Henrique de Moraes Holschuh a50245af78 thinkpad-acpi: handle HKEY 0x4010, 0x4011 events
Handle events 0x4010 and 0x4011 so that we do not pester users about them.

These events report when the thinkpad is docked/undocked to a native
hotplug dock (i.e. one that does not need ACPI handling, nor is represented
in the ACPI device tree).  Such docks are based on USB 2.0/3.0, and also
work as port replicators.

We really want a proper dock class to report these, or at least new input
EV_SW events.  Since it is not clear which one to use yet, keep reporting
them as vendor-specific ThinkPad events.

WARNING: As defined by the thinkpad-acpi sysfs ABI rules of engagement, the
vendor-specific events will be REMOVED as soon as generic events are made
available (duplicate events are a big problem), with an appropriate update
to the thinkpad-acpi sysfs/event ABI versioning.  Userspace is already
prepared to provide easy backwards compatibility for such changes when
convenient to the distro (see acpi-fakekey).

* Event 0x4010: docking to hotplug dock/port replicator
* Event 0x4011: undocking from hotplug dock/port replicator

Typical usecase would be to trigger display reconfiguration.

Reports mention T410, T510, and series 3 docks/port replicators.  Special
thanks to Robert de Rooy for his extensive report and analysis of the
situation.

Henrique de Moraes Holschuh 2d43f671c8 thinkpad-acpi: handle some new HKEY 0x60xx events
Handle some user interface events from the newer Lenovo models.  We are likely
to do something smart with these events in the future, for now, hide the ones
we are already certain about from the user and userspace both.

* Events 0x6000 and 0x6005 are key-related.  0x6005 is not properly identified
  yet.  Ignore these events, and do not report them.

* Event 0x6040 has not been properly identified yet, and we don't know if it
  is important (looks like it isn't, but still...).  Keep reporting it.

* Change the message the driver outputs on unknown 0x6xxx events, as all
  recent events are not related to thermal alarms.  Degrade log level from
  ALERT to WARNING.

Thanks to all users who reported these events or asked about them in a number
of mailing lists.  Your help is highly appreciated, even if I did took a lot of
time to act on them.  For that I apologise.

I will list those that identified the reasons for the events as "reported-by",
and I apologise in advance if I leave anyone out: it was not done on purpose, I
made the mistake of not properly tagging all event report emails separately,
and might have missed some.

Matthew Garrett f70e957cda x86: Don't use the EFI reboot method by default
Testing suggests that at least some Lenovos and some Intels will
fail to reboot via EFI, attempting to jump to an unmapped
physical address. In the long run we could handle this by
providing a page table with a 1:1 mapping of physical addresses,
but for now it's probably just easier to assume that ACPI or
legacy methods will be present and reboot via those.

One could argue that the driver should unset DRIVER_MODESET in this case,

Eric Dumazet f03d78db65 net: refine {udp|tcp|sctp}_mem limits
Current tcp/udp/sctp global memory limits are not taking into account
hugepages allocations, and allow 50% of ram to be used by buffers of a
single protocol [ not counting space used by sockets / inodes ...]

Lets use nr_free_buffer_pages() and allow a default of 1/8 of kernel ram
per protocol, and a minimum of 128 pages.
Heavy duty machines sysadmins probably need to tweak limits anyway.

Kees Cook 7a3136666b x86, suspend: Restore MISC_ENABLE MSR in realmode wakeup
Some BIOSes will reset the Intel MISC_ENABLE MSR (specifically the
XD_DISABLE bit) when resuming from S3, which can interact poorly with
ebba638ae7. In 32bit PAE mode, this can
lead to a fault when EFER is restored by the kernel wakeup routines,
due to it setting the NX bit for a CPU that (thanks to the BIOS reset)
now incorrectly thinks it lacks the NX feature. (64bit is not affected
because it uses a common CPU bring-up that specifically handles the
XD_DISABLE bit.)

The need for MISC_ENABLE being restored so early is specific to the S3
resume path. Normally, MISC_ENABLE is saved in save_processor_state(),
but this happens after the resume header is created, so just reproduce
the logic here. (acpi_suspend_lowlevel() creates the header, calls
do_suspend_lowlevel, which calls save_processor_state(), so the saved
processor context isn't available during resume header creation.)

Dave Chinner 1316d4da3f xfs: unpin stale inodes directly in IOP_COMMITTED
When inodes are marked stale in a transaction, they are treated
specially when the inode log item is being inserted into the AIL.
It tries to avoid moving the log item forward in the AIL due to a
race condition with the writing the underlying buffer back to disk.
The was "fixed" in commit de25c18 ("xfs: avoid moving stale inodes
in the AIL").

