The truncation isn't being programmed if the truncation
depth is set to 2, it causes an issue with dce11.2 asic
using 6bit eDP panel. It required to truncate 12:10 in order to
perform spatial dither 10:6.
This change will allow 12:10 truncation to be enabled.

Add a device tree property description for hdmi device node
. '#sound-dai-cells' property is required to describe link between
the HDMI IP block and the SoC's audio subsystem and Exynos SoC device
tree files already have this property but we missed its description.

drm/tegra: Fixes for v4.16-rc7
This contains two small fixes for the alpha blending support that was
merged into v4.16-rc1 and a fix for connector reference leaks caused by
the fact that display pipelines are no longer automatically disabled if
the framebuffer is removed.
Furthermore this contains a fix for a crash on IOMMU detach at driver
unbind time and a regulator enable/disable unbalance fix.

Android's netd was basically pinning the uid cookie BPF map in BPF
fs (/sys/fs/bpf/traffic_cookie_uid_map) and later on retrieving it
again resulting in above panic. Issue is that the map was wrongly
identified as a prog! Above kernel was compiled with clang 4.0,
and it turns out that clang decided to merge the bpf_prog_iops and
bpf_map_iops into a single memory location, such that the two i_ops
could then not be distinguished anymore.
Reason for this miscompilation is that clang has the more aggressive
-fmerge-all-constants enabled by default. In fact, clang source code
has a comment about it in lib/AST/ExprConstant.cpp on why it is okay
to do so:
Pointers with different bases cannot represent the same object.
(Note that clang defaults to -fmerge-all-constants, which can
lead to inconsistent results for comparisons involving the address
of a constant; this generally doesn't matter in practice.)
The issue never appeared with gcc however, since gcc does not enable
-fmerge-all-constants by default and even *explicitly* states in
it's option description that using this flag results in non-conforming
behavior, quote from man gcc:
Languages like C or C++ require each variable, including multiple
instances of the same variable in recursive calls, to have distinct
locations, so using this option results in non-conforming behavior.
There are also various clang bug reports open on that matter [1],
where clang developers acknowledge the non-conforming behavior,
and refer to disabling it with -fno-merge-all-constants. But even
if this gets fixed in clang today, there are already users out there
that triggered this. Thus, fix this issue by explicitly adding
-fno-merge-all-constants to the kernel's Makefile to generically
disable this optimization, since potentially other places in the
kernel could subtly break as well.
Note, there is also a flag called -fmerge-constants (not supported
by clang), which is more conservative and only applies to strings
and it's enabled in gcc's -O/-O2/-O3/-Os optimization levels. In
gcc's code, the two flags -fmerge-{all-,}constants share the same
variable internally, so when disabling it via -fno-merge-all-constants,
then we really don't merge any const data (e.g. strings), and text
size increases with gcc (14,927,214 -> 14,942,646 for vmlinux.o).
$ gcc -fverbose-asm -O2 foo.c -S -o foo.S
-> foo.S lists -fmerge-constants under options enabled
$ gcc -fverbose-asm -O2 -fno-merge-all-constants foo.c -S -o foo.S
-> foo.S doesn't list -fmerge-constants under options enabled
$ gcc -fverbose-asm -O2 -fno-merge-all-constants -fmerge-constants foo.c -S -o foo.S
-> foo.S lists -fmerge-constants under options enabled
Thus, as a workaround we need to set both -fno-merge-all-constants
*and* -fmerge-constants in the Makefile in order for text size to
stay as is.

The current check statement in BPF syscall will do a capability check
for CAP_SYS_ADMIN before checking sysctl_unprivileged_bpf_disabled. This
code path will trigger unnecessary security hooks on capability checking
and cause false alarms on unprivileged process trying to get CAP_SYS_ADMIN
access. This can be resolved by simply switch the order of the statement
and CAP_SYS_ADMIN is not required anyway if unprivileged bpf syscall is
allowed.

