patch(1) loses the x bit. So if a user follows our patching
instructions in Documentation/admin-guide/README.rst, their kernel will

Depending on configuration mem_section can now be an array or a pointer
to an array allocated dynamically. In most cases, we can continue to
refer to it as 'mem_section' regardless of what it is.
But there's one exception: '&mem_section' means "address of the array"
if mem_section is an array, but if mem_section is a pointer, it would
mean "address of the pointer".
We've stepped onto this in kdump code. VMCOREINFO_SYMBOL(mem_section)
writes down address of pointer into vmcoreinfo, not array as we wanted.
Let's introduce VMCOREINFO_SYMBOL_ARRAY() that would handle the
situation correctly for both cases.

kmemleak does one slab allocation per user allocation. So if slab fault
injection is enabled to any degree, kmemleak instantly fails to allocate
and turns itself off. However, it's useful to use kmemleak with fault
injection to find leaks on error paths. On the other hand, checking
kmemleak itself is not so useful because (1) it's a debugging tool and
(2) it has a very regular allocation pattern (basically a single
allocation site, so it either works or not).
Turn off fault injection for kmemleak allocations.

This tests that the vsyscall entries do what they're expected to do.
It also confirms that attempts to read the vsyscall page behave as
expected.
If changes are made to the vsyscall code or its memory map handling,
running this test in all three of vsyscall=none, vsyscall=emulate,
and vsyscall=native are helpful.
(Because it's easy, this also compares the vsyscall results to their
vDSO equivalents.)
Note to KAISER backporters: please test this under all three
vsyscall modes. Also, in the emulate and native modes, make sure
that test_vsyscall_64 agrees with the command line or config
option as to which mode you're in. It's quite easy to mess up
the kernel such that native mode accidentally emulates
or vice versa.
Greg, etc: please backport this to all your Meltdown-patched
kernels. It'll help make sure the patches didn't regress
vsyscalls.

The intended behaviour in apparmor profile matching is to flag a
conflict if two profiles match equally well. However, right now a
conflict is generated if another profile has the same match length even
if that profile doesn't actually match. Fix the logic so we only
generate a conflict if the profiles match.

Given a label with a profile stack of
A//&B or A//&C ...
A ptrace rule should be able to specify a generic trace pattern with
a rule like
ptrace trace A//&**,
however this is failing because while the correct label match routine
is called, it is being done post label decomposition so it is always
being done against a profile instead of the stacked label.
To fix this refactor the cross check to pass the full peer label in to
the label_match.

Mellanox, mlx5 fixes 2018-01-11
The following series includes fixes to mlx5 core and netdev driver.
To highlight we have two critical fixes in this series:
1st patch from Eran to address a fix for Host2BMC Breakage.
2nd patch from Saeed to address the RDMA IRQ vector affinity settings query
issue, the patch provides the correct mlx5_core implementation for RDMA to
correctly query vector affinity.
I sent this patch privately to Sagi a week a go, so he could to test it
but I didn't hear from him.
All other patches are trivial misc fixes.
Please pull and let me know if there's any problem.
for -stable v4.14-y and later:
("net/mlx5: Fix get vector affinity helper function")
("{net,ib}/mlx5: Don't disable local loopback multicast traffic when needed")
Note: Merging this series with net-next will produce the following conflict:
<<<<<<< HEAD

Commit 3d1ad640f8c94 ("KVM: arm/arm64: Fix GICv4 ITS initialization
issues") moved the vgic_supports_direct_msis() check in vgic_v4_init().
However when vgic_v4_init is called from vgic_its_create(), the has_its
field is not yet set. Hence vgic_supports_direct_msis returns false and
vgic_v4_init does nothing.
The gic/its init sequence is a bit messy, so let's be specific about the
prerequisite checks in the various call paths instead of relying on a
common wrapper.

The fix for handling two-finger scroll (i4a646580f793 - "Input: ALPS -
fix two-finger scroll breakage in right side on ALPS touchpad")
introduced a minor "typo" that broke decoding of multi-touch events are
decoded on some ALPS touchpads. For example, tapping with three-fingers
can no longer be used to emulate middle-mouse-button (the kernel doesn't
recognize this as the proper event, and doesn't report it correctly to
userspace). This affects touchpads that use SS4 "plus" protocol
variant, like those found on Dell E7270 & E7470 laptops (tested on
E7270).
First, probably the code in alps_decode_ss4_v2() for case
SS4_PACKET_ID_MULTI used inconsistent indices to "f->mt[]". You can see
0 & 1 are used for the "if" part but 2 & 3 are used for the "else" part.
Second, in the previous patch, new macros were introduced to decode X
coordinates specific to the SS4 "plus" variant, but the macro to
define the maximum X value wasn't changed accordingly. The macros to
decode X values for "plus" variant are effectively shifted right by 1
bit, but the max wasn't shifted too. This causes the driver to
incorrectly handle "no data" cases, which also interfered with how
multi-touch was handled.

Allwinner fixes for 4.15, round 2
One fix that fixes the display pipeline description in the device tree
for the A10 and A20 SoCs. This description was introduced in 4.15-rc1
with a mismatch in the graph remote endpoints, which would likely
result in the driver misinterpreting how the individual components fit
together.

mvebu fixess for 4.15 (part 1)
2 device tree related fixes fixing 2 issues:
- broken pinctrl support since 4.11 on OpenBlocks A7
- implicit clock dependency making the kernel hang if the Xenon sdhci
module was loaded before the mvpp2 Ethernet support (for this one
the driver had to be fixed which was done in v4.14)

To avoid configuration override, timestamp set call will
be moved from the netdevice open flow to the init flow.
By this, a close-open procedure will not override the timestamp
configuration.
In addition, the change will rename mlx5e_timestamp_set function
to be mlx5e_timestamp_init.

Set features function sets dev->features in order to keep track of which
features were successfully changed and which weren't (in case the user
asks for more than one change in a single command).
This breaks the logic in __netdev_update_features which assumes that
dev->features is not changed on success and checks for diffs between
features and dev->features (diffs that might not exist at this point
because of the driver override).
The solution is to keep track of successful/failed feature changes and
assign them to dev->features in case of failure only.

ethtool statistics should be updated even when the interface is down
since it shows more than just netdev counters, which might change while
the logical link is down.
One useful use case, for example, is when running RoCE traffic over the
interface (while the logical link is down, but physical link is up) and
examining rx_prioX_bytes.

mlx5_get_vector_affinity used to call pci_irq_get_affinity and after
reverting the patch that sets the device affinity via PCI_IRQ_AFFINITY
API, calling pci_irq_get_affinity becomes useless and it breaks RDMA
mlx5 users. To fix this, this patch provides an alternative way to
retrieve IRQ vector affinity using legacy IRQ API, following
smp_affinity read procfs implementation.
