Except for round-robin TCG, every other accelerator is using more or
less the same code around qemu_wait_io_event_common. The exception
is HAX, which also has to eat the dummy APC that is queued by
qemu_cpu_kick_thread.
We can add the SleepEx call to qemu_wait_io_event under "if
(!tcg_enabled())", since that is the condition that is used in
qemu_cpu_kick_thread, and unify the function for KVM, HAX, HVF and
multi-threaded TCG. Single-threaded TCG code can also be simplified
since it is only used in the round-robin, sleep-if-all-CPUs-idle case.

This patch adds saving and restoring of the icount warp
timers in the vmstate.
It is needed because there timers affect the virtual clock value.
Therefore determinism of the execution in icount record/replay mode
depends on determinism of the timers.

x86_update_hflags reference env->efer which is updated in hax_get_msrs,
so it has to be called after hax_get_msrs. This fix the bug that sometimes
dump_state show 32 bits regs even in 64 bits mode.

scsi_write_same_complete() can retry the write if the request was
unaligned. Make sure to release the AioContext when that code path is
taken!
This patch fixes a hang when QEMU terminates after an unaligned WRITE
SAME request has been processed with dataplane. The hang occurs because
iothread_stop_all() cannot acquire the AioContext lock that was leaked
by the IOThread in scsi_write_same_complete().
Fixes: b9e413dd37 ("block: explicitly acquire aiocontext in aio callbacks that need it").

Since omap_mmc is still using the legacy SD card API, the SD
card created by sd_init() is not plugged into any bus. This
means that the controller has to reset it manually.
Failing to do this mostly didn't affect the guest since the
guest typically does a programmed SD card reset as part of
its SD controller driver initialization, but would mean that
migration fails because it's only in sd_reset() that we
set up the wpgrps_size field.

In the case of sd-ssi, we have to implement an entire
reset function since there wasn't one previously, and
that requires a QOM cast macro that got omitted when this
device was QOMified.

Instead of ignoring the response from address_space_ld*()
(indicating an attempt to read a page table descriptor from
an invalid physical address), use it to report the failure
correctly.
Since this is another couple of locations where we need to
decide the value of the ARMMMUFaultInfo ea bit based on a
MemTxResult, we factor out that operation into a helper
function.

For PMSAv7, the v7A/R Arm ARM defines that setting AP to 0b111
is an UNPREDICTABLE reserved combination. However, for v7M
this value is documented as having the same behaviour as 0b110:
read-only for both privileged and unprivileged. Accept this
value on an M profile core rather than treating it as a guest
error and a no-access page.

This patch only moved the last part of migration_thread() into a new
function migration_iteration_finish() to make it much shorter. With
previous works to remove some local variables, now it's fairly easy to
do that.
