this patch fixes an issue in symfind.
Assume you have the following symbols:
Address Size
0045bca0 00000080 T s0
0045bd20 00000112 T s1
You'll notice that s1 is s0 + size.
So the current symfind will find that address 0045bd20 belongs to s0
instead of s1.

If translation block is interrupted by e.g. mmu exception
we need to compute conditional flags for inclusion into
saved cpu state. Otherwise after return from trap
conditional instructions would use stale psr/xcc data.

Once again, the emulation of the EERD and ICS registers in e1000.c is
incorrect. Nobody has noticed this before because none of the Intel-written
e1000 drivers use these registers, and all of the independently written open
source drivers copy Intel's example, so they don't use them either.
Regardless, these registers are documented in the programmer's manuals, and
their emulated behavior doesn't match the verified behavior of real hardware,
so any software that does use them doesn't function correctly.

When a VM state change handler changes VM state, other VM state change
handlers can see the state transitions out of order.
bmdma_map(), scsi_disk_init() and virtio_blk_init() install VM state
change handlers to restart DMA. These handlers can vm_stop() by
running into a write error on a drive with werror=stop. This throws
the VM state change handler callback into disarray. Here's an example
case I observed:
0. The virtual IDE drive goes south. All future writes return errors.
1. Something encounters a write error, and duly stops the VM with
vm_stop().
2. vm_stop() calls vm_state_notify(0).
3. vm_state_notify() runs the callbacks in list vm_change_state_head.
It contains ide_dma_restart_cb() installed by bmdma_map(). It also
contains audio_vm_change_state_handler() installed by audio_init().
4. audio_vm_change_state_handler() stops audio stuff.
5. User continues VM with monitor command "c". This runs vm_start().
6. vm_start() calls vm_state_notify(1).
7. vm_state_notify() runs the callbacks in vm_change_state_head.
8. ide_dma_restart_cb() happens to come first. It does its work, runs
into a write error, and duly stops the VM with vm_stop().
9. vm_stop() runs vm_state_notify(0).
10. vm_state_notify() runs the callbacks in vm_change_state_head.
11. audio_vm_change_state_handler() stops audio stuff. Which isn't
running.
12. vm_stop() finishes, ide_dma_restart_cb() finishes, step 7's
vm_state_notify() resumes running handlers.
13. audio_vm_change_state_handler() starts audio stuff. Oopsie.
Fix this by moving the actual write from each VM state change handler
into a new bottom half (suggested by Gleb Natapov).

Conditional moves off fp condition codes were using the result of
get_fp_bit to isolate and test the relevant condition code. However,
get_fp_bit returns the bit number of the condition code, not a
bitmask. (Compare the use of get_fp_bit in gen_compute_branch1, for
instance.)
Fixed by shifting a bitmask into place using the result of get_fp_bit in
the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).

The pc-0.11 type allows users of qemu-0.11 to use a machine type which
they know will remain compatible when the upgrade to qemu-0.12.
Management tools may choose to canonicalize the 'pc' machine type to
'pc-0.11' so that if the 'pc' alias changes target in future versions
of qemu, the machine type used will remain compatible.

Add an 'alias' field to QEMUMachine and display it in the output of
'qemu -M ?' with an '(aliased to foo)' suffix.
Aliases can change targets in newer versions of qemu, so management tools
may choose canonicalize machine types to ensure that if a user chooses an
alias, that the actual machine type used will remain compatible in
future.
This is intended to mimic a symlink to a machine description file.

This allows a program to initialize a host networking device using a
file descriptor passed over a unix monitor socket.
The program must first pass the file descriptor using SCM_RIGHTS
ancillary data with the getfd monitor command. It then may do
"host_net_add tap fd=name" to use the named file descriptor.

closefd allows passed file descriptors to be closed. If a monitor

required.

This patch addresses the problems found by Andriy Gapon:
- The code was incorrectly overwriting the high order 32
bits of the timer and hpet config registers. This didn't show up
in testing because linux and windows use hpet in legacy mode,
where the high order 32 bits (advertising available interrupts)
of the timer config register are ignored, and the high order 32
bits of the hpet config register are reserved and unused.
- The mask for level-triggered interrupts was off by a bit. (hpet
doesn't currently support level-triggered interrupts).
In addition, I removed some unused #defines, and corrected the ioapic
interrupt values advertised. I'd set this up early in hpet development
and never went back to correct it, and no bugs resulted since linux and
windows use hpet in legacy mode where available interrupts are ignored.

Instead of storing the backing file in its own BlockDriverState, VMDK uses the
BlockDriverState of the raw image file it opened. This is wrong and breaks
functions that access the backing file or protocols. This fix replaces all

This fixes qemu-iotests failure in 020 (Commit changes to backing file).
