Changbin Du cdcc43479c drm/i915/gvt: move mmio init/clean function to mmio.c
Move the mmio space inititation function setup_vgpu_mmio()
and cleanup function clean_vgpu_mmio() in vgpu.c to dedicated
source file mmio.c, and rename them as intel_vgpu_init_mmio()
and intel_vgpu_clean_mmio() respectively.

Changbin Du c64ff6c774 drm/i915/gvt: introduce intel_vgpu_reset_cfg_space to reset configuration space
This patch introduces a new function intel_vgpu_reset_cfg_space()
to reset vGPU configuration space. This function will unmap gttmmio
and aperture if they are mapped before. Then entire cfg space will
be restored to default values.

Currently we only do such reset when vGPU is not owned by any VM
so we simply restore entire cfg space to default value, not following
the PCIe FLR spec that some fields should remain unchanged.

Changbin Du b611581b37 drm/i915/gvt: introuduce intel_vgpu_reset_gtt() to reset gtt
This patch introduces a new function intel_vgpu_reset_gtt() to reset
the all GTT related status, including GGTT, PPGTT, scratch page. This
function can free all shadowed PPGTT, clear all GGTT entry, and clear
scratch page to all zero. After this, we can ensure no gtt related
information can be leakaged from one VM to anothor one when assign
vgpu instance across different VMs (not simultaneously).

This patch introudces a new function intel_vgpu_reset_resource() to

Jike Song 03551e971f drm/i915/gvt: cleanup opregion memory allocation code
According to the spec, ACPI OpRegion must be placed at a physical address
below 4G. That is, for a vGPU it must be associated with a GPA below 4G,
but on host side, it doesn't matter where the backing pages actually are.
So when allocating pages from host, the GFP_DMA32 flag is unnecessary.

Also the allocation is from a sleepable context, so GFP_ATOMIC is also
unnecessary.

This patch also removes INTEL_GVT_OPREGION_PORDER and use get_order()
instead.

Nicolas Iooss 3e70c5d6ea drm/i915/gvt: verify functions types in new_mmio_info()
The current prototype of new_mmio_info() uses void* for parameters read
and write, which are functions with precise calling conventions
(argument types and return type). Write down these conventions in
new_mmio_info() definition.

This has been reported by the following warnings when clang is used to
build the kernel:

    drivers/gpu/drm/i915/gvt/handlers.c:124:21: error: pointer type
    mismatch ('void *' and 'int (*)(struct intel_vgpu *, unsigned int,
    void *, unsigned int)') [-Werror,-Wpointer-type-mismatch]
            info->read = read ? read : intel_vgpu_default_mmio_read;
                              ^ ~~~~   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    drivers/gpu/drm/i915/gvt/handlers.c:125:23: error: pointer type
    mismatch ('void *' and 'int (*)(struct intel_vgpu *, unsigned int,

                                ^ ~~~~~   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This allows the compiler to detect that sbi_ctl_mmio_write() returns a
"bool" value instead of an expected "int" one. Fix this.

Johannes Weiner ea07b862ac mm: workingset: fix use-after-free in shadow node shrinker
Several people report seeing warnings about inconsistent radix tree
nodes followed by crashes in the workingset code, which all looked like
use-after-free access from the shadow node shrinker.

Dave Jones managed to reproduce the issue with a debug patch applied,
which confirmed that the radix tree shrinking indeed frees shadow nodes
while they are still linked to the shadow LRU:

  WARNING: CPU: 2 PID: 53 at lib/radix-tree.c:643 delete_node+0x1e4/0x200
  CPU: 2 PID: 53 Comm: kswapd0 Not tainted 4.10.0-rc2-think+ #3
  Call Trace:

     shrink_node+0x22c/0x330
     kswapd+0x392/0x8f0

This is the WARN_ON_ONCE(!list_empty(&node->private_list)) placed in the
inlined radix_tree_shrink().

The problem is with 14b468791f ("mm: workingset: move shadow entry
tracking to radix tree exceptional tracking"), which passes an update
callback into the radix tree to link and unlink shadow leaf nodes when
tree entries change, but forgot to pass the callback when reclaiming a
shadow node.

While the reclaimed shadow node itself is unlinked by the shrinker, its
deletion from the tree can cause the left-most leaf node in the tree to
be shrunk.  If that happens to be a shadow node as well, we don't unlink
it from the LRU as we should.

