Changes since v1: create a wrapper function named qemu_daemon() in oslib-posix.c
instead of putting the OS specific workaround in qemu-nbd.c directly.
On OSX >= 10.5, daemon() is deprecated, resulting in the following warning:

Make the Neon helpers for various floating point operations take an
explicit pointer to the float_status they use, so they don't rely on
the global environment pointer any more. This also allows us to drop
the mul/sub/add helpers completely and just use the vfp versions.

This patchset is largely aimed at rolling back the changes from an
earlier patchset of mine:

flags by having them use the global env.

This removes scsi-disk and scsi-generic's handling of requests
that should be entirely within the realm of the target.

This is the second part of my SCSI work. The first is still pending
and this one is incomplete, but I still would like to get opinions
early enough because this design directly affects the UI.
This series is half of the work that is necessary to support multiple
LUNs behind a target. The idea is
When a logical unit is hung directly below an HBA, we want to introduce
the "missing levels" to avoid duplicating generic target code across
all devices. To do this, I introduce a callback in qdev that is given
the bus specified by the user, and returns the actual bus to use.

This gives each SCSIBus and SCSIDevice a position on the SCSI hierarchy:
- a SCSI_HOST dispatches on the "path" (aka "bus" aka "channel") axis.
- a SCSI_PATH dispatches on the target axis.
- a SCSI_TARGET dispatches on the LUN axis and handles requests for
REPORT LUNS commands, invalid LUNs, a

Not just that. If you had a memory block at say 1 GB - 2 GB, and another

This adds support for parsing a hierarchical LUN and mapping the
result to the qdev hierarchy.

The scsi-id may be a LUN value or a target id. The bus knows,
so add a callback to that end. The default value in case there is
no implementation is to always returns zero.

This provides the infrastructure for simple devices to pick LUNs.
Of course, this will not do anything until there is a device that
can report the existence of those LUNs.

SAM logical unit numbers are complicated beasts that can address
multiple levels of buses and targets before finally reaching
logical units. Begin supporting them by correctly parsing vSCSI
LUNs.
Note that the current (admittedly incorrect) code switched from
a "bus X, target 0, lun 0" representa
Functions like ldl_be_p and ldl_le_p are currently used only as building
blocks for {ld,st}XX_p. As such, they are in cpu-all.h even though they
have absolutely no dependency on the target.
In order to make them globally available, this series moves them to
bswap.h instead.

Hi,
While trying to use qemu -cpu pentium3 to test for incorrect uses of certain
SSE2 instructions, I found that QEMU allowed the mfence and lfence
instructions to be executed even though Pentium 3 doesn't support them.
According to the processor specs (and experience on a real Pentium 3), these
