Document "renesas,can-r8a7743" and "renesas,can-r8a7745" compatible
strings. Since the fallback compatible string ("renesas,rcar-gen2-can")
activates the right code in the driver, no driver change is needed.

is named kpktgend_<cpu>, rather than pktgen/<cpu>.
o Use pg_ctrl for start/stop as it can work well with pgset without
changes to $(PGDEV) variable.
o Clarify a bit needed $(PGDEV) definition for sample scripts and that
one needs to `source functions.sh`.
o Document how-to unset a behaviour flag, note about history expansion.

Introduce the "nfs_export" config, module and mount options.
The NFS export feature depends on the "index" feature and enables two
implicit overlayfs features: "index_all" and "verify_lower".
The "index_all" feature creates an index on copy up of every file and
directory. The "verify_lower" feature uses the full index to detect
overlay filesystems inconsistencies on lookup, like redirect from
multiple upper dirs to the same lower dir.
NFS export can be enabled for non-upper mount with no index. However,
because lower layer redirects cannot be verified with the index, enabling
NFS export support on an overlay with no upper layer requires turning off
redirect follow (e.g. "redirect_dir=nofollow").
The full index may incur some overhead on mount time, especially when
verifying that lower directory file handles are not stale.
NFS export support, full index and consistency verification will be
implemented by following patches.

Mention the maximum voltages of the CEC and HPD lines. Since in the example
these lines are connected to a Raspberry Pi and the Rpi GPIO lines are 3.3V
it is a good idea to warn against directly connecting the HPD to the Raspberry

Since commit 9b6192589be7 ("media: lirc: implement scancode sending"),
and commit de142c324106 ("media: lirc: implement reading scancode")
the lirc features ioctl for raw IR devices advertises two modes for
sending and receiving.
The lirc daemon now fails to detect a raw IR device, both for transmit
and receive.
To fix this, do not advertise the scancode mode in the lirc features
for raw IR devices (however do keep it for scancode devices). The mode
can still be used via the LIRC_SET_{REC,SEND}_MODE ioctl.

DAX is a coprocessor which resides on the SPARC M7 (DAX1) and M8
(DAX2) processor chips, and has direct access to the CPU's L3 caches
as well as physical memory. It can perform several operations on data
streams with various input and output formats. This driver provides a
transport mechanism and has limited knowledge of the various opcodes
and data formats. A user space library provides high level services
and translates these into low level commands which are then passed
into the driver and subsequently the hypervisor and the coprocessor.
The library is the recommended way for applications to use the
coprocessor, and the driver interface is not intended for general use.

Now that we have the dts clocks for the clkctrl clock and the

users according to the binding to make it usable for drivers.
Apologies for not being able to send this earlier but it took
me few revisions to get the smartreflex changes right and
tested with yet to be posted patches to make smartreflex probe

sure we're not introducing regressions for legacy platform data
based booting.
Note that this is based on a merge with commit 20a2742e5784

This adds a new ioctl, KVM_PPC_GET_CPU_CHAR, that gives userspace
information about the underlying machine's level of vulnerability
to the recently announced vulnerabilities CVE-2017-5715,
CVE-2017-5753 and CVE-2017-5754, and whether the machine provides
instructions to assist software to work around the vulnerabilities.
The ioctl returns two u64 words describing characteristics of the
CPU and required software behaviour respectively, plus two mask
words which indicate which bits have been filled in by the kernel,
for extensibility. The bit definitions are the same as for the
new H_GET_CPU_CHARACTERISTICS hypercall.
There is also a new capability, KVM_CAP_PPC_GET_CPU_CHAR, which
indicates whether the new ioctl is available.
