This patch makes path_is_under return bool to improve
readability due to this particular function only using either
one or zero as its return value.
No functional change.

Currently when CONFIG_BLOCK is defined sb_is_blkdev_sb returns bool,
while when CONFIG_BLOCK is not defined it returns int. Let's keep
consistent to make sb_is_blkdev_sb return bool as well when CONFIG_BLOCK
isn't defined.
No functional change.

In the similar way like we do for the platform data we propagate the device
properties. For example, in case of Intel LPSS drivers we may provide a
specific property to tell the actual device driver an additional information
such as platform name.

Make it possible to pass built-in device properties to platform device
drivers. This is useful if the system does not have any firmware interface
like Device Tree or ACPI which provides these.
Properties associated with the platform device will be automatically
released when the corresponding device is removed.

It is convenient if the property set associated with the device secondary
firmware node is a copy of the original. This allows passing property set
from a stack for example for devices created dynamically. This also ties
the property set lifetime to the associated device.
Because of that we provide new function device_remove_property_set() that
is used to disassociate and release memory allocated for the property set.

The component helper treats the void match data pointer as an opaque
object which needs no further management. When device nodes being
passed, this is not true: the caller should pass its refcount to the
component helper, and there should be a way to drop the refcount when
the matching information is destroyed.
This patch provides a per-match release method in addition to the match
method to solve this issue. Rather than using component_match_add(),
users should use component_match_add_release() which takes an additional
function pointer for releasing this reference.

Now that drivers create an array of component matches at probe time, we
can retire the old methods. This involves removing the add_components
master method, and removing component_master_add_child() from public
view. We also remove component_add_master() as that interface is no
longer useful.

Steven recommended open coding access to tracepoint->key to add
trace points to headers. Unfortunately this is difficult for some
headers (such as x86 asm/msr.h) because including tracepoint.h
includes so many other headers that it causes include loops.
The main problem is the include of linux/rcupdate.h, which
pulls in a lot of other headers. The rcu header is only needed
when actually defining trace points.
Move the struct tracepoint into a separate tracepoint-defs.h
header that can be included without pulling in all of RCU.

Modules have three sections: text, rodata and writable data. The code
handled the case where these overlapped, however they never can:
debug_align() ensures they are always page-aligned.
This is why we got away with manually traversing the pages in
set_all_modules_text_rw() without rounding.
We create three helper functions: frob_text(), frob_rodata() and
frob_writable_data(). We then call these explicitly at every point,
so it's clear what we're doing.
We also expose module_enable_ro() and module_disable_ro() for
livepatch to use.

The list_splice_init_rcu() can be used as a stack onto which full lists

__list_splice_init_rcu() function. This new function is based on the
existing list_splice_init_rcu() implementation.

We need the scheduler's fastpaths to be, well, fast, and unnecessarily
disabling and re-enabling interrupts is not necessarily consistent with
this goal. Especially given that there are regions of the scheduler that
already have interrupts disabled.
This commit therefore moves the call to rcu_note_context_switch()
to one of the interrupts-disabled regions of the scheduler, and
removes the now-redundant disabling and re-enabling of interrupts from
rcu_note_context_switch() and the functions it calls.

Although expedited grace periods can be quite useful, and although their
OS jitter has been greatly reduced, they can still pose problems for
extreme real-time workloads. This commit therefore adds a rcu_normal
kernel boot parameter (which can also be manipulated via sysfs)
to suppress expedited grace periods, that is, to treat requests for
expedited grace periods as if they were requests for normal grace periods.
If both rcu_expedited and rcu_normal are specified, rcu_normal wins.
This means that if you are relying on expedited grace periods to speed up
boot, you will want to specify rcu_expedited on the kernel command line,
and then specify rcu_normal via sysfs once boot completes.

Thomas and Phil observed that under stress rhashtable insertion
sometimes failed with EBUSY, even though this error should only
ever been seen when we're under attack and our hash chain length
has grown to an unacceptable level, even after a rehash.
It turns out that the logic for detecting whether there is an
existing rehash is faulty. In particular, when two threads both
try to grow the same table at the same time, one of them may see
the newly grown table and thus erroneously conclude that it had
been rehashed. This is what leads to the EBUSY error.
This patch fixes this by remembering the current last table we
used during insertion so that rhashtable_insert_rehash can detect
when another thread has also done a resize/rehash. When this is
detected we will give up our resize/rehash and simply retry the
insertion with the new table.

Pull power management and ACPI fixes from Rafael Wysocki:
"These fix a recent regression in the ACPI PCI host bridge
initialization code, clean up some recent changes (generic power
domains framework, ACPI AML debugger support), fix three older but
annoying bugs (PCI power management. generic power domains framework,
cpufreq) and a build problem (device properties framework), and update
a stale MAINTAINERS entry (ACPI backlight driver).
Specifics:
- Fix a regression in the ACPI PCI host bridge initialization code
introduced by the recent consolidation of the host bridge handling
on x86 and ia64 that forgot to take one special piece of code
related to NUMA on x86 into account (Liu Jiang).
- Improve the Kconfig help description of the new ACPI AML debugger
support option to avoid possible confusion (Peter Zijlstra).
- Remove a piece of code in the generic power domains framework that
should have been removed by one of the recent commits modifying
that code (Ulf Hansson).
- Reduce the log level of a PCI PM message that generates a lot of
false-positive log noise for some drivers and improve the message
itself while at it (Imre Deak).
- Fix the OF-based domain lookup code in the generic power domains
framework to make it drop references to DT nodes correctly (Eric
Anholt).
- Prevent the cpufreq core from setting the policy back to the
default after a CPU offline/online cycle for cpufreq drivers
providing the ->setpolicy callback (Srinivas Pandruvada).
- Fix a build problem for CONFIG_ACPI unset in the device properties
framework (Hanjun Guo).
- Fix a stale file path in the ACPI backlight driver entry in
MAINTAINERS (Dan Carpenter)"

