When reading from pstore there is a buffer overflow during decompression
due to the header added in unzip_oops. Remove unzip_oops and call
pstore_decompress directly in nvram_pstore_read. Allocate buffer of size
report_length of the oops header as header will not be deallocated in pstore.
Since we have 'openssl' command line tool to decompress the compressed data,
dump the compressed data in case decompression fails instead of not dumping
anything.

Commit 5688978 ("ext4: improve handling of conflicting mount options")
introduced incorrect messages shown while choosing wrong mount options.
First of all, both cases of incorrect mount options,
"data=journal,delalloc" and "data=journal,dioread_nolock" result in
the same error message.
Secondly, the problem above isn't solved for remount option: the
mismatched parameter is simply ignored. Moreover, ext4_msg states
that remount with options "data=journal,delalloc" succeeded, which is
not true.
To fix it up, I added a simple check after parse_options() call to
ensure that data=journal and delalloc/dioread_nolock parameters are
not present at the same time.

Commit 26092bf ("ext4: use a table-driven handler for mount options")
wrongly disallows the specifying the mount options nodelalloc and
data=journal simultaneously. This is incorrect; it should have only
disallowed the combination of delalloc and data=journal
simultaneously.

John W. Linville says:
====================
This is a batch of fixes intended for the 3.11 queue...
Regarding the mac80211 (and related) bits, Johannes says:
"I have a fix from Chris for an infinite loop along with fixes from
myself to prevent it entering the loop to start with (continue using
disabled channels, many thanks to Chris for his debug/test help) and a
workaround for broken APs that advertise a bad HT primary channel in
their beacons. Additionally, a fix for another attrbuf race in mac80211
and a fix to clean up properly while P2P GO interfaces go down."
Along with that...
Solomon Peachy corrects a range check in cw1200 that would lead to
a BUG_ON when starting AP mode.
Stanislaw Gruszka provides an iwl4965 patch to power-up the device
earlier (avoiding microcode errors), and another iwl4965 fix that
resets the firmware after turning rfkill off (resolving a bug in the
Red Hat Bugzilla).
Please let me know if there are problems!

In adt7470_write_word_data(), which writes two bytes using
i2c_smbus_write_byte_data(), the return codes are incorrectly AND-ed
together when they should be OR-ed together.
The return code of i2c_smbus_write_byte_data() is zero for success.
The upshot is only the first byte was ever written to the hardware.
The 2nd byte was never written out.
I noticed that trying to set the fan speed limits was not working
correctly on my system. Setting the fan speed limits is the only
code that uses adt7470_write_word_data(). After making the change
the limit settings work and the alarms work also.

This reverts commit 318df36e57c0ca9f2146660d41ff28e8650af423.
This commit caused Steven Rostedt's hackbench runs to run out of memory
due to a leak. As noted by Joonsoo Kim, it is buggy in the following
scenario:
"I guess, you may set 0 to all kmem caches's cpu_partial via sysfs,
doesn't it?
In this case, memory leak is possible in following case. Code flow of
possible leak is follwing case.
* in __slab_free()
1. (!new.inuse || !prior) && !was_frozen
2. !kmem_cache_debug && !prior
3. new.frozen = 1
4. after cmpxchg_double_slab, run the (!n) case with new.frozen=1
5. with this patch, put_cpu_partial() doesn't do anything,
because this cache's cpu_partial is 0
6. return
In step 5, leak occur"
And Steven does indeed have cpu_partial set to 0 due to RT testing.
Joonsoo is cooking up a patch, but everybody agrees that reverting this
for now is the right thing to do.

fixup for drm/i915: Add vma to list at creation
|
|
formerly: "drm/i915: Create VMAs (part 4) - Error capture"
Since the active/inactive lists are per VM, we need to modify the error
capture code to be aware of this, and also extend it to capture the
buffers from all the VMs. For now all the code assumes only 1 VM, but it
will become more generic over the next few patches.
NOTE: If the number of VMs in a real world system grows significantly
we'll have to focus on only capturing the guilty VM, or else it's likely
there won't be enough space for error capture.
v2: Squashed in the "part 6" which had dependencies on the mm_list
change. Since I've moved the mm_list change to an earlier point in the

formerly: "drm/i915: Create VMAs (part 5) - move mm_list"
The mm_list is used for the active/inactive LRUs. Since those LRUs are
per address space, the link should be per VMx .
Because we'll only ever have 1 VMA before this point, it's not incorrect
to defer this change until this point in the patch series, and doing it
here makes the change much easier to understand.
Shamelessly manipulated out of Daniel:
"active/inactive stuff is used by eviction when we run out of address
space, so needs to be per-vma and per-address space. Bound/unbound otoh
is used by the shrinker which only cares about the amount of memory used
and not one bit about in which address space this memory is all used in.
Of course to actual kick out an object we need to unbind it from every
address space, but for that we have the per-object list of vmas."

formerly: "drm/i915: Create VMAs (part 3.5) - map and fenceable

The map_and_fenceable tracking is per object. GTT mapping, and fences
only apply to global GTT. As such, object operations which are not
performed on the global GTT should not effect mappable or fenceable

Functionally, this commit could very well be squashed in to a previous

From CEA-861:
Data Byte 1, bit A0 indicates whether Active Format Data is present in
Data Byte 2 bits R3 through R0. A source device shall set A0=1 when
any of the AFD bits are set.
ie. if we want to set active_aspect, we need to set the
active_info_valid bit to 1 as well.

If the user if this API is providing a bigger buffer than the infoframe
size, it could be for a could reason. For instance it could be because
it gives the buffer that will be written to the hardware, up to the
maximum of an infoframe size.
Instead of just zeroing up to the infoframe size, let's zero the whole
incoming buffer as those extra bytes are also used to compute the
ECC and need to be 0.

And a way to pack hdmi_infoframe generically.
