pULL SCSI fixes from James Bottomley:
"This consists of four real fixes and three MAINTAINER updates.Three of the fixes are obvious (the DIX and atomic allocation are bug
on and warn on fixes and the other is just trivial) and the ipr one is
a bit more involved but is required because without it, the card
double completes aborted commands and causes a kernel oops"* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:

Pull hwmon update from Jean Delvare:
"This contains a single thing: a new driver for the temperature sensor
embedded in the Intel 5500/5520/X58 chipsets.Sorry for the late request, it's been so long since I last sent a pull
request and I've been so busy with other tasks meanwhile that I simply
forgot about these patches. But given that this is a new driver, it
can't introduce any regression so I thought it could still be OK.This has been in linux-next for months now"

SYSENTER emulation is broken in several ways:
1. It misses the case of 16-bit code segments completely (CVE-2015-0239).
2. MSR_IA32_SYSENTER_CS is checked in 64-bit mode incorrectly (bits 0 and 1 can
still be set without causing #GP).
3. MSR_IA32_SYSENTER_EIP and MSR_IA32_SYSENTER_ESP are not masked in
legacy-mode.
4. There is some unneeded code.Fix it.

The VIDIOC_QUERYCAP function should set device_caps, but this was missing.
In addition, it set the version field as well, but that should be done by
the core, not by the driver.If a driver doesn't set device_caps the v4l2 core will issue a WARN_ON, so
it's important that this is set correctly.Signed-off-by: Hans Verkuil

The locking scheme inside the vb2 thread is unsafe when stopping the
thread. In particular kthread_stop was called *after* internal data
structures were cleaned up instead of doing that before. In addition,
internal vb2 functions were called after threadio->stop was set to
true and vb2_internal_streamoff was called. This is also not allowed.All this led to a variety of race conditions and kernel warnings and/or
oopses.Fixed by moving the kthread_stop call up before the cleanup takes
place, and by checking threadio->stop before calling internal vb2
queuing operations.Signed-off-by: Hans Verkuil
