If you change the set of filesystems that are exported, then
the contents of various directories in the NFSv4 pseudo-root
is likely to change. However the change-id of those
directories is currently tied to the underlying directory,
so the client may not see the changes in a timely fashion.
This patch changes the change-id number to be derived from the
"flush_time" of the export cache. Whenever any changes are
made to the set of exported filesystems, this flush_time is
updated. The result is that clients see changes to the set
of exported filesystems much more quickly, often immediately.

Vivien Didelot says:
====================
net: dsa: add fabric notifier
When a switch fabric is composed of multiple switch chips, these chips
must be programmed accordingly when an event occurred on one of them.
Examples of such event include hardware bridging: when a Linux bridge
spans interconnected chips, they must be programmed to allow external
ports to ingress frames on their internal ports.
Another example is cross-chip hardware VLANs. Switch chips in-between
interconnected bridge ports must also configure a given VLAN to allow
packets to pass through them.
In order to support that, this patchset introduces a non-intrusive
notifier mechanism. It adds a notifier head in every DSA switch tree
(the said fabric), and a notifier block in every DSA switch chip.
When an even occurs, it is chained to all notifiers of the fabric.
Switch chips can react accordingly if they are cross-chip capable.
On a dynamic debug enabled system, bridging a port in a multi-chip
fabric will print something like this (ZII Rev B board):
# brctl addif br0 lan3
mv88e6085 0.1:00: crosschip DSA port 1.0 bridged to br0
mv88e6085 0.4:00: crosschip DSA port 1.0 bridged to br0
# brctl delif br0 lan3
mv88e6085 0.1:00: crosschip DSA port 1.0 unbridged from br0
mv88e6085 0.4:00: crosschip DSA port 1.0 unbridged from br0
Currently only bridging events are added. A patchset introducing support
for cross-chip hardware bridging configuration in mv88e6xxx will follow
right after. Then events for switchdev operations are next on the line.
We should note that non-switchdev events do not support rolling-back
switch-wide operations. We'll have to work on closer integration with
switchdev for that, like introducing new attributes or objects, to
benefit from the prepare and commit phases.

In commit 86aa7e760a ("drm/i915: Assert that the context-switch
completion matches our context") I added a read to the irq tasklet
handler that compared the on-chip status with that of our sw tracking,
using an unguarded read of the request pointer to get the context and
beyond. Whilst we hold a reference to the request, we do not hold
anything on the context and if we are unlucky it may be reaped from a
second thread retiring the request (since it may retire the request as
soon as the breadcrumb is complete, even before we finish processing the
context switch) as we try to read from the context pointer.
Avoid the racy read from underneath the request by storing the expected
result in the execlist_port[].
v2: Include commentary about port[].request being unprotected.

Commit 618f535a60 ("ACPI/IORT: Add single mapping function")
introduced a function (iort_node_get_id()) to retrieve ids for IORT
named components.
The iort_node_get_id() takes an index as input to refer to a specific
mapping entry in the named component IORT node mapping array.
For a mapping entry at a given index, iort_node_get_id() should return
the id value (through the id_out function parameter) and the IORT node
output_reference (through function return value) the given mapping entry
refers to.
Technically output_reference values may differ for different map
entries, (see diagram below - mapped id values may refer to different eg
IORT SMMU nodes; the kernel may not be able to handle different
output_reference values for a given named component but the IORT kernel
layer should still report the IORT mappings as reported by firmware) but
current code in iort_node_get_id() fails to use the index function
parameter to return the correct output_reference value (ie it always
returns the output_reference value of the first entry in the mapping
array whilst using the index correctly to retrieve the id value from the
respective entry).
|----------------------|
| named component |
|----------------------|
| map entry[0] |
|----------------------|
| id value |
| output_reference----------------> eg SMMU 1
|----------------------|
| map entry[1] |
|----------------------|
| id value |
| output_reference----------------> eg SMMU 2
|----------------------|
.
.
.
|----------------------|
| map entry[N] |
|----------------------|
| id value |
| output_reference----------------> eg SMMU 1
|----------------------|
Consequently the iort_node_get_id() function always returns the IORT
node pointed at by the output_reference value of the first named
component mapping array entry, irrespective of the index parameter,
which is a bug.
Update the map array entry pointer computation in iort_node_get_id() to
take into account the index value, fixing the issue.

The NUMA code may get confused by the presence of NOMAP regions within
zones, resulting in spurious BUG() checks where the node id deviates
from the containing zone's node id.
Since the kernel has no business reasoning about node ids of pages it
does not own in the first place, enable CONFIG_HOLES_IN_ZONE to ensure
that such pages are disregarded.

Move the document describing PM notifiers (used during system sleep
state transitions) to Documentation/driver-api/pm/, convert it to reST
and update it to use current terminology. Also replace the remaining
references to the old version of it in .txt documents with references
to the new one.

The new document still contains references to some documents in the

Refresh the struct dev_pm_ops kerneldoc comment, so that it looks
better and is more readable after processing by Sphinx, and drop
the kerneldoc marker from a few other comments ("PM_EVENT_ messages"
and a couple of enum types declarations) which are not proper
kerneldoc and generally confuse Sphinx.
Also change the comment describing struct dev_pm_domain into
a kerneldoc one.

A typical SMP system expects cache coherency. Initial NPS platform
support was slated to be SMP w/o cache coherency.
However it seems the platform now selects that option, so there is no
point in keeping it around.

No need for specifying a list of interrupts in the declaration
of IDU interrupt controller anymore since the kernel can obtain
a number of supported interrupts from the build register.
Also delete support of the second parameter for devices which
are connected to IDU because it is not used anywhere.
