Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-armhf-armhf-libvirt-raw  9 debian-di-install         fail REGR. vs. 44381

Regressions which are regarded as allowable (not blocking):

    vga: make sure vga register setup for vbe stays intact (CVE-2016-3712).
    
    Call vbe_update_vgaregs() when the guest touches GFX, SEQ or CRT
    registers, to make sure the vga registers will always have the
    values needed by vbe mode.  This makes sure the sanity checks
    applied by vbe_fixup_regs() are effective.
    
    Without this guests can muck with shift_control, can turn on planar
    vga modes or text mode emulation while VBE is active, making qemu
    take code paths meant for CGA compatibility, but with the very
    large display widths and heigts settable using VBE registers.
    
    Which is good for one or another buffer overflow.  Not that
    critical as they typically read overflows happening somewhere
    in the display code.  So guests can DoS by crashing qemu with a
    segfault, but it is probably not possible to break out of the VM.

    vga: factor out vga register setup
    
    When enabling vbe mode qemu will setup a bunch of vga registers to make
    sure the vga emulation operates in correct mode for a linear
    framebuffer.  Move that code to a separate function so we can call it
    from other places too.

commit 3bf1817079bb0d80c0d8a86a7c7dd0bfe90eb82e

    vga: fix banked access bounds checking (CVE-2016-3710)
    
    vga allows banked access to video memory using the window at 0xa00000
    and it supports a different access modes with different address
    calculations.
    
    The VBE bochs extentions support banked access too, using the
    VBE_DISPI_INDEX_BANK register.  The code tries to take the different
    address calculations into account and applies different limits to
    VBE_DISPI_INDEX_BANK depending on the current access mode.
    
    Which is probably effective in stopping misprogramming by accident.
    But from a security point of view completely useless as an attacker
    can easily change access modes after setting the bank register.
    
    Drop the bogus check, add range checks to vga_mem_{readb,writeb}
    instead.
