Split VNC defines to vnc.h (Alexander Graf)

The VNC protocol contains quite some constants, some of which are
currently hardcoded in the vnc.c code. This is not exactly pretty.

Let's move all those constants out to vnc.h, so they are clearly
separated. While at it, I also included other defines that will be
used later in this patch series.

kvm-x86: Remove eflags conversion into emulator format (Jan Kiszka)

It seems that the conversion of the kernel-delivered eflags state into
qemu's internal split representation was once needed in an older kvm
design (register read-back may have taken place from inside cpu_exec).
Today it is plain wrong and causes incorrect cpu state reporting (gdb,

Check if the i8254 timer is active before deactivating it (Alexander Graf)

The HPET emulation can disable the i8254 when the HPET is
in legacy mode, thus emulating the i8254's behavior.

But if it does, the i8254 doesn't have to be running, so
let's check to see if the timer works and not disable it

MTRR support on x86 (Carl-Daniel Hailfinger)

The current codebase ignores MTRR (Memory Type Range Register)
configuration writes and reads because Qemu does not implement caching.
All BIOS/firmware in know of for x86 do implement a mode called
Cache-as-RAM (CAR) which locks down the CPU cache lines and uses the CPU
cache like RAM before RAM is enabled. Qemu assumes RAM is accessible
from the start, but it would be nice to be able to run real
BIOS/firmware in Qemu. For that, we need CAR support and for CAR support
we have to support MTRRs.

This patch is a first step in that direction. MTRRs are MSRs supported
by all recent x86 CPUs, even old i586. Besides influencing cache, the
MTRRs can be written and read back, so discarding MTRR writes violates
the expectations of existing code out there.

An added benefit of this patch is that it fixes the following Linux
kernel error message present in recent kernels (provided the BIOS has
the recent MTRR patches applied):

It's useful, together with the highest-allocation, to figure out how

For example when the highest allocation is high (almost end-of-disk), but
many bytes (clusters) are free, and can be re-allocated when neeeded, than
we know it's probably not going to reach end-of-disk-space soon.

much more allocation can be done for the block device.

Vectored block device API (Avi Kivity)

Most devices that are capable of DMA are also capable of scatter-gather.
With the memory mapping API, this means that the device code needs to be
able to access discontiguous host memory regions.

For block devices, this translates to vectored I/O.  This patch implements
an aynchronous vectored interface for the qemu block devices.  At the moment
all I/O is bounced and submitted through the non-vectored API; in the future
we will convert block devices to natively support vectored I/O wherever
possible.
