This patch fixes migration so that it works on Win32. This requires using
socket specific calls since sockets cannot be treated like file descriptors
on win32.

The live migration code broke the windows build. As part of this
change, I've switched the BIOS path to C:\Program Files\Qemu instead of
/c/Program Files/Qemu. The later is only valid when launching from MSYS
but the former is always valid.

Since revision 5228, we don't register the memory hole (0xa00000 to
0xfffff) anymore. As a consequence, we don't need to register it again
as unassigned.

* Drop DMA poll mode. Instead immediately push rx frames straight into the DMA
without waiting for DMA_run to poll them of the fifo.

could be expanded). This also fixes the bug with mips elf64 symbols
in current Qemu trunk.
* Use quicksort and binary search for symbol lookup.
* Remove unneeded entries from symbol table. This reduced a typical table
size (linux mips kernel) from 1764487 to 11656 entries.

Make "host:" usb devices work again on systems that have the
file /proc/bus/usb/devices. This was broken in r5441 due to
incorrect logic for the USB_FS_SYS case in usb_host_scan().

this patch allows to fully use a tape device connected to qemu through
the scsi-generic interface.
Previous patch introduced tape SCSI commands management, this one
improve error case management:
- the SCSI controller command completion must be called with the status
value, not the sense value. In the case of scsi-generic, the SCSI status
is given by the field status of sg_io_hdr_t (the value is left shifted
by one regarding status codes defined in /usr/include/scsi/scsi.h)
- when a read is aborted due to a mark/EOF/EOD/EOM, the len reported to
controller can be 0. LSI controller emulation doesn't know how to manage
this. A workaround found is to call the completion routine with
SCSI_REASON_DONE just after calling it with SCSI_REASON_DATA with len=0.
This patch also manages correctly the block size of the tape device.
This patch has been tested with a real tape device "HP C5683A", linux
guest (debian etch) and tools like "mt", "tar" and "btape".
Windows guest is not better supported than before...

With SVM the TLB supports tagging to distinguish TLB entries from
different virtual CPUs. This tag is called an ASID. The amount of ASIDs is
given in EBX of the SVM-CPUID-leaf. Currently we return 0, which might
break hypervisors. Let's better return something >0 here, say 0x10.
Since we're flushing the complete TLB on every VM entry and exit we're not
making use of the ASID information anyways.

This patch adds a CPU definition for the Core Duo CPU. I tried to
resemble the original as closely as possible and document what features
are missing still. This patch enables the use of a recent CPU definition
on 32 bit platforms.
It also fixes two issues that went along the line:
- invalid xlevel in core2duo spec
While looking though the CPUIDs again, I found that xlevel is actually 8.
- non-PSE36 support
The CoreDuo CPUID does not expose the PSE36 capability, but CPUID
0x80000008 is tied to 36 bits. This broke Windows XP installation for
me, so I just set it to 32 bits width when PSE36 is not available. The
original CPU also exposes 32 bit width in CPUID 0x80000008.

This patch changes the cache= option to accept none, writeback, or writethough
to control the host page cache behavior. By default, writethrough caching is
now used which internally is implemented by using O_DSYNC to open the disk
images. When using -snapshot, writeback is used by default since data integrity
it not at all an issue.
cache=none has the same behavior as cache=off previously. The later syntax is
still supported by now deprecated. I also cleaned up the O_DIRECT
implementation to avoid many of the #ifdefs.
