Andrew Bresticker d771fdf941 pstore/ram: Use memcpy_fromio() to save old buffer
The ramoops buffer may be mapped as either I/O memory or uncached
memory.  On ARM64, this results in a device-type (strongly-ordered)
mapping.  Since unnaligned accesses to device-type memory will
generate an alignment fault (regardless of whether or not strict
alignment checking is enabled), it is not safe to use memcpy().
memcpy_fromio() is guaranteed to only use aligned accesses, so use
that instead.

Furquan Shaikh 7e75678d23 pstore/ram: Use memcpy_toio instead of memcpy
persistent_ram_update uses vmap / iomap based on whether the buffer is in
memory region or reserved region. However, both map it as non-cacheable
memory. For armv8 specifically, non-cacheable mapping requests use a
memory type that has to be accessed aligned to the request size. memcpy()
doesn't guarantee that.

Mark Salyzyn 5bf6d1b927 pstore/pmsg: drop bounce buffer
Removing a bounce buffer copy operation in the pmsg driver path is
always better. We also gain in overall performance by not requesting
a vmalloc on every write as this can cause precious RT tasks, such
as user facing media operation, to stall while memory is being
reclaimed. Added a write_buf_user to the pstore functions, a backup
platform write_buf_user that uses the small buffer that is part of
the instance, and implemented a ramoops write_buf_user that only
supports PSTORE_TYPE_PMSG.

Namhyung Kim 79d955af71 pstore/ram: Set pstore flags dynamically
The ramoops can be configured to enable each pstore type by setting
their size.  In that case, it'd be better not to register disabled types
in the first place.

Namhyung Kim c950fd6f20 pstore: Split pstore fragile flags
This patch adds new PSTORE_FLAGS for each pstore type so that they can
be enabled separately.  This is a preparation for ongoing virtio-pstore
work to support those types flexibly.

The PSTORE_FLAGS_FRAGILE is changed to PSTORE_FLAGS_DMESG to preserve the
original behavior.

Sebastian Andrzej Siewior d5a9bf0b38 pstore/core: drop cmpxchg based updates
I have here a FPGA behind PCIe which exports SRAM which I use for
pstore. Now it seems that the FPGA no longer supports cmpxchg based
updates and writes back 0xff…ff and returns the same.  This leads to
crash during crash rendering pstore useless.
Since I doubt that there is much benefit from using cmpxchg() here, I am
dropping this atomic access and use the spinlock based version.

Sebastian Andrzej Siewior 4407de74df pstore/ramoops: fixup driver removal
A basic rmmod ramoops segfaults. Let's see why.

Since commit 34f0ec82e0 ("pstore: Correct the max_dump_cnt clearing of
ramoops") sets ->max_dump_cnt to zero before looping over ->przs but we
didn't use it before that either.

And since commit ee1d267423 ("pstore: add pstore unregister") we free
that memory on rmmod.

But even then, we looped until a NULL pointer or ERR. I don't see where
it is ensured that the last member is NULL. Let's try this instead:
simply error recovery and free. Clean up in error case where resources
were allocated. And then, in the free path, rely on ->max_dump_cnt in
the free path.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull rdma fixes from Doug Ledford:
 "This is the second pull request for the rdma subsystem.  Most of the
  patches are small and obvious.  I took two patches in that are larger
  than I wanted this late in the cycle.

  The first is the hfi1 patch that implements a work queue to test the
  QSFP read state.  I originally rejected the first patch for this
  (which would have place up to 20 seconds worth of udelays in their
  probe routine).  They then rewrote it the way I wanted (use delayed
  work tasks to wait asynchronously up to 20 seconds for the QSFP to
  come alive), so I can't really complain about the size of getting what
  I asked for :-/.

  The second is large because it switches the rcu locking in the debugfs
  code.  Since a locking change like this is done all at once, the size
  it what it is.  It resolves a litany of debug messages from the
  kernel, so I pulled it in for -rc.

  The rest are all typical -rc worthy patches I think.

  There will still be a third -rc pull request from the rdma subsystem

Kees Cook 3c17648c28 lkdtm: adjust usercopy tests to bypass const checks
The hardened usercopy is now consistently avoiding checks against const
sizes, since we really only want to perform runtime bounds checking
on lengths that weren't known at build time. To test the hardened usercopy
code, we must force the length arguments to be seen as non-const.

Kees Cook e6971009a9 x86/uaccess: force copy_*_user() to be inlined
As already done with __copy_*_user(), mark copy_*_user() as __always_inline.
Without this, the checks for things like __builtin_const_p() won't work
consistently in either hardened usercopy nor the recent adjustments for
detecting usercopy overflows at compile time.

The change in kernel text size is detectable, but very small:

Linus Torvalds 6296c41259 SCSI fixes on 20160906
This is really three fixes, but the SES one comes in a bundle of three
 (making the replacement API available properly, using it and removing
 the non-working one).  The SES problem causes an oops on hpsa devices
 because they attach virtual disks to the host which aren't SAS
 attached (the replacement API ignores them).  The other two fixes are
 fairly minor: the sense key one means we actually resolve a newly
 added sense key and the RDAC device blacklisting is needed to prevent
 us annoying the universal XPORT lun of various RDAC arrays.

Linus Torvalds ec9a03d47e regmap: Fixes for v4.8
Several fixes here, the main one being the change from Lars-Peter which
 I'd been letting soak in -next since the merge window in case it
 uncovered further issues as it's a minimal fix rather than a change
 addressing the root cause of the problems (which would've been too
 invasive for -rc):
 
  - The biggest change is a fix from Lars-Peter to ensure that we don't
    create overlapping rbtree nodes which in turn avoids returning
    corrupt cache values to users, fixing some issues that were exposed
    by some recent optimisations with certain access patterns but had
    been present for a long time.
  - A fix from Elaine Zhang to stop us updating the cache if we get an
    I/O error when writing to the hardware.
  - A fix fromm Maarten ter Huurne to avoid uninitialized defaults in
    cases where we have non-readable registers but are initializing the
    cache by reading from the device.

Dirk Behme 87260d3f7a thermal: rcar_thermal: Fix priv->zone error handling
In case thermal_zone_xxx_register() returns an error, priv->zone
isn't NULL any more, but contains the error code.

This is passed to thermal_zone_device_unregister(), then. This checks
for priv->zone being NULL, but the error code is != NULL. So it works
with the error code as a pointer. Crashing immediately.

To fix this, reset priv->zone to NULL before entering
rcar_gen3_thermal_remove().

Linus Torvalds 3e423945ea devpts: return NULL pts 'priv' entry for non-devpts nodes
In commit 8ead9dd547 ("devpts: more pty driver interface cleanups") I
made devpts_get_priv() just return the dentry->fs_data directly.  And
because I thought it wouldn't happen, I added a warning if you ever saw
a pts node that wasn't on devpts.

And no, that warning never triggered under any actual real use, but you
can trigger it by creating nonsensical pts nodes by hand.

So just revert the warning, and make devpts_get_priv() return NULL for
that case like it used to.

Sien Wu d0716dde37 spi: Prevent unexpected SPI time out due to arithmetic overflow
When reading SPI flash as MTD device, the transfer length is
directly passed to the spi driver. If the requested data size
exceeds 512KB, it will cause the time out calculation to
overflow since transfer length is 32-bit unsigned integer.
This issue is resolved by using 64-bit unsigned integer
to perform the arithmetic.
