When using CALIPSO with IPPROTO_UDP it is possible to trigger a GPF as the
IP header may have moved.
Also update the payload length after adding the CALIPSO option.

Intel Wired LAN Driver Updates 2017-06-06
This series contains fixes to i40e and i40evf only.
Mauro S. M. Rodrigues fixes a flood in the kernel log which was introduced
in a previous commit because of a mistaken substitution of __I40E_VSI_DOWN
instead of __I40E_DOWN when testing the state of the PF.
Björn Töpel fixes an issue introduced in a previous commit where the
offset was incorrect and could lead to data corruption for architectures
using PAGE_SIZE larger than 8191. Fixed the issue by updating the
page_offset correctly using the proper setting for truesize.

Commit 0da36b9774cc ("i40e: use DECLARE_BITMAP for state fields")
introduced changes in the way i40e works with state flags converting
them to bitmaps using kernel bitmap API. This change introduced a
regression due to a mistaken substitution using __I40E_VSI_DOWN instead
of __I40E_DOWN when testing state of a PF at i40e_reset_subtask()
function. This caused a flood in the kernel log with the follow message:
[49.013] i40e 0002:01:00.0: bad reset request 0x00000020
Commit d19cb64b9222 ("i40e: separate PF and VSI state flags")
also introduced some misuse of the VSI and PF flags, so both could be
considered as the offenders.
This patch simply fixes the flags where it makes sense by changing
__I40E_VSI_DOWN to __I40E_DOWN.

When we want to stop the recording of the firmware debug
and restart it later without reloading the firmware we
don't need to resend the configuration that comes with
host commands.
Sending those commands confused the hardware and led to
an NMI 0x66.
Change the flow as following:
* read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL)
* clear those registers
* wait for the hardware to complete its write to the buffer
* get the data
* restore the value of those registers (to restart the
recording)
For early start (where the configuration is already
compiled in the firmware), we don't need to set those
registers after the firmware has been loaded, but only
when we want to restart the recording without having
restarted the firmware.

Up until now, the driver was comparing the rate reported by the FW and
the rate of the latest LQ command to avoid processing data belonging
to the old LQ command. Recently, FW changed the meaning of the initial
rate field in tx response and it holds the actual rate (which is not
necessarily the initial rate of LQ's rate table). Use instead LQ cmd
color to be able to filter out tx responses/BA notifications which
where sent during earlier LQ commands' time frame.
This fixes some throughput degradation in noisy environments.

As reported by Patrice, the header layout of the decompressor is
incorrect when building for v7-M. In this case, the __nop macro
resolves to 'mov r0, r0', which is emitted as a narrow encoding,
resulting in the header data fields to end up at lower offsets than
required.
Given the variety of targets we need to support with the same code,
the startup sequence is a bit of a jumble, and uses instructions
and macros whose encoding widths cannot be specified (badr), or only
exist in a narrow encoding (bx)
So force the use of a wide encoding in __nop, and replace the start
sequence with a simple jump to the label marking the start of code,
preceded by a Thumb2 mode switch if required (using explicit wide
encodings where appropriate). The label itself can be moved to the
start of code [where it belongs] due to the larger range of branch
instructions as compared to adr instructions.

Commit 9520ed8fb841 ("net: dsa: use cpu_switch instead of ds[0]")
replaced the use of dst->ds[0] with dst->cpu_switch since that is
functionally equivalent, however, we can now run into an use after free
scenario after unbinding then rebinding the switch driver.
The use after free happens because we do correctly initialize
dst->cpu_switch the first time we probe in dsa_cpu_parse(), then we
unbind the driver: dsa_dst_unapply() is called, and we rebind again.
dst->cpu_switch now points to a freed "ds" structure, and so when we
finally dereference it in dsa_cpu_port_ethtool_setup(), we oops.
To fix this, simply set dst->cpu_switch to NULL in dsa_dst_unapply()
which guarantees that we always correctly re-assign dst->cpu_switch in
dsa_cpu_parse().

actually because orders larger than that are costly. And even that

This fixes a problem with reading files larger than 2GB from a UFS-2
file system:
https://bugzilla.kernel.org/show_bug.cgi?id=195721
The incorrect UFS s_maxsize limit became a problem as of commit
c2a9737f45e2 ("vfs,mm: fix a dead loop in truncate_inode_pages_range()")
which started using s_maxbytes to avoid a page index overflow in
do_generic_file_read().
That caused files to be truncated on UFS-2 file systems because the
default maximum file size is 2GB (MAX_NON_LFS) and UFS didn't update it.
Here I simply increase the default to a common value used by other file
systems.

