Some of the sample files are causing issues when they are loaded with tc
and cls_bpf, meaning tc bails out while trying to parse the resulting ELF
file as program/map/etc sections are not present, which can be easily
spotted with readelf(1).
Currently, BPF samples are including some of the kernel headers and mid
term we should change them to refrain from this, really. When dynamic
debugging is enabled, we bail out due to undeclared KBUILD_MODNAME, which
is easily overlooked in the build as clang spills this along with other
noisy warnings from various header includes, and llc still generates an
ELF file with mentioned characteristics. For just playing around with BPF
examples, this can be a bit of a hurdle to take.
Just add a fake KBUILD_MODNAME as a band-aid to fix the issue, same is
done in xdp*_kern samples already.

Mellanox 100G mlx5 fixes 2016-10-25
This series contains some bug fixes for the mlx5 core and mlx5e driver.
From Daniel:
- Cache line size determination at runtime, instead of using
L1_CACHE_BYTES hard coded value, use cache_line_size()
- Always Query HCA caps after setting them even on reset flow
From Mohamad:
- Reorder netdev cleanup to uregister netdev before detaching it
for the kernel to not complain about open resources such as vlans
- Change the acl enable prototype to return status, for better error
resiliency
- Clear health sick bit when starting health poll after reset flow
- Fix race between PCI error handlers and health work
- PCI error recovery health care simulation, in case when the kernel
PCI error handlers are not triggered for some internal firmware errors
From Noa:
- Avoid passing dma address 0 to firmware when mapping system pages
to the firmware
From Paul: Some straight forward flow steering fixes
- Keep autogroups list ordered
- Fix autogroups groups num not decreasing
- Correctly initialize last use of flow counters
From Saeed:
- Choose the nearest LRO timeout to the wanted one
instead of blindly choosing "dev_cap.lro_timeout[2]"
This series has no conflict with the for-next pull request posted
earlier today ("Mellanox mlx5 core driver updates 2016-10-25").

Currently the firmware can't work with a page with dma address 0.
Passing such an address to the firmware will cause the give_pages
command to fail.
To avoid this, in case we get a 0 dma address of a page from the
dma engine, we avoid passing it to FW by remapping to get an address
other than 0.

In case that the kernel PCI error handlers are not called, we will
trigger our own recovery flow.
The health work will give priority to the kernel pci error handlers to
recover the PCI by waiting for a small period, if the pci error handlers
are not triggered the manual recovery flow will be executed.
We don't save pci state in case of manual recovery because it will ruin the
pci configuration space and we will lose dma sync.

Currently there is a race between the health care work and the kernel
pci error handlers because both of them detect the error, the first one
to be called will do the error handling.
There is a chance that health care will disable the pci after resuming
pci slot.
Also create a separate WQ because now we will have two types of health
works, one for the error detection and one for the recovery.

Andrey Konovalov reported that KASAN detected that SCTP was using a slab
beyond the boundaries. It was caused because when handling out of the
blue packets in function sctp_sf_ootb() it was checking the chunk len
only after already processing the first chunk, validating only for the
2nd and subsequent ones.
The fix is to just move the check upwards so it's also validated for the
1st chunk.

The recent changes, which forced the registration of the boot cpu on UP
systems, which do not have ACPI tables, have been fixed for systems w/o
local APIC, but left a wreckage for systems which have neither ACPI nor
mptables, but the CPU has an APIC, e.g. virtualbox.
The boot process crashes in prefill_possible_map() as it wants to register
the boot cpu, which needs to access the local apic, but the local APIC is
not yet mapped.
There is no reason why init_apic_mapping() can't be invoked before
prefill_possible_map(). So instead of playing another silly early mapping
game, as the ACPI/mptables code does, we just move init_apic_mapping()
before the call to prefill_possible_map().
In hindsight, I should have noticed that combination earlier.
Sorry for the churn (also in stable)!

mddev->curr_resync usually records where the current resync is up to,
but during the starting phase it has some "magic" values.
1 - means that the array is trying to start a resync, but has yielded
to another array which shares physical devices, and also needs to
start a resync
2 - means the array is trying to start resync, but has found another
array which shares physical devices and has already started resync.
3 - means that resync has commensed, but it is possible that nothing
has actually been resynced yet.
It is important that this value not be visible to user-space and
particularly that it doesn't get written to the metadata, as the
resync or recovery checkpoint. In part, this is because it may be
slightly higher than the correct value, though this is very rare.
In part, because it is not a multiple of 4K, and some devices only
support 4K aligned accesses.
There are two places where this value is propagates into either
->curr_resync_completed or ->recovery_cp or ->recovery_offset.
These currently avoid the propagation of values 1 and 3, but will
allow 3 to leak through.
Change them to only propagate the value if it is > 3.
As this can cause an array to fail, the patch is suitable for -stable.

If write is the first operation on a disk and it happens not to be
aligned to page size, block layer sends read request first. If read
operation fails, the disk is set as failed as no attempt to fix the
error is made because array is in auto-readonly mode. Similarily, the
disk is set as failed for read-only array.
Take the same approach as in raid10. Don't fail the disk if array is in
readonly or auto-readonly mode. Try to redirect the request first and if
unsuccessful, return a read error.

The last step of the method termination should be the end of the method
serialization. Otherwise, the steps happening after it will face the race
issues that cannot be protected by the method serialization mechanism.
This patch fixes this issue by moving the per-method-object deletion code
prior than the end of the method serialization. Otherwise, the possible
race issues may result in AE_ALREADY_EXISTS error in a parallel

"Fix four timer locking races: two were noticed by Linus while
reviewing the code while chasing for a corruption bug, and two
from fixing spurious USB timeouts"

Only trees which are in use should be compared to requested prefix usage.

Currently, the prefix bitlist is not saved for LPM trees, causing the
compare to always fail which causes the tree to be destroyed and created
for every inserted and removed FIB entry. So fix this by saving
the bitlist as it should have been done from the very beginning.

commit 73e705bf81 ("regulator: core: Add set_voltage_time op")
introduced a new rdev_warn() if the ramp_delay is 0.
Apparently, on omap3/twl4030 platforms with dynamic voltage
management this results in non-ending spurious messages like
[ 511.143066] VDD1: ramp_delay not set
[ 511.662322] VDD1: ramp_delay not set
[ 513.903625] VDD1: ramp_delay not set

I have observed this on GTA04 while it is reported to occur on
N900 as well: https://bugzilla.kernel.org/show_bug.cgi?id=178371
This patch makes the warning appear only in debugging mode.