Commit 4bebdc7a85aa ("bpf: add helper bpf_perf_prog_read_value")
added helper bpf_perf_prog_read_value so that perf_event type program
can read event counter and enabled/running time.
This commit, however, introduced a bug which allows this helper
for tracepoint type programs. This is incorrect as bpf_perf_prog_read_value
needs to access perf_event through its bpf_perf_event_data_kern type context,
which is not available for tracepoint type program.
This patch fixed the issue by separating bpf_func_proto between tracepoint
and perf_event type programs and removed bpf_perf_prog_read_value
from tracepoint func prototype.

Function bpf_fill_maxinsns11 is designed to not be able to be JITed on
x86_64. So, it fails when CONFIG_BPF_JIT_ALWAYS_ON=y, and
commit 09584b406742 ("bpf: fix selftests/bpf test_kmod.sh failure when
CONFIG_BPF_JIT_ALWAYS_ON=y") makes sure that failure is detected on that
case.
However, it does not fail on other architectures, which have a different
JIT compiler design. So, test_bpf has started to fail to load on those.
After this fix, test_bpf loads fine on both x86_64 and ppc64el.

The undocumented 'icebp' instruction (aka 'int1') works pretty much like
'int3' in the absense of in-circuit probing equipment (except,
obviously, that it raises #DB instead of raising #BP), and is used by
some validation test-suites as such.
But Andy Lutomirski noticed that his test suite acted differently in kvm
than on bare hardware.
The reason is that kvm used an inexact test for the icebp instruction:
it just assumed that an all-zero VM exit qualification value meant that
the VM exit was due to icebp.
That is not unlike the guess that do_debug() does for the actual
exception handling case, but it's purely a heuristic, not an absolute
rule. do_debug() does it because it wants to ascribe _some_ reasons to
the #DB that happened, and an empty %dr6 value means that 'icebp' is the
most likely casue and we have no better information.
But kvm can just do it right, because unlike the do_debug() case, kvm
actually sees the real reason for the #DB in the VM-exit interruption
information field.
So instead of relying on an inexact heuristic, just use the actual VM
exit information that says "it was 'icebp'".
Right now the 'icebp' instruction isn't technically documented by Intel,
but that will hopefully change. The special "privileged software
exception" information _is_ actually mentioned in the Intel SDM, even
though the cause of it isn't enumerated.

Prior to access UCMA commands, the context should be initialized
and connected to CM_ID with ucma_create_id(). In case user skips
this step, he can provide non-valid ctx without CM_ID and cause
to multiple NULL dereferences.
Also there are situations where the create_id can be raced with
other user access, ensure that the context is only shared to
other threads once it is fully initialized to avoid the races.

Scheduler debug stats include newlines that display out of alignment

% dmesg
...

runnable tasks:

At the same time, some syslog utilities (like rsyslog by default) don't

When the SEQ_printf() macro prints to the console, it runs a simple
printk() without KERN_CONT "continued" line printing. The result of
this is oddly wrapped task info, for example:

When a perf_event is attached to parent cgroup, it should count events
for all children cgroups:
parent_group <---- perf_event
\
- child_group <---- process(es)
However, in our tests, we found this perf_event cannot report reliable
results. Here is an example case:
# create cgroups
mkdir -p /sys/fs/cgroup/p/c
# start perf for parent group
perf stat -e instructions -G "p"
# on another console, run test process in child cgroup:
stressapptest -s 2 -M 1000 & echo $! > /sys/fs/cgroup/p/c/cgroup.procs
# after the test process is done, stop perf in the first console shows
<not counted> instructions p
The instruction should not be "not counted" as the process runs in the
child cgroup.
We found this is because perf_event->cgrp and cpuctx->cgrp are not
identical, thus perf_event->cgrp are not updated properly.
This patch fixes this by updating perf_cgroup properly for ancestor
cgroup(s).