Use software polling (PHY_POLL) to check for link state changes instead
of relying on the EMAC's hardware polling feature. Some PHY drivers
are unable to get a functioning link because the HW polling is not
robust enough.
The EMAC is able to poll the PHY on the MDIO bus looking for link state
changes (via the Link Status bit in the Status Register at address 0x1).
When the link state changes, the EMAC triggers an interrupt and tells the
driver what the new state is. The feature eliminates the need for
software to poll the MDIO bus.
Unfortunately, this feature is incompatible with phylib, because it
ignores everything that the PHY core and PHY drivers are trying to do.
In particular:
1. It assumes a compatible register set, so PHYs with different registers
may not work.
2. It doesn't allow for hardware errata that have work-arounds implemented
in the PHY driver.
3. It doesn't support multiple register pages. If the PHY core switches
the register set to another page, the EMAC won't know the page has
changed and will still attempt to read the same PHY register.
4. It only checks the copper side of the link, not the SGMII side. Some
PHY drivers (e.g. at803x) may also check the SGMII side, and
report the link as not ready during autonegotiation if the SGMII link
is still down. Phylib then waits for another interrupt to query
the PHY again, but the EMAC won't send another interrupt because it
thinks the link is up.

Right after I reverted this in my tree, it seems like another
"correct" fix might have shown up, but it's too late in the release
cycle to be messing with tty core locking, so let's just revert this
for now to go back how things always have been and try it again for
4.13.
This has not been in linux-next as I only reverted it a few hours ago"

Pull input subsystem fixes from Dmitry Torokhov:
- a couple of regression fixes in synaptics and axp20x-pek drivers
- try to ease transition from PS/2 to RMI for Synaptics touchpad users
by ensuring we do not try to activate RMI mode when RMI SMBus support
is not enabled, and nag users a bit to enable it
- plus a couple of other changes that seemed worthwhile for this
release
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: axp20x-pek - switch to acpi_dev_present and check for ACPI0011 too
Input: axp20x-pek - only check for "INTCFD9" ACPI device on Cherry Trail
Input: tm2-touchkey - use LEN_ON as boolean value instead of LED_FULL
Input: synaptics - tell users to report when they should be using rmi-smbus
Input: synaptics - warn the users when there is a better mode
Input: synaptics - keep PS/2 around when RMI4_SMB is not enabled
Input: synaptics - clear device info before filling in
Input: silead - disable interrupt during suspend

Pull RTC fixlet from Alexandre Belloni:
"A single patch, not really a fix but I don't think there is any reason
to delay it.
Change the mailing list address"

A rc device can call ir_raw_event_handle() after rc_allocate_device(),
but before rc_register_device() has completed. This is racey because
rcdev->raw is set before rcdev->raw->thread has a valid value.

Just depend on DEBUG_FS, no need to invent a new kernel config.
Especially since CEC can be enabled by drm without enabling
MEDIA_SUPPORT.

This config option is strictly speaking independent of the
media subsystem since it can be used by drm as well.
Besides, it looks odd when drivers select CEC_CORE and
MEDIA_CEC_NOTIFIER, that's inconsistent naming.

The CEC framework is used by both drm and media. That makes it tricky
to get the dependencies right.
This patch moves the CEC_CORE and MEDIA_CEC_NOTIFIER config options
out of the media menu and instead drivers that want to use CEC should
select CEC_CORE and MEDIA_CEC_NOTIFIER (if needed).

exit_loop is not being initialized, so it contains garbage. Ensure it is