Readers need to know if vtime runs at all on some CPU somewhere, this
is a fast-path check to determine if we need to check further the need
to add up any tickless cputime delta.
This fast path check uses context tracking state because vtime is tied
to context tracking as of now. This check appears to be confusing though
so lets use a vtime function that deals with context tracking details
in vtime implementation instead.

Pull block fixes from Jens Axboe:
"A collection of fixes from this series. The most important here is a
regression fix for an issue that some folks would hit in blk-merge.c,
and the NVMe queue depth limit for the screwed up Apple "nvme"
controller.
In more detail, this pull request contains:
- a set of fixes for null_blk, including a fix for a few corner cases
where we could hang the device. From Arianna and Paolo.
- lightnvm:
- A build improvement from Keith.
- Update the qemu pci id detection from Matias.
- Error handling fixes for leaks and other little fixes from
Sudip and Wenwei.
- fix from Eric where BLKRRPART would not return EBUSY for whole
device mounts, only when partitions were mounted.
- fix from Jan Kara, where EOF O_DIRECT reads would return
negatively.
- remove check for rq_mergeable() when checking limits for cloned
requests. The check doesn't make any sense. It's assuming that
since NOMERGE is set on the request that we don't have to
recalculate limits since the request didn't change, but that's not
true if the request has been redirected. From Hannes.
- correctly get the bio front segment value set for single segment
bio's, fixing a BUG() in blk-merge. From Ming"

In cases of duplicate symbols, sympos will be used to disambiguate instead
of val. By default sympos will be 0, and patching will only succeed if
the symbol is unique. Specifying a positive value will ensure that
occurrence of the symbol in kallsyms for the patched object will be used
for patching if it is valid. For external relocations sympos is not
supported.
Remove klp_verify_callback, klp_verify_args and klp_verify_vmlinux_symbol
as they are no longer used.
From the klp_reloc structure remove val, as it can be refactored as a
local variable in klp_write_object_relocations.

Currently, patching objects with duplicate symbol names fail because the
creation of the sysfs function directory collides with the previous
attempt. Appending old_addr to the function name is problematic as it
reveals the address of the function being patch to a normal user. Using
the symbol's occurrence in kallsyms to postfix the function name in the
sysfs directory solves the issue of having consistent unique names and
ensuring that the address is not exposed to a normal user.
In addition, using the symbol position as the user's method to disambiguate
symbols instead of addr allows for disambiguating symbols in modules as
well for both function addresses and for relocs. This also simplifies much
of the code. Special handling for kASLR is no longer needed and can be
removed. The klp_find_verify_func_addr function can be replaced by
klp_find_object_symbol, and klp_verify_vmlinux_symbol and its callback can
be removed completely.
In cases of duplicate symbols, old_sympos will be used to disambiguate
instead of old_addr. By default old_sympos will be 0, and patching will
only succeed if the symbol is unique. Specifying a positive value will
ensure that occurrence of the symbol in kallsyms for the patched object
will be used for patching if it is valid.
In addition, make old_addr an internal structure field not to be specified
by the user. Finally, remove klp_find_verify_func_addr as it can be
replaced by klp_find_object_symbol directly.
Support for symbol position disambiguation for relocations is added in the
next patch in this series.

A software trigger associates an IIO device trigger with a software
interrupt source (e.g: timer, sysfs). This patch adds the generic
infrastructure for handling software triggers.
Software interrupts sources are kept in a iio_trigger_types_list and
registered separately when the associated kernel module is loaded.
Software triggers can be created directly from drivers or from user
space via configfs interface.
To sum up, this dynamically creates "triggers" group to be found under
/config/iio/triggers and offers the possibility of dynamically
creating trigger types groups. The first supported trigger type is
"hrtimer" found under /config/iio/triggers/hrtimer.

E-Switch vport context is unlike NIC vport context, managed by the
E-Switch manager or vport_group_manager and not by the NIC(VF) driver.
The E-Switch manager can access (read/modify) any of its vports
E-Switch context.
Currently E-Switch vport context includes only clietnt and server
vlan insertion and striping data (for later support of VST mode).

Enabling E-Switch SRIOV for nvfs+1 vports.
Create E-Switch FDB for L2 UC/MC mac steering between VFs/PF and
external vport (Uplink).
FDB contains forwarding rules such as:
UC MAC0 -> vport0(PF).
UC MAC1 -> vport1.
UC MAC2 -> vport2.
MC MACX -> vport0, vport2, Uplink.
MC MACY -> vport1, Uplink.
For unmatched traffic FDB has the following default rules:
Unmached Traffic (src vport != Uplink) -> Uplink.
Unmached Traffic (src vport == Uplink) -> vport0(PF).
FDB rules population:
Each NIC vport (VF) will notify E-Switch manager of its UC/MC vport
context changes via modify vport context command, which will be
translated to an event that will be handled by E-Switch manager (PF)
which will update FDB table accordingly.
