Use is_zero_pfn() on pteval only after pte_present() check on pteval
(It might be better idea to introduce is_zero_pte() which checks
pte_present() first).
Otherwise when working on a swap or migration entry and if pte_pfn's
result is equal to zero_pfn by chance, we lose user's data in
__collapse_huge_page_copy(). So if you're unlucky, the application
segfaults and finally you could see below message on exit:

call_usermodehelper_exec_sync() does fork() + wait() with "unignored"
SIGCHLD. What we have missed is that this worker thread can have other
children previously forked by call_usermodehelper_exec_work() without
UMH_WAIT_PROC. If such a child exits in between it becomes a zombie
because auto-reaping only works if SIGCHLD is ignored, and nobody can
reap it (unless/until this worker thread exits too).
Change the !UMH_WAIT_PROC case to use CLONE_PARENT.
Note: this is only first step. All PF_KTHREAD tasks, even created by
kernel_thread() should have ->parent == kthreadd by default.

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
User visible changes:
- The default for callchains is back to 'callee' when --children is not used.
(Namhyung Kim)
- Move the 'use_offset' option to the right place where the annotate code
expects it to be to be able to properly handle it. (Namhyung Kim)
- Don't die when an unknown 'annotate' option is found in the perf config

We skip the header informations if the data pointer points
already behind the header in question for some protocols.
This is because we call pskb_may_pull with a negative value
converted to unsigened int from pskb_may_pull in this case.
Skipping the header informations can lead to incorrect policy
lookups, so fix it by a check of the data pointer position
before we call pskb_may_pull.

On sparc, deleting established SAs (e.g., by restarting ipsec)
results in unaligned access messages via xfrm_del_sa ->
km_state_notify -> xfrm_send_state_notify().
Even though struct xfrm_usersa_info is aligned on 8-byte boundaries,
netlink attributes are fundamentally only 4 byte aligned, and this
cannot be changed for nla_data() that is passed up to userspace.
As a result, the put_unaligned() macro needs to be used to
set up potentially unaligned fields such as the xfrm_stats in
copy_to_user_state()

While transitioning to netdev based vport we broke OVS
feature which allows user to retrieve tunnel packet egress
information for lwtunnel devices. Following patch fixes it
by introducing ndo operation to get the tunnel egress info.
Same ndo operation can be used for lwtunnel devices and compat
ovs-tnl-vport devices. So after adding such device operation
we can remove similar operation from ovs-vport.

Broadcom ethernet driver for the new family of NetXtreme-C/E
ethernet devices.
v5:
- Removed empty blank lines at end of files (noted by David Miller).
- Moved busy poll helper functions to bnxt.h to at least make the
.c file look less cluttered with #ifdef (noted by Stephen Hemminger).
v4:
- Broke up 2 long message strings with "\n" (suggested by John Linville)
- Constify an array of strings (suggested by Stephen Hemminger)
- Improve bnxt_vf_pciid() (suggested by Stephen Hemminger)
- Use PCI_VDEVICE() to populate pci_device_id table for more compact
source.
v3:
- Fixed 2 more sparse warnings.
- Removed some unused structures in .h files.
v2:
- Fixed all kbuild test robot reported warnings.
- Fixed many of the checkpatch.pl errors and warnings.
- Fixed the Kconfig description (noted by Dmitry Kravkov).

Intel Wired LAN Driver Updates 2015-10-22
This series contains fixes to i40e only.
Jesse provides two small fixes for i40e, first fixes counters that were
being displayed incorrectly due to indexing beyond the array of strings
when printing stats. Then fixed the fact that the driver was printing
a message about not being able to assign VMDq because a lack of MSI-X
vectors, when it was not true. It was due to a line missing that

The perf_config() infrastructure we inherited from git calls die() when
the provided config callback returns -1, meaning some key in a config
section is unexpected, that seems ok for a stdio based tool, but in
--tui we end up messing up the output, so just tell the user about the
error, wait for a keystroke and return 0, being more resilient and
proceeding with what we managed to parse.
That die() needs to die, tho :-)

The variable err was never initialized, that means we had been checking
a garbage value in the for loop. Moreover if the segment is not outside
the firmware file then also we have been returning the garbage.
Initialize it to 0 so that on success we return the value and no need to
check in the for loop also as it is initially 0 and whenever that value
changes we have done a break from the loop.

static analysis with cppcheck detected the following error:
[drivers/media/platform/sti/c8sectpfe/c8sectpfe-core.c:1210]:
(error) Uninitialized variable: ret
ret is never initialised, so garbage is being returned. Instead
return the error return from the call of request_firmware_nowait

If CONFIG_DVB_LNBH25 is disabled, a stub static inline function is
defined that just prints a warning about the driver being disabled
but the function return type was wrong which caused a build error.

The keyboard driver for GPIO buttons(gpio-keys) checks for one of the
two boolean properties to enable gpio buttons as wakeup source:
1. "wakeup-source" or
2. the legacy "gpio-key,wakeup"
However juno, ste-snowball and emev2-kzm9d dts file have a undetected
"wakeup" property to indictate the wakeup source.
This patch fixes it by making use of "wakeup-source" property.

====================
pull request (net): ipsec 2015-10-22
1) Fix IPsec pre-encap fragmentation for GSO packets.
From Herbert Xu.
2) Fix some header checks in _decode_session6.
We skip the header informations if the data pointer points
already behind the header in question for some protocols.
This is because we call pskb_may_pull with a negative value
converted to unsigened int from pskb_may_pull in this case.
Skipping the header informations can lead to incorrect policy
lookups. From Mathias Krause.
3) Allow to change the replay threshold and expiry timer of a
state without having to set other attributes like replay
counter and byte lifetime. Changing these other attributes
may break the SA. From Michael Rossberg.
4) Fix pmtu discovery for local generated packets.
We may fail dispatch to the inner address family.
As a reault, the local error handler is not called
and the mtu value is not reported back to userspace.
Please pull or let me know if there are problems.

net: dsa: implement port_fdb_dump in drivers
Not all switch chips provide a Get Next kind of operation to dump FDB entries.
It is preferred to let the driver handle the dump operation the way it works
best for the chip. Thus, drop port_fdb_getnext and implement the port_fdb_dump
operation in DSA, which pushes the switchdev FDB dump callback down to the
drivers. mv88e6xxx is the only driver affected and is updated accordingly.
v3 -> v4: fix rejects on latest net-next
v2 -> v3: opencode switchdev_obj_dump_cb_t to avoid multiple typedef;
use ether_addr_copy in fdb_dump
v1 -> v2: fix a few "return err" instead of "goto unlock" in mv88e6xxx.c
====================

No driver implements port_fdb_getnext anymore, and port_fdb_dump is
preferred anyway, so remove this function from DSA.

There is no need to write the MAC address before every Get Next
operation, since ATU MAC registers are not cleared between calls.
Move the _mv88e6xxx_atu_mac_write call outside of _mv88e6xxx_atu_getnext
so future code could call ATU Get Next multiple times and save a few
register access.