To avoid moving the item forward, we return a LSN smaller than the
commit_lsn of the completing transaction, thereby trying to trick
the commit code into not moving the inode forward at all. I'm not
sure this ever worked as intended - it assumes the inode is already
in the AIL, but I don't think the returned LSN would have been small
enough to prevent moving the inode. It appears that the reason it
worked is that the lower LSN of the inodes meant they were inserted
into the AIL and flushed before the inode buffer (which was moved to
the commit_lsn of the transaction).

The big problem is that with delayed logging, the returning of the
different LSN means insertion takes the slow, non-bulk path.  Worse
yet is that insertion is to a position -before- the commit_lsn so it
is doing a AIL traversal on every insertion, and has to walk over
all the items that have already been inserted into the AIL. It's
expensive.

To compound the matter further, with delayed logging inodes are
likely to go from clean to stale in a single checkpoint, which means
they aren't even in the AIL at all when we come across them at AIL
insertion time. Hence these were all getting inserted into the AIL
when they simply do not need to be as inodes marked XFS_ISTALE are
never written back.

Transactional/recovery integrity is maintained in this case by the
other items in the unlink transaction that were modified (e.g. the
AGI btree blocks) and committed in the same checkpoint.

So to fix this, simply unpin the stale inodes directly in
xfs_inode_item_committed() and return -1 to indicate that the AIL
insertion code does not need to do any further processing of these
inodes.

Will Deacon 38a8914f9a ARM: 6987/1: l2x0: fix disabling function to avoid deadlock
The l2x0_disable function attempts to writel with the l2x0_lock held.
This results in deadlock when the writel contains an outer_sync call
for the platform since the l2x0_lock is already held by the disable
function. A further problem is that disabling the L2 without flushing it
first can lead to the spin_lock operation becoming visible after the
spin_unlock, causing any subsequent L2 maintenance to deadlock.

This patch replaces the writel with a call to writel_relaxed in the
disabling code and adds a flush before disabling in the control
register, preventing livelock from occurring.

Rafael J. Wysocki 4d4cf23cdd PM / Hibernate: Fix free_unnecessary_pages()
There is a bug in free_unnecessary_pages() that causes it to
attempt to free too many pages in some cases, which triggers the
BUG_ON() in memory_bm_clear_bit() for copy_bm.  Namely, if
count_data_pages() is initially greater than alloc_normal, we get
to_free_normal equal to 0 and "save" greater from 0.  In that case,
if the sum of "save" and count_highmem_pages() is greater than
alloc_highmem, we subtract a positive number from to_free_normal.
Hence, since to_free_normal was 0 before the subtraction and is
an unsigned int, the result is converted to a huge positive number
that is used as the number of pages to free.

Fix this bug by checking if to_free_normal is actually greater
than or equal to the number we're going to subtract from it.

Miklos Szeredi a51cb91d81 fs: fix lock initialization
locks_alloc_lock() assumed that the allocated struct file_lock is
already initialized to zero members.  This is only true for the first
allocation of the structure, after reuse some of the members will have
random values.

This will for example result in passing random fl_start values to
userspace in fuse for FL_FLOCK locks, which is an information leak at
best.

Fix by reinitializing those members which may be non-zero after freeing.

Padmavathi Venna 3075741417 spi/s3c64xx: Bug fix for SPI with different FIFO level
The existing macro fails for following scenarios.
1) S5P64X0 channel 1
2) S5PV210 channel 1

The FIFO data level supported in the above SoCs either 64 or
256 bytes depending on the channel. Because of this the TX_DONE
is the 25 bit in the status register.

The existing macro works for the following scenarios
1) S3C6410 all channels
2) S5PC100 all channels

The FIFO data level supported in the above SoCs 64 bytes
on all the channels. Because of this the TX_DONE is the 21 bit
in the status register.

So when we use the existing macro for the non-working SoCs
it is not anding with the TX_DONE bit for transmission status check.

Shreyas Bhatewara 5318d809d7 vmxnet3: fix starving rx ring whenoc_skb kb fails
If the rx ring is completely empty, then the device may never fire an rx
interrupt. Unfortunately, the rx interrupt is what triggers populating the
rx ring with fresh buffers, so this will cause networking to lock up.

This patch replenishes the skb in recv descriptor as soon as it is
peeled off while processing rx completions. If the skb/buffer
allocation fails, existing one is recycled and the packet in hand is
dropped. This way none of the RX desc is ever left empty, thus avoiding
starvation

Herbert Xu 44661462ee bridge: Always flood broadcast packets
As is_multicast_ether_addr returns true on broadcast packets as
well, we need to explicitly exclude broadcast packets so that
they're always flooded.  This wasn't an issue before as broadcast
packets were considered to be an unregistered multicast group,
which were always flooded.  However, as we now only flood such
packets to router ports, this is no longer acceptable.
