  mm: compaction: correct the nr_strict va isolated check for CMA
  firmware/memmap: avoid type conflicts with the generic memmap_init()
  pidns: remove recursion from free_pid_ns()

Ming Lei fe73fbe1c5 lib/dma-debug.c: fix __hash_bucket_find()
If there is only one match, the unique matched entry should be returned.

Without the fix, the upcoming dma debug interfaces ("dma-debug: new
interfaces to debug dma mapping errors") can't work reliably because
only device and dma_addr are passed to dma_mapping_error().

Mel Gorman 0db63d7e25 mm: compaction: correct the nr_strict va isolated check for CMA
Thierry reported that the "iron out" patch for isolate_freepages_block()
had problems due to the strict check being too strict with "mm:
compaction: Iron out isolate_freepages_block() and
isolate_freepages_range() -fix1".  It's possible that more pages than
necessary are isolated but the check still fails and I missed that this
fix was not picked up before RC1.  This same problem has been identified
in 3.7-RC1 by Tony Prisk and should be addressed by the following patch.

Cyrill Gorcunov bbc2e3ef87 pidns: remove recursion from free_pid_ns()
free_pid_ns() operates in a recursive fashion:

free_pid_ns(parent)
  put_pid_ns(parent)
    kref_put(&ns->kref, free_pid_ns);
      free_pid_ns

thus if there was a huge nesting of namespaces the userspace may trigger
avalanche calling of free_pid_ns leading to kernel stack exhausting and a
panic eventually.

This patch turns the recursion into an iterative loop.

Based on a patch by Andrew Vagin.

Kees Cook 2702b1526c kernel/sys.c: fix stack memory content leak via UNAME26
Calling uname() with the UNAME26 personality set allows a leak of kernel
stack contents.  This fixes it by defensively calculating the length of
copy_to_user() call, making the len argument unsigned, and initializing
the stack buffer to zero (now technically unneeded, but hey, overkill).

Linus Torvalds deb521c44f remap_file_pages: correctly handle the case of a NULL vm_ops pointer
In commit 0b173bc4da ("mm: kill vma flag VM_CAN_NONLINEAR") we
replaced the VM_CAN_NONLINEAR test with checking whether the mapping has
a '->remap_pages()' vm operation, but there is no guarantee that there
it even has a vm_ops pointer at all.

Add the appropriate test for NULL vm_ops.

Linus Torvalds b05e585d49 kbuild: Fix module signature generation
Rusty had clearly not actually tested his module signing changes that I
(trustingly) applied as commit e2a666d52b ("kbuild: sign the modules
at install time"). That commit had multiple bugs:

 - using "${#VARIABLE}" to get the number of characters in a shell
   variable may look clever, but it's locale-dependent: it returns the
   number of *characters*, not bytes. And we do need bytes.

   So don't use "${#..}" expansion, do the stupid "wc -c" thing instead
   (where "c" stands for "bytes", not "characters", despite the letter.

 - Rusty had confused "siglen" and "signerlen", and his conversion
   didn't set "signerlen" at all, and incorrectly set "siglen" to the
   size of the signer, not the size of the signature.

End result: the modified sign-file script did create something that
superficially *looked* like a signature, but didn't actually work at
all, and would fail the signature check. Oops.

Tssk, tssk, Rusty.

But Rusty was definitely right that this whole thing should be rewritten
in perl by somebody who has the perl-fu to do so.  That is not me,
though - I'm just doing an emergency fix for the shell script.

Linus Torvalds 16757372ff xen: Fix annoying compile-time warning
Commit cb6b6df111 ("xen/pv-on-hvm kexec: add quirk for Xen 3.4 and
shutdown watches.") added the xen_strict_xenbus_quirk() function with an
old K&R-style declaration without proper typing, causing gcc to rightly
complain:

  drivers/xen/xenbus/xenbus_xs.c:628:13: warning: function declaration isn’t a prototype [-Wstrict-prototypes]

because we really don't live in caves using stone-age tools any more,
and the kernel has always used properly typed ANSI C function
declarations.

So if a function doesn't take arguments, we tell the compiler so
explicitly by adding the proper "void" in the prototype.

I'm sure there are tons of other examples of this kind of stuff in the
tree, but this is the one that hits my workstation config, so..

 There are the usual UABI header file movements, and we finally are now

 Other than that, nothing major, just a number of bugfixes and new device

 how they were handling their internal data, leaking memory, hence all of
 those fixups.

H. Peter Anvin 4533d86270 Merge commit '5bc66170dc486556a1e36fd384463536573f4b82' into x86/urgent
From Borislav Petkov <bp@amd64.org>:

Below is a RAS fix which reverts the addition of a sysfs attribute
which we agreed is not needed, post-factum. And this should go in now
because that sysfs attribute is going to end up in 3.7 otherwise and
thus exposed to userspace; removing it then would be a lot harder.

This is done as a merge rather than a simple patch/cherry-pick since
the baseline for this patch was not in the previous x86/urgent.

450cc20103 ("x86/mce: Provide boot argument to honour bios-set CMCI
threshold") added the bios_cmci_threshold sysfs attribute which was
supposed to communicate to userspace tools that BIOS CMCI threshold has
been honoured.

