the failure is most certainly because of out of memory.

pci: Add flag indicating device has been assigned by KVM

Device drivers that create and destroy SR-IOV virtual functions via
calls to pci_enable_sriov() and pci_disable_sriov can cause catastrophic
failures if they attempt to destroy VFs while they are assigned to

flag and avoid destroying VFs while they are assigned and avoid system

XZ: Fix incorrect XZ_BUF_ERROR

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.

ppp_generic: fix multilink fragment MTU calculation (again)

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.
