Sanity check the flags passed to change_mnt_propagation().  Exactly
one flag should be set.  Return EINVAL otherwise.

Userspace can pass in arbitrary combinations of MS_* flags to mount().
do_change_type() is called if any of MS_SHARED, MS_PRIVATE, MS_SLAVE,
or MS_UNBINDABLE is set.  do_change_type() clears MS_REC and then
calls change_mnt_propagation() with the rest of the user-supplied
flags.  change_mnt_propagation() clearly assumes only one flag is set
but do_change_type() does not check that this is true.  For example,
mount() with flags MS_SHARED | MS_RDONLY does not actually make the
mount shared or read-only but does clear MNT_UNBINDABLE.

Only fallback to a set of default modes on a connector iff that
connector is known to be connected. The issue occurs that with limited
hardware which cannot probe a connector and so reports the
connector status as unknown will then attempt to retrieve the modes for
it during drm_helper_probe_single_connector_modes(). Should that fail,
the helper then generates a default set which fools the fb_helper and
causes havoc with the console and beyond.

Polling for a VGA device on an old system can be quite expensive,
causing latencies on the order of 600ms. As we hold the mode mutex for
this time and also need the same mutex to move the cursor, we trigger a
user-visible stall.

The real solution would involve improving the granulatity of the
locking and so perhaps performing some of the probing not under the lock
or some other updates can be done under different locks. Also reducing the
cost of probing for a non-existent monitor would be worthwhile. However,
exposing a parameter to disable polling is a simple workaround in the
meantime.

In order to accommodate users turning polling on and off at runtime, the
polling is potentially re-enabled on every probe. This is coupled to
the user calling xrandr, which seems to be a vaild time to reset the
polling timeout since the information on the connection has just been
updated. (The presumption being that all connections are probed in a
single xrandr pass, which is currently valid.)

However, this code was later moved to asic specific functions

was not relevant for those asics.  So, remove it.

VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write
packet event codes for received PHY packets (or perhaps write
evt_no_status, hard to tell).  Work around it by overwriting the
packet's ACK by ack_complete, so that upper layers that listen to PHY
packet reception get to see these packets.

(Also tested:  TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643,
JMicron JMB381 --- these do not exhibit this bug.)

Clemens proposed a quirks flag for that, IOW whitelist known misbehaving
controllers for this workaround.  Though to me it seems harmless enough
to enable for all controllers.

The log_ar_at_event() debug log will continue to show the original
status from the DMA unit.
