603d3e79b2 qemu: generate signals on tap I/O 
Currently tap does not generate signals on I/O; this causes
network latency to be dependent on the timer tick (1ms without
dyntick, guest dependent with dyntick).  By generating a signal
on I/O, we can inform the guest immediately that a packet has
arrived.

b2eb849d4b CVE-2007-1320 - Cirrus LGD-54XX "bitblt" heap overflow 
I have just noticed that patch for CVE-2007-1320 has never been applied
to the QEMU CVS. Please find it below.

| Multiple heap-based buffer overflows in the cirrus_invalidate_region
| function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and
| possibly other products, might allow local users to execute arbitrary
| code via unspecified vectors related to "attempting to mark
| non-existent regions as dirty," aka the "bitblt" heap overflow.