servers
The number of CHAs is miscalculated on multi-domain PCI Skylake server systems,
resulting in an uncore driver initialization error.
Gary Kroening explains:
"For systems with a single PCI segment, it is sufficient to look for the
bus number to change in order to determine that all of the CHa's have
been counted for a single socket.
However, for multi PCI segment systems, each socket is given a new
segment and the bus number does NOT change. So looking only for the
bus number to change ends up counting all of the CHa's on all sockets
in the system. This leads to writing CPU MSRs beyond a valid range and
causes an error in ivbep_uncore_msr_init_box()."
To fix this bug, query the number of CHAs from the CAPID6 register:
it should read bits 27:0 in the CAPID6 register located at
Device 30, Function 3, Offset 0x9C. These 28 bits form a bit vector
of available LLC slices and the CHAs that manage those slices.

With the following commit:
333522447063 ("jump_label: Explicitly disable jump labels in __init code")
... we explicitly disabled jump labels in __init code, so they could be
detected and not warned about in the following commit:
dc1dd184c2f0 ("jump_label: Warn on failed jump_label patching attempt")
In-kernel __exit code has the same issue. It's never used, so it's
freed along with the rest of initmem. But jump label entries in __exit
code aren't explicitly disabled, so we get the following warning when
enabling pr_debug() in __exit code:

WARNING: CPU: 0 PID: 22572 at kernel/jump_label.c:376 __jump_label_update+0x9d/0xb0

both __init and __exit code).

Userspace RDPMC cannot possibly work for large PEBS, which was introduced in:
b8241d20699e ("perf/x86/intel: Implement batched PEBS interrupt handling (large PEBS interrupt threshold)")
When the PEBS interrupt threshold is larger than one, there is no way
to get exact auto-reload times and value for userspace RDPMC. Disable
the userspace RDPMC usage when large PEBS is enabled.
The only exception is when the PEBS interrupt threshold is 1, in which
case user-space RDPMC works well even with auto-reload events.

Binutils 2.31 will enable -z separate-code by default for x86 to avoid
mixing code pages with data to improve cache performance as well as
security. To reduce x86-64 executable and shared object sizes, the
maximum page size is reduced from 2MB to 4KB. But x86-64 kernel must
be aligned to 2MB. Pass -z max-page-size=0x200000 to linker to force
2MB page size regardless of the default page size used by linker.

will try to create sysfs link netdev->phydev for second PHY
in phy_attach_direct(), because sysfs link with the same name has been
created already for the first PHY.
As result, second CPSW external port will became unusable.
This regression was introduced by commits:
5568363f0cb3 ("net: phy: Create sysfs reciprocal links for attached_dev/phydev"
a3995460491d ("net: phy: Relax error checking on sysfs_create_link()"
Patch 1: exports sysfs_create_link_nowarn() function as preparation for Patch 2.
Patch 2: relaxes error checking when PHYLIB framework is creating sysfs
link netdev->phydev in phy_attach_direct(), suppresses warning by using
sysfs_create_link_nowarn() and adds error message instead, so links creation
failure is not fatal any more and system can continue working,
which fixes TI CPSW issue and makes boot logs accessible
in case of NFS boot, for example.
This can be stable material 4.13+.
Changes in v2:
- commit messages updated.
v1:

Some ethernet drivers (like TI CPSW) may connect and manage >1 Net PHYs per
one netdevice, as result such drivers will produce warning during system
boot and fail to connect second phy to netdevice when PHYLIB framework
will try to create sysfs link netdev->phydev for second PHY
in phy_attach_direct(), because sysfs link with the same name has been
created already for the first PHY. As result, second CPSW external
port will became unusable.
Fix it by relaxing error checking when PHYLIB framework is creating sysfs
link netdev->phydev in phy_attach_direct(), suppressing warning by using
sysfs_create_link_nowarn() and adding error message instead.
After this change links (phy->netdev and netdev->phy) creation failure is not
fatal any more and system can continue working, which fixes TI CPSW issue.

The sysfs_create_link_nowarn() is going to be used in phylib framework in
subsequent patch which can be built as module. Hence, export
sysfs_create_link_nowarn() to avoid build errors.
