There is only one failure point: bdrv_change_backing_file in this
function, so we can drop the qlist and try to change the backing file
before deleting anything.
This way bdrv_drop_intermediate is simplified while keeping the
operation transactional. A bonus is dropping an active BDS is supported
There is errp passed in, so no need for local_err and error_propagate.

Hi,
I am also encountering the bug of high cpu usage for a windows guest after
suspend resume of my ubuntu host. Problem was in 13.04 but it's also still
there in 13.10.
The windows guest has virtio / spice enabled.
Linux guests do not get the high cpu usage.
Are there any more logs required
Hello Stefan,
The qemu used by me is the one installed using apt-get install qemu. The
executable is in /usr/bin. The KVM driver is the one supplied with Ubuntu 13.04.

All of these patches have been posted over the month of September.
This pull includes conversions of 4 of the tcg backends to the new
ldst opcodes. There are 2 more backends that I have also converted,
ia64 and sparc, but at present I'm not able to re-test those so I've
left them out.

No support for helpers with non-default endianness yet,
but good enough to test the opcodes.

Once we form a combined qemu_st_i32 opcode, we won't be able to
have separate constraints based on size. This one is fairly easy
to work around, since eax is available as a scratch register.
When storing variable data, this tends to merely exchange one mov
for another. E.g.
-: mov

If we pull the code to emit the actual load/store into a subroutine,
we can share the reg+reg addressing mode code between softmmu and
usermode. This lets us load GUEST_BASE into a temporary register
rather than attempting to add it piece-wise to the address.
Which lets us use movw+movt for

Or, partially. The fundamental primitives for the port are gen_load_mem
and gen_store_mem, which take a callback to emit the memory operation.
For that, we continue to use the original inline functions that forward
to the new ops, rather than replicate the same thing privately.
That said, all

Pass two TCGReg to tcg_out_tlb_load, rather than idx+args.
Move ldst_optimization routines just below tcg_out_tlb_load to avoid
the need for forward declarations.
Use TCGReg enum in preference to int where apprpriate.
