Use the order of incoming RAMBlocks from the source to record
an index number; that then allows us to sort the destination
local RAMBlock list to match the source.

RDMA uses a hash from block offset->RAM Block; this isn't needed
on the destination, and now that the destination sorts the ramblock
list, is harder to maintain.
Split the hash so that it's only generated on the source.

The check "liobn & 0xULL" in spapr_tce_find_by_liobn()
is completely useless since liobn is only declared as an uint32_t

Hello,
I see a problem with input volume control on a Windows7 guest

the input volume from 0% to 1% under Windows results in
the "gain" values in the emulated HW to jump from 0 to 40 (out of 74)

Hi Zhu,
I installed and enabled the --iasl=IASL at "configuration" for
qemu and then "make" it.
When i tried to delete the cpu1 after adding it using hotplug/unplug, I am
facing the kernel panic at guest os. Kernel version
