f89dec72e9 uvc_v4l2: Simplify compat ioctl implementation
The uvc compat ioctl implementation seems to have copied user data
for no good reason.  Remove a bunch of copies.

a44323e2a8 uvc: Forward compat ioctls to their handlers directly
The current code goes through a lot of indirection just to call a
known handler.  Simplify it: just call the handlers directly.

3d0f0b6a55 Merge branch 'for-linus-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs fixes from Chris Mason:
 "Has some fixes and some new self tests for btrfs.  The self tests are
  usually disabled in the .config file (unless you're doing btrfs dev
  work), and this bunch is meant to find problems with the 64K page size
  patches.

  Jeff has a patch to help people see if they are using the hardware
  assist crc32c module, which really helps us nail down problems when
  people ask why crcs are using so much CPU.

  Otherwise, it's small fixes"

  sched: panic on corrupted stack end

29d6455178 sched: panic on corrupted stack end
Until now, hitting this BUG_ON caused a recursive oops (because oops
handling involves do_exit(), which calls into the scheduler, which in
turn raises an oops), which caused stuff below the stack to be
overwritten until a panic happened (e.g.  via an oops in interrupt
context, caused by the overwritten CPU index in the thread_info).

Just panic directly.

2f36db7100 ecryptfs: forbid opening files without mmap handler

e54ad7f1ee proc: prevent stacking filesystems on top
This prevents stacking filesystems (ecryptfs and overlayfs) from using
procfs as lower filesystem.  There is too much magic going on inside
procfs, and there is no good reason to stack stuff on top of procfs.

(For example, procfs does access checks in VFS open handlers, and
ecryptfs by design calls open handlers from a kernel thread that doesn't
drop privileges or so.)

9d98bcec73 x86/ioapic: Fix incorrect pointers in ioapic_setup_resources()
On a 4-socket Brickland system, hot-removing one ioapic is fine.
Hot-removing the 2nd one causes panic in mp_unregister_ioapic()
while calling release_resource().

It is because the iomem_res pointer has already been released
when removing the first ioapic.

To explain the use of &res[num] here: res is assigned to ioapic_resources,
and later in ioapic_insert_resources() we do:

	struct resource *r = ioapic_resources;

        for_each_ioapic(i) {
                insert_resource(&iomem_resource, r);
                r++;
        }

Here 'r' is treated as an arry of 'struct resource', and the r++ ensures
that each element of the array is inserted separately. Thus we should call
release_resouce() on each element at &res[num].

Fix it by assigning the correct pointers to ioapics[i].iomem_res in
ioapic_setup_resources().

ef2bf4997f pwm: Improve args checking in pwm_apply_state()
It seems like in the process of refactoring pwm_config() to utilize the
newly-introduced pwm_apply_state() API, some args/bounds checking was
dropped.

In particular, I noted that we are now allowing invalid period
selections, e.g.:

  # echo 1 > /sys/class/pwm/pwmchip0/export
  # cat /sys/class/pwm/pwmchip0/pwm1/period
  100
  # echo 101 > /sys/class/pwm/pwmchip0/pwm1/duty_cycle
  [... driver may or may not reject the value, or trigger some logic bug ...]

It's better to see:

  # echo 1 > /sys/class/pwm/pwmchip0/export
  # cat /sys/class/pwm/pwmchip0/pwm1/period
  100
  # echo 101 > /sys/class/pwm/pwmchip0/pwm1/duty_cycle
  -bash: echo: write error: Invalid argument

This patch reintroduces some bounds checks in both pwm_config() (for its
signed parameters; we don't want to convert negative values into large
unsigned values) and in pwm_apply_state() (which fix the above described
behavior, as well as other potential API misuses).

aaee8c3c5c x86/entry/traps: Don't force in_interrupt() to return true in IST handlers
Forcing in_interrupt() to return true if we're not in a bona fide
interrupt confuses the softirq code.  This fixes warnings like:

  NOHZ: local_softirq_pending 282

... which can happen when running things like selftests/x86.

This will change perf's static percpu buffer usage in IST context.
I think this is okay, and it's changing the behavior to match
historical (pre-4.0) behavior.

356d27bbfe drm/i915: Extract physical display dimensions from VBT
The VBT has these mysterious H/V image sizes as part of the display
timings. Looking at some dumps those appear to be the physical
dimensions in mm. Which makes sense since the timing descriptor matches
the format used by EDID detailed timing descriptor, which defines these
as "H/V Addressable Video Image Size in mm".

