Ard Biesheuvel 293614ce3e crypto: arm64/aes-blk - expose AES-CTR as synchronous cipher as well
In addition to wrapping the AES-CTR cipher into the async SIMD wrapper,
which exposes it as an async skcipher that defers processing to process
context, expose our AES-CTR implementation directly as a synchronous cipher
as well, but with a lower priority.

This makes the AES-CTR transform usable in places where synchronous
transforms are required, such as the MAC802.11 encryption code, which
executes in sotfirq context, where SIMD processing is allowed on arm64.
Users of the async transform will keep the existing behavior.

Ard Biesheuvel afaf712e99 crypto: arm/chacha20 - implement NEON version based on SSE3 code
This is a straight port to ARM/NEON of the x86 SSE3 implementation
of the ChaCha20 stream cipher. It uses the new skcipher walksize
attribute to process the input in strides of 4x the block size.

Arnd Bergmann 41e05324fd crypto: mediatek - fix format string for 64-bit builds
After I enabled COMPILE_TEST for non-ARM targets, I ran into these
warnings:

crypto/mediatek/mtk-aes.c: In function 'mtk_aes_info_map':
crypto/mediatek/mtk-aes.c:224:28: error: format '%d' expects argument of type 'int', but argument 3 has type 'long unsigned int' [-Werror=format=]

crypto/mediatek/mtk-sha.c:550:21: error: format '%u' expects argument of type 'unsigned int', but argument 4 has type 'size_t {aka long unsigned int}' [-Werror=format=]

The correct format for size_t is %zu, so use that in all three
cases.

Arnd Bergmann 7dee9f6187 crypto: mediatek - remove ARM dependencies
Building the mediatek driver on an older ARM architecture results in a
harmless warning:

warning: (ARCH_OMAP2PLUS_TYPICAL && CRYPTO_DEV_MEDIATEK) selects NEON which has unmet direct dependencies (VFPv3 && CPU_V7)

We could add an explicit dependency on CPU_V7, but it seems nicer to
open up the build to additional configurations. This replaces the ARM
optimized algorithm selection with the normal one that all other drivers
use, and that in turn lets us relax the dependency on ARM and drop
a number of the unrelated 'select' statements.

Obviously a real user would still select those other optimized drivers
as a fallback, but as there is no strict dependency, we can leave that
up to the user.

Andrew Lutomirski e93acd6f67 crypto: testmgr - Allocate only the required output size for hash tests
There are some hashes (e.g. sha224) that have some internal trickery
to make sure that only the correct number of output bytes are
generated.  If something goes wrong, they could potentially overrun
the output buffer.

Make the test more robust by allocating only enough space for the
correct output size so that memory debugging will catch the error if
the output is overrun.

Tested by intentionally breaking sha224 to output all 256
internally-generated bits while running on KASAN.

The function is used to check either the platform device ID name or the OF

device type was registered.

But the driver is for a DT-only platform and so there's no need for this
level of indirection since the devices can only be registered via OF.

Gideon Israel Dsouza d8c34b949d crypto: Replaced gcc specific attributes with macros from compiler.h
Continuing from this commit: 52f5684c8e
("kernel: use macros from compiler.h instead of __attribute__((...))")

I submitted 4 total patches. They are part of task I've taken up to
increase compiler portability in the kernel. I've cleaned up the
subsystems under /kernel /mm /block and /security, this patch targets
/crypto.

There is <linux/compiler.h> which provides macros for various gcc specific
constructs. Eg: __weak for __attribute__((weak)). I've cleaned all
instances of gcc specific attributes with the right macros for the crypto
subsystem.

I had to make one additional change into compiler-gcc.h for the case when
one wants to use this: __attribute__((aligned) and not specify an alignment
factor. From the gcc docs, this will result in the largest alignment for
that data type on the target machine so I've named the macro
__aligned_largest. Please advise if another name is more appropriate.

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:
     delete_node+0x1e4/0x200
     __radix_tree_delete_node+0xd/0x10
     shadow_lru_isolate+0xe6/0x220

     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.

Jérémy Lefaure 5563bb5743 usb: musb: blackfin: add bfin_fifo_offset in bfin_ops
The function bfin_fifo_offset is defined but not used:

drivers/usb/musb/blackfin.c:36:12: warning: ‘bfin_fifo_offset’ defined
but not used [-Wunused-function]
 static u32 bfin_fifo_offset(u8 epnum)
             ^~~~~~~~~~~~~~~~

Adding bfin_fifo_offset to bfin_ops fixes this warning and allows musb
core to call this function instead of default_fifo_offset.

Jérémy Lefaure c8bd2ac3b4 usb: musb: fix compilation warning on unused function
The function musb_run_resume_work is called only when CONFIG_PM is
enabled. So this function should not be defined when CONFIG_PM is
disabled. Otherwise the compiler issues a warning:

drivers/usb/musb/musb_core.c:2057:12: error: ‘musb_run_resume_work’ defined but
not used [-Werror=unused-function]
 static int musb_run_resume_work(struct musb *musb)

Tony Lindgren 8c300fe282 usb: musb: Fix trying to free already-free IRQ 4
When unloading omap2430, we can get the following splat:

WARNING: CPU: 1 PID: 295 at kernel/irq/manage.c:1478 __free_irq+0xa8/0x2c8
Trying to free already-free IRQ 4
...
[<c01a8b78>] (free_irq) from [<bf0aea84>]
(musbhs_dma_controller_destroy+0x28/0xb0 [musb_hdrc])
[<bf0aea84>] (musbhs_dma_controller_destroy [musb_hdrc]) from

[<bf09f88c>] (musb_remove [musb_hdrc]) from [<c056a384>]
(platform_drv_remove+0x24/0x3c)
...

This is because the irq number in use is 260 nowadays, and the dma
controller is using u8 instead of int.
