Small change (mostly formatting) to limit lookup based open calls to
file create only.
After discussion yesteday on samba-technical about the posix lookup
regression, and looking at a problem with cifs posix open to one
particular Samba version, Jeff and JRA realized that Samba server's
behavior changed in this area (posix open behavior on files vs.
directories). To make this behavior consistent, JRA just made a
fix to Samba server to alter how it handles open of directories (now
returning the equivalent of EISDIR instead of success). Since we don't
know at lookup time whether the inode is a directory or file (and
thus whether posix open will succeed with most current Samba server),
this change avoids the posix open code on lookup open (just issues
posix open on creates). This gets the semantic benefits we want
(atomicity, posix byte range locks, improved write semantics on newly
created files) and file create still is fast, and we avoid the problem
that Jeff noticed yesterday with "openat" (and some open directory
calls) of non-cached directories to one version of Samba server, and
will work with future Samba versions (which include the fix jra just
pushed into Samba server). I confirmed this approach with jra
yesterday and with Shirish today.
Posix open is only called (at lookup time) for file create now.
For opens (rather than creates), because we do not know if it
is a file or directory yet, and current Samba no longer allows
us to do posix open on dirs, we could end up wasting an open call
on what turns out to be a dir. For file opens, we wait to call posix
open till cifs_open. It could be added here (lookup) in the future
but the performance tradeoff of the extra network request when EISDIR
or EACCES is returned would have to be weighed against the 50%
reduction in network traffic in the other paths.

Previously, we would set the control bus switch before calls were made
to request EDID information over DDC. But recently the DDC code started
doing multiple I2C transfers to get the EDID extensions as well. This
tripped up SDVO, because the control bus switch is only in effect until
the next STOP after a START. By doing our own algo, we can wrap each i2c
transaction on the DDC I2C bus with the control bus switch it requires.

drm_connector_init sets both the connector type and the connector type_id
on the newly initialised connector. As the connector type_id is coupled to
the connector type, the connector type cannot simply be modified on an
initialised connector.
This patch changes the order of operations on intel_sdvo_init so that the
type is determined before the connector is intialised.
This fixes a bug whereby the name card0-VGA-1 would be allocted to both a
CRT and an SDVO connector since the SDVO connector would be initialised
with type 'unknown' and hence have its type_id assigned from the wrong pool.

Remove ACPI 3 E820 extended memory attributes support. At least one
vendor actively set all the flags to zero, but left ECX on return at
24. This bug may be present in other BIOSes.
The breakage functionally means the ACPI 3 flags are probably
completely useless, and that no OS any time soon is going to rely on
their existence. Therefore, drop support completely. We may want to
revisit this question in the future, if we find ourselves actually
needing the flags.
This reverts all or part of the following checkins:
cd670599b7c549e71d07
However, retain the part from the latter commit that copies e820 into
a temporary buffer; that is an unrelated BIOS workaround. Put in a
comment to explain that part.

It is possible for ide-cd to ignore ide_error()'s return value under

Since 2.6.26 we support UDMA66 on ATAPI devices requiring IVB quirk:
commit 8588a2b732
("ide: add SH-S202J to ivb_list[]")
We also later added support for more such devices in:
commit e97564f362
("ide: More TSST drives with broken cable detection")
and in:
commit 3ced5c49bd
("ide: add TSSTcorp CDDVDW SH-S202H to ivb_list[]")
It turns out that such devices lack cable detection altogether
(which in turn results in incorrect detection of 40-wire cables
by our current cable detection strategy) so always handle them
by trusting host-side cable detection only.

When the i2400m is connected to a network, the host interface (USB)
cannot be suspended. For that to happen, the device has to have
negotiated with the basestation to put the link on IDLE state.
If the host tries to put the device in standby while it is connected
but not idle, the device resets, as the driver should not do that.
To avoid triggering that, when the USB susbsytem requires the driver
to autosuspend the device, the driver checks if the device is not yet
idle. If it is not, the request is rejected (will be retried again
later on after the autosuspend timeout). At some point the device will
enter idle and the request will succeed (unless of course, there is
network traffic, but at that point, there is no idle neither in the
link or the host interface).
