[SCSI] mpt3sas: Added a driver module parameter max_msix_vectors

Added a driver module parameter max_msix_vectors. Using this module parameter
the maximum number of MSI-X vectors could be set.

The number of MSI-X vectors used would be the minimum of MSI-X vectors
supported by the HBA, the number of CPU cores and the value set to
max_msix_vectors module parameter.

The default value of this module parameter is set to 8. The default value of
this parameter is set to 8 inorder to reduce the amount of memory required for
Reply Descriptor Post queue.  This is because with the higher MSI-X vectors,
some times kernel is not able to allocate the requested amount of memory and
crash is observed. To overcome this problem, the default value is set to 8.

[SCSI] mpt2sas: Fix for kernel panic when driver loads with HBA connected to non LUN 0 configured expander

With some enclosures when LUN 0 is not created but LUN 1 or LUN X is created
then SCSI scan procedure calls target_alloc, slave_alloc call back functions
for LUN 0 and slave_destory() for same LUN 0.

In these kind of cases within slave_destroy, pointer to scsi_target in
_sas_device structure is set to NULL, following which when slave_alloc for
LUN 1 is called then starget would not be set properly for this LUN.
So, scsi_target pointer pointing to NULL value would lead to a crash later
in the discovery procedure.

To solve this issue set the sas_device's scsi_target pointer to scsi_device's
scsi_target if it is NULL earlier in slave_alloc callback function.

The code here is
 c->Header.ReplyQueue = smp_processor_id() % h->nreply_queues;

Since it is not critical that the code complete on the same processor,
but the cpu is a hint used in generating the ReplyQueue and will still work if
the cpu migrates or is preempted, it is safe to use the raw_smp_processor_id()
to surpress the false positve warning.

preallocated memory it can happen that a new job is enqueud before
the memory is freed. The allocation fails and the message

[SCSI] ufs: Add support for host assisted background operations

Background operations in the UFS device can be disabled by
the host to reduce the response latency of transfer requests.
Add support for enabling/disabling the background operations
during runtime suspend/resume of the device.

If the device is in critical need of BKOPS it will raise an
URGENT_BKOPS exception which should be handled by the host to
make sure the device performs as expected.

During bootup, the BKOPS is enabled in the device by default.
The disable of BKOPS is supported only when the driver supports
runtime suspend/resume operations as the runtime PM framework
provides a way to determine the device idleness and hence BKOPS
can be managed effectively. During runtime resume the BKOPS is
disabled to reduce latency and during runtime suspend the BKOPS
is enabled to allow device to carry out idle time BKOPS.

In some cases where the BKOPS is disabled during runtime resume
and due to continuous data transfers the runtime suspend is not
triggered, the BKOPS is enabled when the device raises a level-2

btrfs: don't loop on large offsets in readdir

When btrfs readdir() hits the last entry it sets the readdir offset to a
huge value to stop buggy apps from breaking when the same name is
returned by readdir() with concurrent rename()s.

But unconditionally setting the offset to INT_MAX causes readdir() to
loop returning any entries with offsets past INT_MAX.  It only takes a
few hours of constant file creation and removal to create entries past
INT_MAX.

So let's set the huge offset to LLONG_MAX if the last entry has already
overflowed 32bit loff_t.   Without large offsets behaviour is identical.
With large offsets 64bit apps will work and 32bit apps will be no more
broken than they currently are if they see large offsets.

Btrfs: make sure the backref walker catches all refs to our extent

Because we don't mess with the offset into the extent for compressed we will
properly find both extents for this case

[extent a][extent b][rest of extent a]

but because we already added a ref for the front half we won't add the inode
information for the second half.  This causes us to leak that memory and not
print out the other offset when we do logical-resolve.  So fix this by calling
ulist_add_merge and then add our eie to the existing entry if there is one.
With this patch we get both offsets out of logical-resolve.  With this and the
other 2 patches I've sent we now pass btrfs/276 on my vm with compress-force=lzo
set.  Thanks,

Btrfs: fix backref walking when we hit a compressed extent

If you do btrfs inspect-internal logical-resolve on a compressed extent that has
been partly overwritten it won't find anything.  This is because we try and
match the extent offset we've searched for based on the extent offset in the
data extent entry.  However this doesn't work for compressed extents because the
offsets are for the uncompressed size, not the compressed size.  So instead only
do this check if we are not compressed, that way we can get an actual entry for
the physical offset rather than nothing for compressed.  Thanks,

Btrfs: do not offset physical if we're compressed

xfstest btrfs/276 was freaking out on slower boxes partly because fiemap was
offsetting the physical based on the extent offset.  This is perfectly fine with
uncompressed extents, however the extent offset is into the uncompressed area,
not the compressed.  So we can return a physical value that isn't at all within
the area we have allocated on disk.  Fix this by returning the start of the
extent if it is compressed no matter what the offset.  Thanks,

Btrfs: fix a bug of snapshot-aware defrag to make it work on partial extents

For partial extents, snapshot-aware defrag does not work as expected,
since
a) we use the wrong logical offset to search for parents, which should be
   disk_bytenr + extent_offset, not just disk_bytenr,
b) 'offset' returned by the backref walking just refers to key.offset, not
   the 'offset' stored in btrfs_extent_data_ref which is
   (key.offset - extent_offset).

The reproducer:
$ mkfs.btrfs sda
$ mount sda /mnt
$ btrfs sub create /mnt/sub
$ for i in `seq 5 -1 1`; do dd if=/dev/zero of=/mnt/sub/foo bs=5k count=1 seek=$i conv=notrunc oflag=sync; done

$ sync; btrfs filesystem defrag /mnt/sub/foo;
$ umount /mnt
$ btrfs-debug-tree sda (Here we can check whether the defrag operation is snapshot-awared.

Pull ACPI and power management fixes from Rafael Wysocki:

 - ACPI-based memory hotplug stopped working after a recent change,
   because it's not possible to associate sufficiently many "physical"
   devices with one ACPI device object due to an artificial limit.  Fix
   from Rafael J Wysocki removes that limit and makes memory hotplug
   work again.

 - A change made in 3.9 uncovered a bug in the ACPI processor driver
   preventing NUMA nodes from being put offline due to an ordering
   issue.  Fix from Yasuaki Ishimatsu changes the ordering to make
   things work again.

 - One of the recent ACPI video commits (that hasn't been reverted so
   far) uncovered a bug in the code handling quirky BIOSes that caused
   some Asus machines to boot with backlight completely off which made
   it quite difficult to use them afterward.  Fix from Felipe Contreras
   improves the quirk to cover this particular case correctly.

 - A cpufreq user space interface change made in 3.10 inadvertently
   renamed the ignore_nice_load sysfs attribute to ignore_nice which
   resulted in some confusion.  Fix from Viresh Kumar changes the name
   back to ignore_nice_load.

 - An initialization ordering change made in 3.9 broke cpufreq on
   loongson2 boards.  Fix from Aaro Koskinen restores the correct
   initialization ordering there.

 - Fix breakage resulting from a mistake made in 3.9 and causing the
   detection of some graphics adapters (that were detected correctly
   before) to fail.  There are two objects representing the same PCIe
   port in the affected systems' ACPI tables and both appear as
   "enabled" and we are expected to guess which one to use.  We used to
   choose the right one before by pure luck, but when we tried to
   address another similar corner case, the luck went away.  This time
   we try to make our guessing a bit more educated which is reported to
   work on those systems.

 - The /proc/acpi/wakeup interface code is missing some locking which
   may lead to breakage if that file is written or read during hotplug
   of wakeup devices.  That should be rare but still possible, so it's
   better to start using the appropriate locking there.
