Now we can safely call AUD_init multiple times we can push it down to
individual audio devices, rather than having to pass it from the board
init.
Signed-off-by: NPaul Brook <paul@codesourcery.com>

Failure to initialize the audio subsystem is not handled consistently.
Where it is handled it has guest visible effects, which is wrong.
We already have a "nosound" audio driver as a last resort, so trying to
proceed without an audio backend seems pointless.

Also protect against multiple calls to AUD_init so that this can be
pushed down into individual devices.

All VGA devices share a common field subset; currently they do so by
a macro which defines the common fields inline their state structures,
relying on the the common state being placed at offset 0 in the structure.
This makes refactoring the code difficult and requires a lot of error prone
casts.

Replace the macro by a new VGACommonState structure, and the casts by
regular field access and container_of() for upcasts.

Remove cpu features that are not supported by kvm from the cpuid features
reported to the guest.
Signed-off-by: NAvi Kivity <avi@redhat.com>
Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

QEMU allows adding or removing cpu features by using the syntax '-cpu +feature'
or '-cpu -feature'.  Some cpuid features cause more than one bit to be set or
cleared; but QEMU stops after just one bit has been modified, causing the
feature bits to be inconsistent.

Fix by allowing all feature bits corresponding to a given name to be set.

When deleting an fd event there is a chance the object doesn't get
deleted, but only ->deleted set positive and deleted somewhere later.

Now, if we create a handler for the fd again before the actual
deletion occurs, we end up writing data into an object that has
->deleted set, which is obviously wrong.

I see two ways to fix this:

1. Don't return ->deleted objects in the search
2. Unset ->deleted in the search

This patch implements 1. which feels safer to do. It fixes AIO issues
I've seen with curl, as libcurl unsets fd event listeners pretty
frequently.

The linux loader is just an option rom like any other, just with
some special requirements. Right now, our option rom resetting
mechanism is not being applied to it. As a result, users using
-kernel will not be able to successfully reboot their machines

This patch fixes it by saving all the data we generated in
the load_linux() function, to be used later by the option rom
resetting mechanism.

Currently, boot options are not preserved across a system reset.
option roms can modify themselves, or can for instance restore the real
int 0x19 vector after they tried to boot from it.

To properly do that, we need a reset handler registered to deal with option
roms. This patch is based on current version on qemu-kvm.git

This is no user-flippable switch, and no arch makes use of disabling
gdbstub support. So it's pointless to keep the related #ifdefs and
configure hunks around - and risking breakages like 711c410fdd again.
