      x86-32, fpu: Fix FPU exception handling on non-SSE systems · f994d99c
      Hans Rosenfeld authored 
      On 32bit systems without SSE (that is, they use FSAVE/FRSTOR for FPU
context switches), FPU exceptions in user mode cause Oopses, BUGs,
recursive faults and other nasty things:

This usually continues in slight variations until the system is reset.

      staging: usbip: bugfix for isochronous packets and optimization · 28276a28
      Arjan Mels authored 
      For isochronous packets the actual_length is the sum of the actual
length of each of the packets, however between the packets might be
padding, so it is not sufficient to just send the first actual_length
bytes of the buffer. To fix this and simultanesouly optimize the
bandwidth the content of the isochronous packets are send without the
padding, the padding is restored on the receiving end.

      staging: usbip: bugfix add number of packets for isochronous frames · 1325f85f
      Arjan Mels authored 
      The number_of_packets was not transmitted for RET_SUBMIT packets. The
linux client used the stored number_of_packet from the submitted
request. The windows userland client does not do this however and needs
to know the number_of_packets to determine the size of the transmission.

      staging: usbip: bugfixes related to kthread conversion · d2dd0b07
      Arjan Mels authored 
      When doing a usb port reset do a queued reset instead to prevent a
deadlock: the reset will cause the driver to unbind, causing the
usb_driver_lock_for_reset to stall.

      Arjan Mels authored 
      When shuting down the tcp_rx and tcp_tx threads first check if they are
not closed already (maybe because an error caused them to return).

      staging: hv: Fix GARP not sent after Quick Migration · c996edcf
      Haiyang Zhang authored 
      After Quick Migration, the network is not immediately operational in the
current context when receiving RNDIS_STATUS_MEDIA_CONNECT event. So, I added
another netif_notify_peers() into a scheduled work, otherwise GARP packet will
not be sent after quick migration, and cause network disconnection.

Thanks to Mike Surcouf <mike@surcouf.co.uk> for reporting the bug and
testing the patch.
