Pull libnvdimm fix from Dan Williams:
"We expanded the device-dax fs type in 4.12 to be a generic provider of
a struct dax_device with an embedded inode. However, Sasha found some
basic negative testing was not run to verify that this fs cleanly
handles being mounted directly.

Note that the fresh rebase was done to remove an unnecessary Cc:
<stable> tag, but this commit otherwise had a build success
notification from the 0day robot."

device-dax: fix 'dax' device filesystem inode destruction crash

If logout response is not received and ->ep_disconnect() is called then
close tcp conn by RST instead of FIN to cleanup conn resources
immediately.

Also move ->csk_push_tx_frames() above 'done:' to avoid calling
->csk_push_tx_frames() in error cases.

Pull hexagon fix from Guenter Roeck:
"This fixes a build error seen when building hexagon images.

Richard sent me an Ack, but didn't reply when asked if he wants me to
send the patch to you directly, so I figured I'd just do it"

hexagon: Use raw_copy_to_user

The inode destruction path for the 'dax' device filesystem incorrectly
assumes that the inode was initialized through 'alloc_dax()'. However,
if someone attempts to directly mount the dax filesystem with 'mount -t
dax dax mnt' that will bypass 'alloc_dax()' and the following failure
signatures may occur as a result:

Currently VBUS is turned off while a usb device is detached, and turned
on again by the polling routine. This short period VBUS loss prevents
usb modem to switch mode.

VBUS should be constantly on for host-only mode, so this changes the
driver to not turn off VBUS for host-only mode.
