My core2duo patch introduced a vague statement of "missing features" in
the CPUID specification. This patch addresses this by specifying exactly
what is missing.
While going along the missing CPUID entries I also stumbled across
invalid and missing CPUID #defines while comparing them to the Intel
Documentation. This patch also addresses these. I found them too minor
to split them up in a separate patch.
Furthermore I looked through CPUID functions > 5 and realized that it
should be safe to bump the level to 10. I tried booting Linux with that
and it worked fine.

Implement an fd pool to get real AIO with posix-aio
This patch implements a simple fd pool to allow many AIO requests with
posix-aio. The result is significantly improved performance (identical to that
reported for linux-aio) for both cache=on and cache=off.
The fundamental problem with posix-aio is that it limits itself to one thread
per-file descriptor. I don't know why this is, but this patch provides a simple
mechanism to work around this (duplicating the file descriptor).
This isn't a great solution, but it seems like a reasonable intermediate step
between posix-aio and a custom thread-pool to replace it.
Ryan Harper will be posting some performance analysis he did comparing posix-aio
with fd pooling against linux-aio. The size of the posix-aio thread pool and
the fd pool were largely determined by him based on this analysis.

Refactor AIO to allow multiple AIO implementations
This patch refactors the AIO layer to allow multiple AIO implementations. It's
only possible because of the recent signalfd() patch.
Right now, the AIO infrastructure is pretty specific to the block raw backend.
For other block devices to implement AIO, the qemu_aio_wait function must
support registration. This patch introduces a new function,
qemu_aio_set_fd_handler, which can be used to register a file descriptor to be
called back. qemu_aio_wait() now polls a set of file descriptors registered
with this function until one becomes readable or writable.
This patch should allow the implementation of alternative AIO backends (via a
thread pool or linux-aio) and AIO backends in non-traditional block devices
(like NBD).

LSI SCSI: raise UDC on infinite loop (Marcelo Tosatti)
Raise UDC (Unexpected Disconnect) when a large enough number of
instructions has been executed by the SCRIPTS processor. This "solution"
is much simpler than temporarily interrupting execution.
This remedies the situation with Windows which downloads SCRIPTS code
that busy loops on guest main memory. Their drivers _do_ handle UDC
appropriately (at least XP and 2003).
It would be nicer to actually detect infinite loops, but until then,
this bandaid seems acceptable.
Since the situation seems to be rare enough, raise the number
of instructions to 10000 (previously 1000).
