357c692cca Revert r5636 to fix icount on hosts w/o high-res clocks
Changeset r5636 changed the timers to run in the alarm callback.  The 
alarm callback can only be called as frequently as the host alarm timer 
fires.  For older Linux hosts and possibly non-Linux hosts, this can be 
as high as a 1ms granularity.

icount calculates the select timeout based on the next deadline and 
select is usually capable of sleeping for a short period of time than 
alarm timer granularity.  This means that changing the timer callbacks 
to be based on alarm firing caused timers to fire much later than they 
ought to when using icount.

2bec46dc97 vga optimization (Glauber Costa)
Hypervisors like KVM perform badly while doing mmio on
a loop, because it'll generate an exit on each access.
This is the case with VGA, which results in very bad
performance.

In this patch, we map the linear frame buffer as RAM,
make sure it has dirty region tracking enabled, and then
just let the region to be written.

8f2e8d1f80 e1000 VLAN offload emulation (Alex Williamson)
We're currently ignoring the e1000 VLAN tagging, stripping and filtering
features in the e1000 emulation.  This patch adds backing for the
relevant registers and provides a software implementation of the
acceleration, such that a guest can make use of VLANs.

This is mostly (only?) useful for a guest on a bridge (not user mode
networking).  The only caveat beyond that is that you need to make sure
the host NIC isn't doing it's own tagging, stripping, or filtering.
This generally means the host NIC on the bridge should not be part of a
VLAN.

21cafd08a6 uImage: return base load address (Hollis Blanchard)
Return the base address at which the image was loaded so that callers may keep
track of currently occupied guest memory.

This will be required by the PPC 440 embedded code to avoid hard coding a
device model/initrd location.  Other users of this function could make use of
this parameter to avoid hard coding these locations in the future too.