However, this info is not of any importance to userspace - it should
rather get the actual error count it has been thresholded already from
MCi_STATUS[38:52].

So drop this before it becomes a used interface (good thing we caught
this early in 3.7-rc1, right after the merge window closed).

Linus Torvalds c9623de4fc Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media fixes from Mauro Carvalho Chehab:
 "Media fixes for:
   - one Kconfig fix patch;
   - one patch fixing DocBook breakage due to the drivers/media UAPI
     changes;
   - the remaining UAPI media changes (DVB API).

  I'm aware that is is a little late for the UAPI renames for the DVB
  API, but IMHO, it is better to merge it for 3.7, due to two reasons:

   1) There is a major rename at 3.7 (not only uapi changes, but also
      the entire media drivers were reorganized on 3.7, in order to
      simplify the Kconfig logic, and easy drivers selection, especially
      for hybrid devices).  By confining all those renames there at 3.7
      it will cause all the harm at for media developers on just one
      shot.  Stable backports upstream and at distros will likely
      welcome it as well, as they won't need to check what changed on
      3.7 and what was postponed for on 3.8.

   2) The V4L2 DocBook Makefile creates a cross-reference between the
      media API headers and the specs.  This helps us _a_lot_ to be sure
      that all API improvements are properly documented.  Every time a
      header changes from one place to another, DocBook/media/Makefile
      needs to be patched.  Currently, the DocBook breakage patch
      depends on the DVB UAPI."

David Rientjes 4338584696 fs, xattr: fix bug when removing a name not in xattr list
Commit 38f3865744 ("xattr: extract simple_xattr code from tmpfs") moved
some code from tmpfs but introduced a subtle bug along the way.

If the name passed to simple_xattr_remove() does not exist in the list of
xattrs, then it is possible to call kfree(new_xattr) when new_xattr is
actually initialized to itself on the stack via uninitialized_var().

This causes a BUG() since the memory was not allocated via the slab
allocator and was not bypassed through to the page allocator because it
was too large.

Initialize the local variable to NULL so the kfree() never takes place.

Will Deacon 8f34a1da35 arm64: ptrace: use HW_BREAKPOINT_EMPTY type for disabled breakpoints
If a debugger tries to zero a hardware debug control register, the
kernel will try to infer both the type and length of the breakpoint
in order to sanity-check against the requested regset type. This will
fail because the encoding will appear as a zero-length breakpoint.

This patch changes the control register setting so that disabled
breakpoints are treated as HW_BREAKPOINT_EMPTY and no further
sanity-checking is required.

Catalin Marinas 16dd46bb78 arm64: No need to set the x0-x2 registers in start_thread()
For historical reasons, ARM used to set r0-r2 in start_thread() to the
first values on the user stack when starting a new user application. The
same logic has been inherited in AArch64. The x0 register is overridden
by the sys_execve() return value so it's always zero on success. The x1
and x2 registers are ignored by AArch64 and EABI AArch32 applications,
so we can safely remove the register setting for both native and compat
user space.

This also fixes a potential fault with the kernel accessing user space
stack directly.

Here's the first set of fixes for v3.7-rc cycle.
 
 DesignWare Core USB3 Driver (dwc3) got two fixes. The first one fixes a long
 standing bug which would keep endpoint with BUSY flag set forever if we cancel
 a transfer which has already been started by the controller. The second fix
 will just switch PHYs back off when DWC3 driver is removed.
 
 MUSB fixed a bug which would cause a Kernel Oops at least on AM3517 when
 removing a device. For some reason that particular device can fall into a
 situation where you have both Disconnect and Endpoint IRQs happen
 simultaneously (have both bits set in IRQ_STATUS register) and, because
 Disconnect Interrupt is handled before Endpoint Interrupts, we would try to
 transfer data over a disconnected device, thus generating a kernel oops.
 
 Renensas' USB DRD driver got two fixes which are a) fixing an off-by-one bug on
 the pipe iterator implementation and b) fixing Interrupt Status Clear procedure
 in order to properly clear a single Interrupt event without clearing (and
 masking) other events we didn't handle yet.

will just switch PHYs back off when DWC3 driver is removed.

MUSB fixed a bug which would cause a Kernel Oops at least on AM3517 when
removing a device. For some reason that particular device can fall into a
situation where you have both Disconnect and Endpoint IRQs happen
simultaneously (have both bits set in IRQ_STATUS register) and, because
Disconnect Interrupt is handled before Endpoint Interrupts, we would try to
transfer data over a disconnected device, thus generating a kernel oops.

Renensas' USB DRD driver got two fixes which are a) fixing an off-by-one bug on
the pipe iterator implementation and b) fixing Interrupt Status Clear procedure
in order to properly clear a single Interrupt event without clearing (and
masking) other events we didn't handle yet.

Johan Hovold 5d8c61bc28 USB: io_ti: fix sysfs-attribute creation
Make sure port data is initialised before creating sysfs attributes to
avoid a race.

A recent patch ("USB: io_ti: fix port-data memory leak") got the
sysfs-attribute creation and port-data initialisation ordering wrong.

Make sure sysfs attributes are created at port probe.

A recent patch ("USB: iuu_phoenix: fix port-data memory leak") removed
the sysfs-attribute creation by mistake.
