[GIT PULL] target fixes for v3.12-rc7

[Nicholas A. Bellinger]

Hello Linus!

Here are the outstanding target pending fixes for v3.12-rc7.

Please go ahead and pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git master

It includes a number of EXTENDED_COPY related fixes as a result of
Thomas and Doug's continuing testing and feedback.

Also included is an important vhost/scsi fix that addresses a long
standing issue where the 'write' parameter for get_user_pages_fast() was
incorrectly set for virtio-scsi WRITEs -> DMA_TO_DEVICE, and not for
virtio-scsi READs -> DMA_FROM_DEVICE.

This resulted in random userspace segfaults and other unpleasantness on
KVM host, and unfortunately has been an issue since the initial merge of
vhost/scsi in v3.6.  This patch is CC'ed to stable, along with two other
less critical items.

Thank you,

--nab
