xz_dec_run() could incorrectly return XZ_BUF_ERROR if all of the
following was true:

 - The caller knows how many bytes of output to expect and only provides
   that much output space.

 - When the last output bytes are decoded, the caller-provided input
   buffer ends right before the LZMA2 end of payload marker.  So LZMA2
   won't provide more output anymore, but it won't know it yet and thus
   won't return XZ_STREAM_END yet.

 - A BCJ filter is in use and it hasn't left any unfiltered bytes in the
   temp buffer.  This can happen with any BCJ filter, but in practice
   it's more likely with filters other than the x86 BCJ.

This fixes <https://bugzilla.redhat.com/show_bug.cgi?id=735408> where
Squashfs thinks that a valid file system is corrupt.

This also fixes a similar bug in single-call mode where the uncompressed
size of a block using BCJ + LZMA2 was 0 bytes and caller provided no
output space.  Many empty .xz files don't contain any blocks and thus
don't trigger this bug.

This also tweaks a closely related detail: xz_dec_bcj_run() could call
xz_dec_lzma2_run() to decode into temp buffer when it was known to be
useless.  This was harmless although it wasted a minuscule number of CPU
cycles.

This is modeled after the smaps code.

It detects transparent hugepages and then does a single gather_stats()

We need to teach the numa_maps code about transparent huge pages.  The
first step is to teach gather_stats() that the pte it is dealing with
might represent more than one page.

Note that will we use this in a moment for transparent huge pages since
they have use a single pmd_t which _acts_ as a "surrogate" for a bunch
of smaller pte_t's.

I'm a _bit_ unhappy that this interface counts in hugetlbfs page sizes
for hugetlbfs pages and PAGE_SIZE for normal pages.  That means that to
figure out how many _bytes_ "dirty=1" means, you must first know the
hugetlbfs page size.  That's easier said than done especially if you
don't have visibility in to the mount.

But, that's probably a discussion for another day especially since it
would change behavior to fix it.  But, just in case anyone wonders why
this patch only passes a '1' in the hugetlb case...

When asyncronous crypto algorithms are used, there might be many
packets that passed the xfrm replay check, but the replay advance
function is not called yet for these packets. So the replay check
function would accept a replay of all of these packets. Also the
system might crash if there are more packets in async processing
than the size of the anti replay window, because the replay advance
function would try to update the replay window beyond the bounds.

This pach adds a second replay check after resuming from the async
processing to fix these issues.

  # cd /cgroup
  # echo "8:0 1000" > blkio.throttle.read_bps_device
  # unplug the device
  # cat blkio.throttle.read_bps_device
  8:0	1000

It seems that at least one PPC machine would occasionally give a (valid) 0 as
the return value from dma_map, this caused the ixgbe code to not work
correctly.  A fix is pending in the PPC tree to not return 0 from dma map, but
we can also fix the driver to make sure we don't mess up in other arches as
well.

This patch is applicable to all current stable kernels.

"ARM: set vga memory base at run-time"

Makes the Integrator/AP freeze completely. I appears that
this is due to the VGA base address being assigned at PCI
init time, while this base is needed earlier than that.
Moving the initialization of the base address to the
.map_io function solves this problem.

When using MLPPP, the maximum size of a fragment is incorrectly
calculated with an offset of -2.
This patch reverses the changes in the patch found here:
http://marc.info/?l=linux-netdev&m=123541324010539&w=2

The value of hdrlen includes the size of both the 2-byte PPP protocol
field and the 2- or 4-byte multilink header (2+4=6 for long sequence
numbers, 2+2=4 for short sequence numbers). Section 2 of RFC1661 says
that the MRU that is negotiated (i.e., the MTU of the sending system)
includes only the PPP payload but not the protocol field, thus the
correct MTU should be the link's MTU minus the multilink header (mtu -
(hdrlen-2)).

The incorrect calculation causes Linux to fragment packets to a size two
bytes smaller than the allowed MTU. While not technically illegal, this
behaviour confounds MRU-tuning to avoid PPP-layer fragmentation.
