md/raid10: fix problem with on-stack allocation of r10bio structure.
md: Don't truncate size at 4TB for RAID0 and Linear
This patch fixes a regression bug with the handling of zero-length
data CDBs within transport_generic_new_cmd() code. The bug was introduced
with the following commit as part of the single task conversion work:
commit 4101f0a89d
Author: Christoph Hellwig <hch@infradead.org>
Date: Tue Apr 24 00:25:03 2012 -0400
target: always allocate a single task
where the zero-length check for SCF_SCSI_DATA_SG_IO_CDB was incorrectly
changed to SCF_SCSI_CONTROL_SG_IO_CDB because of the seperate comment
in transport_generic_new_cmd() wrt to control CDBs zero-length handling
introduced in:
commit 91ec1d3535
Author: Nicholas Bellinger <nab@linux-iscsi.org>
Date: Fri Jan 13 12:01:34 2012 -0800
target: Add workaround for zero-length control CDB handling
So go ahead and change transport_generic_new_cmd() to handle control+data
zero-length CDBs in the same manner for this special case.
Tested with iscsi-target + loopback fabric port LUNs on 3.6-rc0 code.
This patch will also need to be picked up for 3.5-stable.
(hch: Add proper comment in transport_generic_new_cmd)

A 'struct r10bio' has an array of per-copy information at the end.
This array is declared with size [0] and r10bio_pool_alloc allocates
enough extra space to store the per-copy information depending on the
number of copies needed.
So declaring a 'struct r10bio on the stack isn't going to work. It
won't allocate enough space, and memory corruption will ensue.
So in the two places where this is done, declare a sufficiently large
structure and use that instead.
The two call-sites of this bug were introduced in 3.4 and 3.5
so this is suitable for both those kernels. The patch will have to
be modified for 3.4 as it only has one bug.

If the user bit is set, that mean BIOS can't set and record the wlan
status, it will report the value read from id ASUS_WMI_DEVID_WLAN_LED
(0x00010012) while we query the wlan status by id ASUS_WMI_DEVID_WLAN
(0x00010011) through WMI.
So, we have to record wlan status in id ASUS_WMI_DEVID_WLAN_LED
(0x00010012) while setting the wlan status through WMI.
This is also the behavior that windows app will do.
Quote from ASUS application engineer
===
When you call WMIMethod(DSTS, 0x00010011) to get WLAN status, it may return
(1) 0x00050001 (On)
(2) 0x00050000 (Off)
(3) 0x00030001 (On)
(4) 0x00030000 (Off)
(5) 0x00000002 (Unknown)
(1), (2) means that the model has hardware GPIO for WLAN, you can call
WMIMethod(DEVS, 0x00010011, 1 or 0) to turn WLAN on/off.
(3), (4) means that the model doesn’t have hardware GPIO, you need to use
API or driver library to turn WLAN on/off, and call
WMIMethod(DEVS, 0x00010012, 1 or 0) to set WLAN LED status.
After you set WLAN LED status, you can see the WLAN status is changed with
WMIMethod(DSTS, 0x00010011). Because the status is recorded lastly
(ex: Windows), you can use it for synchronization.
(5) means that the model doesn’t have WLAN device.
WLAN is the ONLY special case with upper rule.
For other device, like Bluetooth, you just need use
WMIMethod(DSTS, 0x00010013) to get, and WMIMethod(DEVS, 0x00010013, 1 or 0)
to set.

The cache_type file in sysfs lets users configure the disk cache in
write-through or write-back modes. However, ata disks do not support
writing to the file because they do not implement the MODE SELECT
command.
This patch adds a translation from MODE SELECT (for the caching page
only) to the ATA SET FEATURES command. The set of changeable parameters
answered by MODE SENSE is also adjusted accordingly.

Since the next patch will introduce support for MODE SELECT, it
makes sense to start advertising which bits are actually changeable.
For now, the answer is none.
Default parameters can also be reported, they are simply the same
as the current parameters.

Some other unlikely() should probably be removed as well. A fresh look
reveals an over-enthusiasm for unlikely() in libata-scsi.c.

Currently, SATA disk fua detection is disabled on default because most of
devices don't support this feature at that time. With the development of
technology, more and more SATA disks support this feature. So now we can enable
this detection on default.
Although fua detection is defined as a kernel module parameter, it is too hard
to set its value because it must be loaded and set before system starts up.
That needs to modify initrd file. So it is inconvenient for administrator who
needs to manage a huge number of servers.

A driver or app may repeatedly request a wakeup source while the system
is attempting to enter suspend, which may indicate a bug or at least
point out a highly active system component that is responsible for
decreased battery life on a mobile device. Even when the incidence
of suspend abort is not severe, identifying wakeup sources that
frequently abort suspend can be a useful clue for power management
analysis.
In some cases the existing stats can point out the offender where there is
an unexpectedly high activation count that stands out from the others, but
in other cases the wakeup source frequently taken just after the rest of
the system thinks its time to suspend might not stand out in the overall
stats.
It is also often useful to have information about what's been happening
recently, rather than totals of all activity for the system boot.
It's suggested to dump a line about which wakeup source
aborted suspend to aid analysis of these situations.