Consider this tree, where the s are shadow entries:

       root->rnode
            |
       [0       n]
        |       |
     [s    ] [sssss]

Now the shadow node shrinker reclaims the rightmost leaf node through
the shadow node LRU:

       root->rnode
            |
       [0        ]
        |
    [s     ]

Because the parent of the deleted node is the first level below the
root and has only one child in the left-most slot, the intermediate
level is shrunk and the node containing the single shadow is put in
its place:

       root->rnode
            |
       [s        ]

The shrinker again sees a single left-most slot in a first level node
and thus decides to store the shadow in root->rnode directly and free
the node - which is a leaf node on the shadow node LRU.

  root->rnode
       |
       s

Without the update callback, the freed node remains on the shadow LRU,
where it causes later shrinker runs to crash.

Pass the node updater callback into __radix_tree_delete_node() in case
the deletion causes the left-most branch in the tree to collapse too.

Also add warnings when linked nodes are freed right away, rather than
wait for the use-after-free when the list is scanned much later.

Hugh Dickins b0b9b3df27 mm: stop leaking PageTables
4.10-rc loadtest (even on x86, and even without THPCache) fails with
"fork: Cannot allocate memory" or some such; and /proc/meminfo shows
PageTables growing.

Commit 953c66c2b2 ("mm: THP page cache support for ppc64") that got
merged in rc1 removed the freeing of an unused preallocated pagetable
after do_fault_around() has called map_pages().

This is usually a good optimization, so that the followup doesn't have
to reallocate one; but it's not sufficient to shift the freeing into
alloc_set_pte(), since there are failure cases (most commonly
VM_FAULT_RETRY) which never reach finish_fault().

Check and free it at the outer level in do_fault(), then we don't need
to worry in alloc_set_pte(), and can restore that to how it was (I
cannot find any reason to pte_free() under lock as it was doing).

And fix a separate pagetable leak, or crash, introduced by the same
change, that could only show up on some ppc64: why does do_set_pmd()'s
failure case attempt to withdraw a pagetable when it never deposited
one, at the same time overwriting (so leaking) the vmf->prealloc_pte?
Residue of an earlier implementation, perhaps? Delete it.

Merge tag 'pm-4.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management fixes from Rafael Wysocki:
 "These fix a few issues in the intel_pstate driver, a documetation
  issue, a false-positive compiler warning in the generic power domains
  framework and two problems in the devfreq subsystem. They also update
  the MAINTAINERS entry for devfreq and add a new "compatible" string to
  the generic cpufreq-dt driver.

  Specifics:

   - Fix a few intel_pstate driver issues: add missing locking it two
     places, avoid exposing a useless debugfs interface and keep the
     attribute values in sysfs in sync (Rafael Wysocki).

   - Drop confusing kernel-doc references related to power management
     and ACPI from the driver API manual (Rafael Wysocki).

   - Make a false-positive compiler warning in the generic power domains
     framework go away (Augusto Mecking Caringi).

   - Fix two initialization issues in the devfreq subsystem and update
     the MAINTAINERS entry for it (Chanwoo Choi).

   - Add a new "compatible" string for APM X-Gene 2 to the generic DT
     cpufreq driver (Hoan Tran)"

Konrad Rzeszutek Wilk 7453c549f5 swiotlb: Export swiotlb_max_segment to users
So they can figure out what is the optimal number of pages
that can be contingously stitched together without fear of
bounce buffer.

We also expose an mechanism for sub-users of SWIOTLB API, such
as Xen-SWIOTLB to set the max segment value. And lastly
if swiotlb=force is set (which mandates we bounce buffer everything)
we set max_segment so at least we can bounce buffer one 4K page
instead of a giant 512KB one for which we may not have space.

The gpiod_get* function family does not want the -gpio suffix.
Use devm_gpiod_get_index_optional instead of devm_gpiod_get_optional.
The descriptor based APIs handle active high/low automatically.
The vbus-gpios are output, request enable while getting the gpio.
Don't try to get any vbus-gpios for ports outside num-ports.

Linus Torvalds b400792732 This is a rather large set of bugfixes, as we just returned from the
Christmas break. Most of these are relatively unimportant fixes for
 regressions introduced during the merge window, and about half of
 the changes are for mach-omap2.
 
 A couple of patches are just cleanups and dead code removal that I would
 not normally have considered for merging after -rc2, but I decided to
 take them along with the fixes this time.
 
 Notable fixes include:
 
 - removing the skeleton.dtsi include broke a number of machines, and we
   have to put empty /chosen nodes back to be able to pass kernel command
   lines as before
 
 - enabling Samsung platforms no longer hardwires CONFIG_HZ to 200,
   as it had been for no good reason for a long time.
