When the last subscriber to a "Through" port has been removed, the
subscribed destination ports might still be active, so it would be
wrong to send "all sounds off" and "reset controller" events to them.
The proper place for such a shutdown would be the closing of the actual
MIDI port (and close_substream() in rawmidi.c already can do this).
This also fixes a deadlock when dummy_unuse() tries to send events to
its own port that is already locked because it is being freed.

iommu_map() calls trace_map() with iova and size. trace_map()
should report original iova and original size as opposed to
iova and size after they get changed during mapping. size is
always zero at the end of mapping which is useless to report
and iova as it gets incremented, it is not as useful as the
original iova. Change iommu_map() to call trace_map() to
report original iova and original size.

This patch implements an I2C bus sharing mechanism between the host and platform
hardware on select Intel BayTrail SoC platforms using the X-Powers AXP288 PMIC.
On these platforms access to the PMIC must be shared with platform hardware. The
hardware unit assumes full control of the I2C bus and the host must request
access through a special semaphore. Hardware control of the bus also makes it
necessary to disable runtime pm to avoid interfering with hardware transactions.

ARPL and MOVSXD are encoded the same and their execution depends on the
execution mode. The operand sizes of each instruction are different.
Currently, ARPL is detected too late, after the decoding was already done, and
therefore may result in spurious exception (instead of failed emulation).
Introduce a group to the emulator to handle instructions according to execution
mode (32/64 bits). Note: in order not to make changes that may affect
performance, the new ModeDual can only be applied to instructions with ModRM.

Indeed, Intel SDM specifically states that for the RET instruction "In 64-bit
mode, the default operation size of this instruction is the stack-address size,
i.e. 64 bits."
However, experiments show this is not the case. Here is for example objdump of
small 64-bit asm:
4004f1: ca 14 00 lret $0x14
4004f4: 48 cb lretq
4004f6: 48 ca 14 00 lretq $0x14
Therefore, remove the Stack flag from far-ret instructions.

During a recent cleanup of the arm64 DTs it has become clear that
the handling of PPIs in xxxx_set_type() is incorrect. The ARM TRMs
for GICv2 and later allow for "implementation defined" support for
setting the edge or level type of the PPI interrupts and don't restrict
the activation level of the signal. Current ARM implementations
do restrict the PPI level type to IRQ_TYPE_LEVEL_LOW, but licensees
of the IP can decide to shoot themselves in the foot at any time.

When an interrupt occurs __gic_irq_dispatch() continuously reads local
and shared pending registers until all is serviced before
returning. The problem with that is that it could introduce a long
delay before returning if a piece of hardware keeps triggering while
in one of these loops.
To ensure fairness and priority doesn't get skewed a lot, read local
and shared pending registers once to service each pending IRQ once.
If another interupt triggers while servicing the current ones, then we
shall re-enter the handler after we return.
