There are multiple ingredients for this:
1) PAGE_NONE is defined to _CACHE_CACHABLE_NONCOHERENT, which is CCA 3
on all platforms except SB1 where it's CCA 5.
2) _page_cachable_default must have bits set which are not set
_CACHE_CACHABLE_NONCOHERENT.
3) Either the defective version of pte_modify for XPA or the standard
version must be in used. However pte_modify for the 36 bit address
space support is no affected.
In that case additional bits in the final CCA mode may generate an invalid
value for the CCA field. On the R10000 system where this was tracked
down for example a CCA 7 has been observed, which is Uncached Accelerated.
Fixed by:
1) Using the proper CCA mode for PAGE_NONE just like for all the other
PAGE_* pte/pmd bits.
2) Fix the two affected variants of pte_modify.
Further code inspection also shows the same issue to exist in pmd_modify
which would affect huge page systems.
Issue in pte_modify tracked down by Alastair Bridgewater, PAGE_NONE
and pmd_modify issue found by me.
The history of this goes back beyond Linus' git history. Chris Dearman's
commit 351336929c ("[MIPS] Allow setting of
the cache attribute at run time.") missed the opportunity to fix this
but it was originally introduced in lmo commit
d523832cf12007b3242e50bb77d0c9e63e0b6518 ("Missing from last commit.")
and 32cc38229ac7538f2346918a09e75413e8861f87 ("New configuration option
CONFIG_MIPS_UNCACHED.")

Merge tag 'iommu-fixes-v4.7-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU fixes from Joerg Roedel:
"Three fixes:
- Fix use of smp_processor_id() in preemptible code in the IOVA
allocation code. This got introduced with the scalability
improvements in this release cycle.
- A VT-d fix for out-of-bounds access of the iommu->domains array.
The bug showed during suspend/resume.
- AMD IOMMU fix to print the correct device id in the ACPI parsing
code"
* tag 'iommu-fixes-v4.7-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu:
iommu/amd: Initialize devid variable before using it
iommu/vt-d: Fix overflow of iommu->domains array
iommu/iova: Disable preemption around use of this_cpu_ptr()
(Another one for the f_path debacle.)
ltp fcntl33 testcase caused an Oops in selinux_file_send_sigiotask.
The reason is that generic_add_lease() used filp->f_path.dentry->inode
while all the others use file_inode(). This makes a difference for files
opened on overlayfs since the former will point to the overlay inode the
latter to the underlying inode.
So generic_add_lease() added the lease to the overlay inode and
generic_delete_lease() removed it from the underlying inode. When the file
was released the lease remained on the overlay inode's lock list, resulting
in use after free.

- m_start() in fs/namespace.c expects that ns->event is incremented each
time a mount added or removed from ns->list.
- umount_tree() removes items from the list but does not increment event
counter, expecting that it's done before the function is called.
- There are some codepaths that call umount_tree() without updating
"event" counter. e.g. from __detach_mounts().
- When this happens m_start may reuse a cached mount structure that no
longer belongs to ns->list (i.e. use after free which usually leads
to infinite loop).
This change fixes the above problem by incrementing global event counter
before invoking umount_tree().

v9fs may be used as lower layer of overlayfs and accessing f_path.dentry
can lead to a crash. In this case it's a NULL pointer dereference in
p9_fid_create().
Fix by replacing direct access of file->f_path.dentry with the
file_dentry() accessor, which will always return a native object.

Commit d6a9996e84 ("powerpc/mm: vmalloc abstraction in preparation for
radix") turned kernel memory and IO addresses from #defined constants to
variables initialised at runtime.
On PA6T (pasemi) systems the setup_arch() machine call initialises the
onboard PCI-e root-ports, and uses pci_io_base to do this, which is now
before its value has been set, resulting in a panic early in boot before
console IO is initialised.
Move the pci_io_base initialisation to the same place as vmalloc ranges
are set (hash__early_init_mmu()/radix__early_init_mmu()) - this is the
earliest possible place we can initialise it.

Pull audit fixes from Paul Moore:
"Two small patches to fix audit problems in 4.7-rcX: the first fixes a
potential kref leak, the second removes some header file noise.
The first is an important bug fix that really should go in before 4.7
is released, the second is not critical, but falls into the very-nice-
to-have category so I'm including in the pull request.
Both patches are straightforward, self-contained, and pass our
testsuite without problem"

Consumers need to be able to specify whether they are requesting an
'exclusive' or 'shared' reset line no matter which API (of_*, devm_*,
etc) they are using. This change allows users of the optional_* API
in particular to specify that their request is for a 'shared' line.

Phasing out generic reset line requests enables us to make some better
decisions on when and how to (de)assert said lines. If an 'exclusive'
line is requested, we know a device *requires* a reset and that it's
preferable to act upon a request right away. However, if a 'shared'
reset line is requested, we can reasonably assume sure that placing a
device into reset isn't a hard requirement, but probably a measure to
save power and is thus able to cope with not being asserted if another
device is still in use.
In order allow gentle adoption and not to forcing all consumers to
move to the API immediately, causing administration headache between
subsystems, this patch adds some temporary stand-in shim-calls. This
will ease the burden at merge time and allow subsystems to migrate over
to the new API in a more realistic time-frame.

We're about to split the current API into two, where consumers will
be forced to be explicit when requesting reset lines. The choice
will be to either the call the *_exclusive or *_shared variant
depending on whether they can actually tolorate not being asserted
when that request is made.
The new API will look like this once reorded and complete:
reset_control_get_exclusive()
reset_control_get_shared()
reset_control_get_optional_exclusive()
reset_control_get_optional_shared()
of_reset_control_get_exclusive()
of_reset_control_get_shared()
of_reset_control_get_exclusive_by_index()
of_reset_control_get_shared_by_index()
devm_reset_control_get_exclusive()
devm_reset_control_get_shared()
devm_reset_control_get_optional_exclusive()
devm_reset_control_get_optional_shared()
devm_reset_control_get_exclusive_by_index()

Per JEDEC Annex L Release 3 the SPD data is:
Bits 9~5 00 000 = Function Undefined
00 001 = Byte addressable energy backed
00 010 = Block addressed
00 011 = Byte addressable, no energy backed
All other codes reserved
Bits 4~0 0 0000 = Proprietary interface
0 0001 = Standard interface 1
All other codes reserved; see Definitions of Functions
...and per the ACPI 6.1 spec:
byte0: Bits 4~0 (0 or 1)
byte1: Bits 9~5 (1, 2, or 3)
...so a format interface code displayed as 0x301 should be stored in the
nfit as (0x1, 0x3), little-endian.
