle it just fine too. So UEFI guests should not see any functional difference to VGA.
