Felipe Balbi 66e4afc77f usb: gadget: pxa25x: fix disconnect reporting
when commit 6166c24 (usb: gadget: pxa25x_udc:
convert to udc_start/udc_stop) converted
this driver to udc_start/udc_stop, it failed
to consider the fact that stop_activity()
is called from disconnect interrupt.

Fix the problem so that gadget drivers know
about proper disconnect sequences.

Li Zefan cb16b91a44 s390: Fix a header dependencies related build error
Commit 877c685607
("perf: Remove include of cgroup.h from perf_event.h") caused
this build failure if PERF_EVENTS is enabled:

   In file included from arch/s390/include/asm/perf_event.h:9:0,

cpu_mf.h had an implicit errno.h dependency, which was added
indirectly via cgroups.h but not anymore. Add it explicitly.

Mark Brown 4b7d293c64 Input: mms114 - Fix regulator enable and disable paths
When it uses regulators the mms114 driver checks to see if it managed to
acquire regulators and ignores errors. This is not the intended usage and
not great style in general.

Since the driver already refuses to probe if it fails to allocate the
regulators simply make the enable and disable calls unconditional and
add appropriate error handling, including adding cleanup of the
regulators if setup_reg() fails.

Mathias Krause 29cd8ae0e1 dcbnl: fix various netlink info leaks

* perm_addr[] buffer is only filled at max with 12 of the 32 bytes but
  copied completely,
* no in-kernel driver fills all fields of an IEEE 802.1Qaz subcommand,
  so we're leaking up to 58 bytes for ieee_ets structs, up to 136 bytes
  for ieee_pfc structs, etc.,
* the same is true for CEE -- no in-kernel driver fills the whole
  struct,

Prevent all of the above stack info leaks by properly initializing the
buffers/structures involved.

Not that I want my dirty fingers near that beautiful screen, but it
seems that a non-initialized touchscreen will also end up being a

Eric W. Biederman db04dc679b proc: Use nd_jump_link in proc_ns_follow_link
Update proc_ns_follow_link to use nd_jump_link instead of just
manually updating nd.path.dentry.

This fixes the BUG_ON(nd->inode != parent->d_inode) reported by Dave
Jones and reproduced trivially with mkdir /proc/self/ns/uts/a.

Sigh it looks like the VFS change to require use of nd_jump_link
happend while proc_ns_follow_link was baking and since the common case
of proc_ns_follow_link continued to work without problems the need for
making this change was overlooked.

Benson Leung 2ef392042d Platform: x86: chromeos_laptop : Add basic platform data for atmel devices
Add basic platform data to get the current upstream driver working
with the 224s touchpad and 1664s touchscreen.
We will be using NULL config so we will use the settings from the
devices' NVRAMs.

Daniel Kurtz 22dfab7fd7 Input: atmel_mxt_ts - Support for touchpad variant
This same driver can be used by atmel based touchscreens and touchpads
(buttonpads). Platform data may specify a device is a touchpad
using the is_tp flag.

This will cause the driver to perform some touchpad specific
initializations, such as:
  * register input device name "Atmel maXTouch Touchpad" instead of
  Touchscreen.
  * register BTN_LEFT & BTN_TOOL_* event types.
  * register axis resolution (as a fixed constant, for now)
  * register BUTTONPAD property
  * process GPIO buttons using reportid T19

Input event GPIO mapping is done by the platform data key_map array.

key_map[x] should contain the KEY or BTN code to send when processing
GPIOx from T19. To specify a GPIO as not an input source, populate
with KEY_RESERVED, or 0.

Hugh Dickins d8fc16a825 ksm: fix m68k build: only NUMA needs pfn_to_nid
A CONFIG_DISCONTIGMEM=y m68k config gave

  mm/ksm.c: In function `get_kpfn_nid':
  mm/ksm.c:492: error: implicit declaration of function `pfn_to_nid'

linux/mmzone.h declares it for CONFIG_SPARSEMEM and CONFIG_FLATMEM, but
expects the arch's asm/mmzone.h to declare it for CONFIG_DISCONTIGMEM
(see arch/mips/include/asm/mmzone.h for example).

Or perhaps it is only expected when CONFIG_NUMA=y: too much of a maze,
and m68k got away without it so far, so fix the build in mm/ksm.c.

Ben Hutchings a40e7cf8f0 dmi_scan: fix missing check for _DMI_ signature in smbios_present()
Commit 9f9c9cbb60 ("drivers/firmware/dmi_scan.c: fetch dmi version
from SMBIOS if it exists") hoisted the check for "_DMI_" into
dmi_scan_machine(), which means that we don't bother to check for
"_DMI_" at offset 16 in an SMBIOS entry.  smbios_present() may also call
dmi_present() for an address where we found "_SM_", if it failed further
validation.

Check for "_DMI_" in smbios_present() before calling dmi_present().

Tejun Heo 2e1c9b2867 idr: remove WARN_ON_ONCE() on negative IDs
idr_find(), idr_remove() and idr_replace() used to silently ignore the
sign bit and perform lookup with the rest of the bits.  The weird behavior
has been changed such that negative IDs are treated as invalid.  As the
behavior change was subtle, WARN_ON_ONCE() was added in the hope of
determining who's calling idr functions with negative IDs so that they can
be examined for problems.

Up until now, all two reported cases are ID number coming directly from
userland and getting fed into idr_find() and the warnings seem to cause
more problems than being helpful.  Drop the WARN_ON_ONCE()s.