So let's use that information from the panel fixed mode to get the
physical dimensions for LVDS/eDP/DSI displays. And with that we can
fill out the display_info so that userspace can get at it via
GetConnector.

v2: Use (hi<<8)|lo instead of broken (hi<<4)+lo
    Handle LVDS and eDP too

a5aac5ab87 drm/i915: Check VBT for port presence in addition to the strap on VLV/CHV
Apparently some CHV boards failed to hook up the port presence straps
for HDMI ports as well (earlier we assumed this problem only affected
eDP ports). So let's check the VBT in addition to the strap, and if
either one claims that the port is present go ahead and register the
relevant connector.

While at it, change port D to register DP before HDMI as we do for ports
B and C since
commit 457c52d87e ("drm/i915: Only ignore eDP ports that are connected")

Also print a debug message when we register a HDMI connector to aid
in diagnosing missing/incorrect ports. We already had such a print for
DP/eDP.

v2: Improve the comment in the code a bit, note the port D change in
    the commit message

fff7660d1e drm/i915: Only ignore eDP ports that are connected
If the VBT says that a certain port should be eDP (and hence fused off
from HDMI), but in reality it isn't, we need to try and acquire the HDMI
connection instead. So only trust the VBT edp setting if we can connect
to an eDP device on that port.

My old 845g complains that the child_device_size inside its VBT,

as v108).

Fixes [drm:intel_bios_init] *ERROR* Unexpected child device config

Whether this is correct, no one knows - but it works for this particular

719c44d340 packet: compat support for sock_fprog
Socket option PACKET_FANOUT_DATA takes a struct sock_fprog as argument
if PACKET_FANOUT has mode PACKET_FANOUT_CBPF. This structure contains
a pointer into user memory. If userland is 32-bit and kernel is 64-bit
the two disagree about the layout of struct sock_fprog.

Add compat setsockopt support to convert a 32-bit compat_sock_fprog to
a 64-bit sock_fprog. This is analogous to compat_sock_fprog support for
SO_REUSEPORT added in commit 1957598840 ("soreuseport: add compat

Saeed Mahameed says:

====================
Mellanox 100G mlx5 fixes for 4.7-rc

The following series provides some small fixes for mlx5 driver.

Two small fixes for the mlx5e netdev, the 1st is for the blue flame
quota accounting and the 2nd is a small refactoring in shutdown flow.

Five trivial fixes for mlx5 E-Switch.
	- Allmulti mc_promisc flag was not set in a specific flow.
	- Modify VF node guid when admin mac is changed.
	- Race in vport enable flow.
	- Misc code fixes (kvfree when needed and error pointers checking).

Three in mlx5 steering area.  Correct capabilities checking and root flow table update.

Three misc fixes in mlx5 commands enum and layouts.

0ca00fc1f8 net/mlx5e: Fix blue flame quota logic
Blue flame is a latency enhancement feature that allows the driver to
write the packet data directly to the NIC's registers thus making the
read of the packet data from host memory redundant.

We maintain a quota for the blue flame which is reloaded whenever we
identify that the hardware is processing send requests and processes
them fast enough so by the time we post the next send request it was
able to process all the pending ones. This indicates that the hardware
is capable of processing more blue flame requests efficiently. The blue
flame quota is decremented whenever we send using blue flame.

The current code erroneously clears the budget if we did not use blue
flame for the current post send operation and we fix it here.

23898c763f net/mlx5: E-Switch, Modify node guid on vf set MAC
In RoCE, the RDMA-CM needs the node guid to establish connection
between nodes.
Today, the node guid exposed to mlx5 Ethernet VFs is zero, therefore
RDMA-CM on the VF is broken.

Whenever the administrator sets a MAC for a VF, derive the node guid
from it and set it as well in the following way:
MAC: e4:1d:2d:b3:f4:01 -> node_guid: e4:1d:2d:ff:fe:b3:f4:01

25fff58cb2 net/mlx5: E-Switch, Fix vport enable flow
Reorder vport enable flow to mark the vport as enabled before calling
the vport change handler which was modified to handle the case for
when vport is not enabled.

This fixes the case for when the PF netdev is open before sriov is
enabled, once sriov is enabled at esw_enable_vport,
esw_vport_change_handle_locked didn't read the PF context since it
thought the PF vport was not enabled.

When we enable the vport, arming for events is not required anymore,
since it's done on the vport change handle

3f42ac6648 net/mlx5: E-Switch, Use the correct error check on returned pointers
The mlx5 flow-steering API (mlx5_create_flow_table/group/rule) never
returns null pointer on error. Even if it was doing that, checking
for IS_ERR_OR_NULL(p) and then returning PTR_ERR(p) would have cause
bugs, since PTR_ERR(NULL) --> success, crash.

To make things more robust and protect against related future bugs,
convert all IS_ERR_OR_NULL checks on returned values to IS_ERR.
