For certain arguments such as saddr = 0xc0a8fd60, daddr = 0xc0a8fda1,
len = 80, proto = 17, sum = 0x7eae049d there will be a carry when
folding the intermediate 64 bit checksum to 32 bit but the code doesn't
add the carry back to the one's complement sum, thus an incorrect result
will be generated.

For a shared reset, when the reset is successful, the triggered_count is
incremented when trying to call the reset callback, so that another device
sharing the same reset line won't trigger it again. If the reset has not
been triggered successfully, the trigger_count should be decremented.
The code does the opposite, and decrements the trigger_count on success.
As a consequence, another device sharing the reset will be able to trigger
it again.
Fixed be removing negation in from of the error code of the reset function.

Walking kernel page tables within the kernel page table dumper may
potentially take a lot of time. This may lead to soft lockup warning
messages.
To avoid this add a cond_resched call for each pgd_level iteration.

Historically a lot of these existed because we did not have
a distinction between what was modular code and what was providing
support to modules via EXPORT_SYMBOL and friends. That changed
when we forked out support for the latter into the export.h file.
This means we should be able to reduce the usage of module.h
in code that is obj-y Makefile or bool Kconfig. The advantage
in doing so is that module.h itself sources about 15 other headers;
adding significantly to what we feed cpp, and it can obscure what
headers we are effectively using.
Since module.h was the source for init.h (for __init) and for
export.h (for EXPORT_SYMBOL) we consider each change instance
for the presence of either and replace as needed. An instance
where module_param was used without moduleparam.h was also fixed,
as well as implicit use of ptrace.h and string.h headers.

In binutils/libbfd (bfd/elf.c) it is enforced that all s390 specific ELF
notes like e.g. NT_S390_PREFIX or NT_S390_CTRS have "LINUX" specified
as note name. Otherwise the notes are ignored.
For /proc/vmcore we currently use "CORE" for these notes.
Up to now this has not been a real problem because the dump analysis tool
"crash" does not check the note name. But it will break all programs that
use libbfd for processing ELF notes.
So fix this and use "LINUX" for all s390 specific notes to comply with
libbfd.

Commit df2cb6daa4 ("block: Avoid deadlocks with bio allocation by
stacking drivers") created a workqueue for every bio set and code
in bio_alloc_bioset() that tries to resolve some low-memory deadlocks
by redirecting bios queued on current->bio_list to the workqueue if the
system is low on memory. However other deadlocks (see below **) may
happen, without any low memory condition, because generic_make_request
is queuing bios to current->bio_list (rather than submitting them).
** the related dm-snapshot deadlock is detailed here:
https://www.redhat.com/archives/dm-devel/2016-July/msg00065.html
Fix this deadlock by redirecting any bios on current->bio_list to the
bio_set's rescue workqueue on every schedule() call. Consequently,
when the process blocks on a mutex, the bios queued on
current->bio_list are dispatched to independent workqueus and they can
complete without waiting for the mutex to be available.
The structure blk_plug contains an entry cb_list and this list can contain
arbitrary callback functions that are called when the process blocks.
To implement this fix DM (ab)uses the onstack plug's cb_list interface
to get its flush_current_bio_list() called at schedule() time.
This fixes the snapshot deadlock - if the map method blocks,
flush_current_bio_list() will be called and it redirects bios waiting
on current->bio_list to appropriate workqueues.

The sloppy nature of lockless access to percpu pointers
(s->current_path) in rr_select_path(), from multiple threads, is
causing some paths to used more than others -- which results in less
IO performance being observed.
Revert these upstream commits to restore truly symmetric round-robin
IO submission in DM multipath:
b0b477c dm round robin: use percpu 'repeat_count' and 'current_path'
802934b dm round robin: do not use this_cpu_ptr() without having preemption disabled
There is no benefit to all this complexity if repeat_count = 1 (which is
the recommended default).

10GbE Intel Wired LAN Driver Updates 2017-02-16
This series contains updates to ixgbe only.
Tony updates the driver to advertise 2.5Gb and 5.0Gb if the adapter
supports it.
Stephen Hemminger renames our dcbnl_ops since it is global to
ixgbe_dcbnl_ops to avoid namespace issues.
Mark updates the driver version based on the recent changes.
Alex has the remainder of the changes, starting with consolidating
functions that represent logical steps in the receive process so we can
later update them more easily (and align with igb). Modify the receive
path to only synchronize the length of the frame versus the entire buffer.
Provided performance improvements by adding support for
DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING. Also made additional
performance gains by batching the page count updates instead of doing
them one at a time. Adjusted the receive path to use 3k buffers with
8k backing them in order to support build_skb with jumbo frames. Made
additional driver improvements by using the length of the packet instead
of the DD status to determine if a new descriptor is ready to be
processed, which cuts down on reads. To reduce code duplication, pulled
apart the receive path into separate functions. Added support for
providing a buffer with headroom and tailroom to allow for shared info
for NET_SKB_PAD and NET_IP_ALIGN.

7bdb59f1ad47 ("tick/nohz: Fix possible missing clock reprog after tick

Pavel reports that it causes occasional boot hangs for him that seem to
depend on just how the machine was booted. In particular, his machine
hangs at around the PCI fixups of the EHCI USB host controller, but only
hangs from cold boot, not from a warm boot.
Thomas Gleixner suspecs it's a CPU hotplug interaction, particularly
since Pavel also saw suspend/resume issues that seem to be related.
We're reverting for now while trying to figure out the root cause.

Pull perf/core clang fixes from Arnaldo Carvalho de Melo:
Changes to make tools/{perf,lib/{bpf,traceevent,api}} build with
CC=clang, to, for instance, take advantage of warnings (Arnaldo Carvalho de Melo):
- Conditionally request some warning options not available on clang
- Set the maximum optimization level to -O3 when using CC=clang, leave
the previous setting of -O6 otherwise.
- Make it an error to pass a signed value to OPTION_UINTEGER, so that
we can remove abs(unsigned int) calls in 'perf bench futex'.
- Make sure dprintf() is not defined before using that name in 'perf bench numa'
- Avoid using field after variable sized type, its a GNU extension, use
equivalent code.
- Fix some bugs where some variables could be used unitialized,
something not caught by gcc.
- Fix some spots where we were testing struct->array[] members against
NULL, it will always evaluate to 'true'.
- Add missing parse_events_error() prototype in the bison file.

Enabling both DEBUG_WX=y and KASAN=y options significantly increases
boot time (dozens of seconds at least).
KASAN fills kernel page tables with repeated values to map several
TBs of the virtual memory to the single kasan_zero_page:
kasan_zero_pud ->
kasan_zero_pmd->
kasan_zero_pte->
kasan_zero_page
So, the page table walker used to find W+X mapping check the same
kasan_zero_p?d page table entries a lot more than once.
With patch pud walker will skip the pud if it has the same value as
the previous one . Skipping done iff we search for W+X mappings,
so this optimization won't affect the page table dump via debugfs.
This dropped time spend in W+X check from ~30 sec to reasonable 0.1 sec:
Before:
[ 4.579991] Freeing unused kernel memory: 1000K
[ 35.257523] x86/mm: Checked W+X mappings: passed, no W+X pages found.
After:
