Since commit 1196c2fb a domain is only destroyed in the
notifier path if it is hot-unplugged. This caused a
domain leakage in iommu_attach_device when a driver was
unbound from the device and bound to VFIO. In this case the
device is attached to a new domain and unlinked from the old
domain. At this point nothing points to the old domain
anymore and its memory is leaked.
Fix this by explicitly freeing the old domain in
iommu_attach_domain.

Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Before commit 0e60b079 (kvm: change memslot sorting rule from size
to GFN, 2014-12-01), the memslots' sorting key was npages, meaning
that a valid memslot couldn't have its sorting key equal to zero.
On the other hand, a valid memslot can have base_gfn == 0, and invalid
memslots are identified by base_gfn == npages == 0.

Because of this, commit 0e60b079 broke the invariant that invalid
memslots are at the end of the mslots array.  When a memslot with
base_gfn == 0 was created, any invalid memslot before it were left
in place.

This can be fixed by changing the insertion to use a ">=" comparison
instead of "<=", but some care is needed to avoid breaking the case
of deleting a memslot; see the comment in update_memslots.

This broke userspace by not returning the same information that was sent and
expected.

On arm64 the TTBR0_EL1 register is set to either the reserved TTBR0
page tables on boot or to the active_mm mappings belonging to user space
processes, it must never be set to swapper_pg_dir page tables mappings.

When a CPU is booted its active_mm is set to init_mm even though its
TTBR0_EL1 points at the reserved TTBR0 page mappings. This implies
that when __cpu_suspend is triggered the active_mm can point at
init_mm even if the current TTBR0_EL1 register contains the reserved
TTBR0_EL1 mappings.

Therefore, the mm save and restore executed in __cpu_suspend might
turn out to be erroneous in that, if the current->active_mm corresponds
to init_mm, on resume from low power it ends up restoring in the
TTBR0_EL1 the init_mm mappings that are global and can cause speculation
of TLB entries which end up being propagated to user space.

This patch fixes the issue by checking the active_mm pointer before
restoring the TTBR0 mappings. If the current active_mm == &init_mm,
the code sets the TTBR0_EL1 to the reserved TTBR0 mapping instead of
switching back to the active_mm, which is the expected behaviour
corresponding to the TTBR0_EL1 settings when __cpu_suspend was entered.

drm/tegra: Fixes for v3.19-rc1

This is a set of fixes for two regressions and one bug in the IOMMU
mapping code. It turns out that all of these issues turn up primarily
on Tegra30 hardware. The IOMMU mapping bug only manifests on buffers
that aren't multiples of the page size. I happened to be testing HDMI
with 1080p while writing the code and framebuffers for that happen to
fit exactly within 2025 pages of 4 KiB each.

One of the regressions is caused by the IOMMU code allocating pages from
shmem which can have associated cache lines. If the pages aren't flushed
then these cache lines may be flushed later on and cause framebuffer
corruption. I'm not sure why I didn't see this before. Perhaps the board
that I was using had enough RAM so that the pages shmem would hand out
had a better chance of being unused. Or maybe I didn't look too closely.
The fix for this is to fake up an SG table so that it can be passed to
the DMA API. Ideally this would use drm_clflush_*(), but implementing
that for ARM causes DRM to fail to build as a module since some of the
low-level cache maintenance functions aren't exported. Hopefully we can
get a suitable API exported on ARM for the next release.

The second regression is caused by a mismatch between the hardware pipe
number and the CRTC's DRM index. These were used inconsistently, which
could cause one code location to call drm_vblank_get() with a different
pipe than the corresponding drm_vblank_put(), thereby causing the
reference count to become unbalanced. Alexandre also reported a possible
race condition related to this, which this series also fixes.

There is a problem with the audit system when multiple audit records
are created for the same path, each with a different path name type.
The root cause of the problem is in __audit_inode() when an exact
match (both the path name and path name type) is not found for a
path name record; the existing code creates a new path name record,
but it never sets the path name in this record, leaving it NULL.
This patch corrects this problem by assigning the path name to these
newly created records.

There are many ways to reproduce this problem, but one of the
easiest is the following (assuming auditd is running):

  # mkdir /root/tmp/test
  # touch /root/tmp/test/567
  # auditctl -a always,exit -F dir=/root/tmp/test
  # touch /root/tmp/test/567

Afterwards, or while the commands above are running, check the audit
log and pay special attention to the PATH records.  A faulty kernel
will display something like the following for the file creation:

  type=SYSCALL msg=audit(1416957442.025:93): arch=c000003e syscall=2
    success=yes exit=3 ... comm="touch" exe="/usr/bin/touch"
  type=CWD msg=audit(1416957442.025:93):  cwd="/root/tmp"
  type=PATH msg=audit(1416957442.025:93): item=0 name="test/"
    inode=401409 ... nametype=PARENT
  type=PATH msg=audit(1416957442.025:93): item=1 name=(null)
    inode=393804 ... nametype=NORMAL
  type=PATH msg=audit(1416957442.025:93): item=2 name=(null)
    inode=393804 ... nametype=NORMAL

While a patched kernel will show the following:

  type=SYSCALL msg=audit(1416955786.566:89): arch=c000003e syscall=2
    success=yes exit=3 ... comm="touch" exe="/usr/bin/touch"

Pull ACCESS_ONCE cleanup preparation from Christian Borntraeger:
 "kernel: Provide READ_ONCE and ASSIGN_ONCE

  As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com
  ACCESS_ONCE might fail with specific compilers for non-scalar
  accesses.

  Here is a set of patches to tackle that problem.

  The first patch introduce READ_ONCE and ASSIGN_ONCE.  If the data
  structure is larger than the machine word size memcpy is used and a
  warning is emitted.  The next patches fix up several in-tree users of
  ACCESS_ONCE on non-scalar types.

  This does not yet contain a patch that forces ACCESS_ONCE to work only
  on scalar types.  This is targetted for the next merge window as Linux
  next already contains new offenders regarding ACCESS_ONCE vs.
  non-scalar types"

Pull clk framework updates from Mike Turquette:
 "This is much later than usual due to several last minute bugs that had
  to be addressed.  As usual the majority of changes are new drivers and
  modifications to existing drivers.  The core recieved many fixes along
  with the groundwork for several large changes coming in the future
  which will better parition clock providers from clock consumers"
