It is possible, that shutdown on target occurs earlier than migration
finish. In this case we crash in bdrv_release_dirty_bitmap_locked()
on assertion "assert(!bdrv_dirty_bitmap_busy(bitmap));" as we do have
busy bitmap, as bitmap migration is ongoing.
We'll fix bitmap migration to gracefully cancel on early shutdown soon.
Now let's fix iotest 194 to wait migration completion before shutdown.
Note that in this test dest_vm.shutdown() is called implicitly, as vms
used as context-providers, see __exit__() method of QEMUMachine class.
Actually, not waiting migration finish is a wrong thing, but the test
started to crash after commit ae00aa2398
"iotests: 194: test also migration of dirty bitmap", which added dirty
bitmaps here. So, Fixes: tag won't hurt.

The Plug & Play region of the AHB/APB bridge can be accessed
by various word size, however the implementation is clearly
restricted to 32-bit:
static uint64_t grlib_ahb_pnp_read(void *opaque, hwaddr offset, unsigned size)
{
AHBPnp *ahb_pnp = GRLIB_AHB_PNP(opaque);
return ahb_pnp->regs[offset >> 2];
}
Similarly to commit 0fbe394a64 with the APB PnP registers,
set the MemoryRegionOps::impl min/max fields to 32-bit, so
memory.c::access_with_adjusted_size() can adjust when the
access is not 32-bit.

Fixes: https://bugs.launchpad.net/bugs/1876373
This code path in mmap occurs when a page size is decreased with mremap. When a section of pages is shrunk, qemu calls mmap_reserve on the pages that were released. However, it has the diff operation reversed, subtracting the larger old_size from the smaller new_size. Instead, it should be subtracting the smaller new_size from the larger old_size. You can also see in the previous line of the change that this mmap_reserve call only occurs when old_size > new_size.

Convert the insns in the one-register-and-immediate group to decodetree.
In the new decode, our asimd_imm_const() function returns a 64-bit value
rather than a 32-bit one, which means we don't need to treat cmode=14 op=1
as a special case in the decoder (it is the only encoding where the two
halves of the 64-bit value are different).
