The documentation didn't actually mention how to enable no_new_privs.
This also adds a note about possible interactions between
no_new_privs and LSMs (i.e. why teaching systemd to set no_new_privs
is not necessarily a good idea), and it references the new docs

This patch drops the _ACTIVE part from the selection target names
as a prerequisite to unify the selection target names across the subdev

The meaning of V4L2_SEL_TGT_*_ACTIVE and V4L2_SUBDEV_SEL_TGT_*_ACTUAL
selection targets is logically the same. Different names add to confusion
where both APIs are used in a single driver or an application. For some
system configurations different names may lead to interoperability issues.
For backwards compatibility V4L2_SEL_TGT_CROP_ACTIVE and
V4L2_SEL_TGT_COMPOSE_ACTIVE are defined as aliases to V4L2_SEL_TGT_CROP

There are a few (new) usbdevfs capabilities which an application cannot
discover in any other way then checking the kernel version. There are 3
problems with this:
1) It is just not very pretty.
2) Given the tendency of enterprise distros to backport stuff it is not
reliable.
3) As discussed in length on the mailinglist, USBDEVFS_URB_BULK_CONTINUATION
does not work as it should when combined with USBDEVFS_URB_SHORT_NOT_OK
(which is its intended use) on devices attached to an XHCI controller.
So the availability of these features can be host controller dependent,
making depending on them based on the kernel version not a good idea.
This patch besides adding the new ioctl also adds flags for the following
existing capabilities:
USBDEVFS_CAP_ZERO_PACKET, available since 2.6.31
USBDEVFS_CAP_BULK_CONTINUATION, available since 2.6.32, except for XHCI
USBDEVFS_CAP_NO_PACKET_SIZE_LIM, available since 3.3
Note that this patch only does not advertise the USBDEVFS_URB_BULK_CONTINUATION
cap for XHCI controllers, bulk transfers with this flag set will still be
accepted when submitted to XHCI controllers.
Returning -EINVAL for them would break existing apps, and in most cases the
troublesome scenario wrt USBDEVFS_URB_SHORT_NOT_OK urbs on XHCI controllers
will never get hit, so this would break working use cases.
The disadvantage of not returning -EINVAL is that cases were it is causing
real trouble may go undetected / the cause of the trouble may be unclear,
but this is the best we can do.

Remove rproc_get_by_name() and rproc_put(), and the associated
remoteproc infrastructure that supports it (i.e. klist and friends),
because:
1. No one uses them
2. Using them is highly discouraged, and any potential user
will be deeply scrutinized and encouraged to move.
If a user, that absolutely can't live with the direct boot/shutdown
model, does show up one day, then bringing this functionality back
is going to be trivial.
At this point though, keeping this functionality around is way too
much of a maintenance burden.

For each registered rproc, maintain a generic remoteproc device whose
parent is the low level platform-specific device (commonly a pdev, but
it may certainly be any other type of device too).
With this in hand, the resulting device hierarchy might then look like:
omap-rproc.0
|
- remoteproc0 <---- new !
|
- virtio0
|
- virtio1
|
- rpmsg0
|
- rpmsg1
|
- rpmsg2
Where:
- omap-rproc.0 is the low level device that's bound to the
driver which invokes rproc_register()
- remoteproc0 is the result of this patch, and will be added by the
remoteproc framework when rproc_register() is invoked
- virtio0 and virtio1 are vdevs that are registered by remoteproc
when it realizes that they are supported by the firmware
of the physical remote processor represented by omap-rproc.0
- rpmsg0, rpmsg1 and rpmsg2 are rpmsg devices that represent rpmsg
channels, and are registerd by the rpmsg bus when it gets notified
about their existence
Technically, this patch:
- changes 'struct rproc' to contain this generic remoteproc.x device
- creates a new "remoteproc" type, to which this new generic remoteproc.x
device belong to.
- adds a super simple enumeration method for the indices of the
remoteproc.x devices
- updates all dev_* messaging to use the generic remoteproc.x device
instead of the low level platform-specific device
- updates all dma_* allocations to use the parent of remoteproc.x (where
the platform-specific memory pools, most commonly CMA, are to be found)
Adding this generic device has several merits:
- we can now add remoteproc runtime PM support simply by hooking onto the
new "remoteproc" type
- all remoteproc log messages will now carry a common name prefix
instead of having a platform-specific one
- having a device as part of the rproc struct makes it possible to simplify
refcounting (see subsequent patch)
Thanks to Stephen Boyd <sboyd@codeaurora.org> for suggesting and
discussing these ideas in one of the remoteproc review threads and
to Fernando Guzman Lugo <fernando.lugo@ti.com> for trying them out
with the (upcoming) runtime PM support for remoteproc.
