When CPUs start and stop the watchdog, they manipulate shared data

When the SMP detector finds other CPUs stuck, it iterates over
them and marks them as stuck. This pulls them out of the pending
mask and allows the detector to continue with remaining good
CPUs (if nmi_watchdog=panic is not enabled).
The code to dothat was buggy because when setting a CPU stuck,
if the pending mask became empty, it resets it to keep the
watchdog running. However the iterator will continue to run
over the new pending mask and mark remaining good CPUs sas stuck.
Fix this by doing it with cpumask bitwise operations.

Some code can go into a tight loop calling touch_nmi_watchdog (e.g.,
stop_machine CPU hotplug code). This can cause contention on watchdog
locks particularly if all CPUs with watchdog enabled are spinning in
the loops.
Avoid this storm of activity by running the watchdog timer callback
from this path if we have exceeded the timer period since it was last
run.

- Hard-disable interrupts before taking the lock, which prevents
soft-NMI re-entrancy and therefore can prevent deadlocks.
- Use raw_ variants of local_irq_disable to avoid irq debugging.
- When the lock is contended, spin at low SMT priority, using
loads only, and with interrupts enabled (where possible).
Some stalls have been noticed at high loads that go away with improved
locking. There should not be so much locking contention in the first
place (which is addressed in a subsequent patch), but locking should
still be improved.

CONFIG_LOCKUP_DETECTOR was split into two separate config options,
CONFIG_HARDLOCKUP_DETECTOR and CONFIG_SOFTLOCKUP_DETECTOR.
Our defconfigs still have CONFIG_LOCKUP_DETECTOR=y, but that is no longer
user selectable, and we don't mention the new options, so we end up with
none of them enabled.
So update the defconfigs to turn on the new SOFT and HARD options, the

skb_warn_bad_offload triggers a warning when an skb enters the GSO
stack at __skb_gso_segment that does not have CHECKSUM_PARTIAL
checksum offload set.
Commit b2504a5dbe ("net: reduce skb_warn_bad_offload() noise")
observed that SKB_GSO_DODGY producers can trigger the check and
that passing those packets through the GSO handlers will fix it
up. But, the software UFO handler will set ip_summed to
CHECKSUM_NONE.
When __skb_gso_segment is called from the receive path, this
triggers the warning again.
Make UFO set CHECKSUM_UNNECESSARY instead of CHECKSUM_NONE. On
Tx these two are equivalent. On Rx, this better matches the
skb state (checksum computed), as CHECKSUM_NONE here means no
checksum computed.

Commit e5dadc65f9 ("ppp: Fix false xmit recursion detect with two ppp
devices") dropped the xmit_recursion counter incrementation in
ppp_channel_push() and relied on ppp_xmit_process() for this task.
But __ppp_channel_push() can also send packets directly (using the
.start_xmit() channel callback), in which case the xmit_recursion
counter isn't incremented anymore. If such packets get routed back to
the parent ppp unit, ppp_xmit_process() won't notice the recursion and
will call ppp_channel_push() on the same channel, effectively creating
the deadlock situation that the xmit_recursion mechanism was supposed
to prevent.
This patch re-introduces the xmit_recursion counter incrementation in
ppp_channel_push(). Since the xmit_recursion variable is now part of
the parent ppp unit, incrementation is skipped if the channel doesn't
have any. This is fine because only packets routed through the parent
unit may enter the channel recursively.
Finally, we have to ensure that pch->ppp is not going to be modified
while executing ppp_channel_push(). Instead of taking this lock only
while calling ppp_xmit_process(), we now have to hold it for the full
ppp_channel_push() execution. This respects the ppp locks ordering
which requires locking ->upl before ->downl.

Allow any number of command line arguments to match either the
section header or the section contents and create new files.
Create MAINTAINERS.new and SECTION.new.
This allows scripting of the movement of various sections from
MAINTAINERS.

Instead of reading STDIN and writing STDOUT, use specific filenames of
MAINTAINERS and MAINTAINERS.new.
Use hash references instead of global hash %hash so future modifications
can read and write specific hashes to split up MAINTAINERS into multiple

Section [A-Z]: patterns are not currently in any required sorting order.
Add a specific sorting sequence to MAINTAINERS entries.
Sort F: and X: patterns in alphabetic order.
The preferred section ordering is:
SECTION HEADER
M: Maintainers
R: Reviewers
P: Named persons without email addresses
L: Mailing list addresses
S: Status of this section (Supported, Maintained, Orphan, etc...)
W: Any relevant URLs
T: Source code control type (git, quilt, etc)
Q: Patchwork patch acceptance queue site
B: Bug tracking URIs
C: Chat URIs
F: Files with wildcard patterns (alphabetic ordered)
X: Excluded files with wildcard patterns (alphabetic ordered)
N: Files with regex patterns
K: Keyword regexes in source code for maintainership identification
Miscellaneous perl neatening:
- Rename %map to %hash, map has a different meaning in perl
- Avoid using \& and local variables for function indirection
- Use return for a little c like clarity
- Use c-like function call style instead of &function

Allow for MAINTAINERS to become a directory and if it is,
read all the files in the directory for maintained sections.
Optionally look for all files named MAINTAINERS in directories
excluding the .git directory by using --find-maintainer-files.
This optional feature adds ~.3 seconds of CPU on an Intel
i5-6200 with an SSD.
Miscellanea:
- Create a read_maintainer_file subroutine from the existing code
- Test only the existence of MAINTAINERS, not whether it's a file

Fix the warning message on the parisc and IA64 architectures to show the
correct function name of the caller by using %pS instead of %pF. The
message is printed with the value of _RET_IP_ which calls
__builtin_return_address(0) and as such returns the IP address caller
instead of pointer to a function descriptor of the caller.
The effect of this patch is visible on the parisc and ia64 architectures
only since those are the ones which use function descriptors while on
all others %pS and %pF will behave the same.

As we may have just bound the renderstate into the GGTT for execution, we
need to ensure that the GTT TLB are also flushed.
On snb-gt2, this would cause a random GPU hang at the start of a new
context (e.g. boot) and on snb-gt1, it was causing the renderstate batch
to take ~10s. It was the GPU hang that revealed the truth, as the CS
gleefully executed beyond the end of the golden renderstate batch, a good
indicator for a GTT TLB miss.
