When SMP support for powerpc was added in r178628, the last callers of this
function were removed. All code that needs to manipulate the task priority
just does it directly instead.

The KERN_TLS only supports TCP, so use of the "tls" option with "udp" will
not work. This patch adds a test for this case, so that the mount is not
attempted when both "tls" and "udp" are specified.
These devices have non-pccard attachments. Warn for those as well. Both an and

an needs firmware from Cisco, which I don't think was ever produced. wi could
in theory do it with raw frames and on-host encryption, but nobody has written
that in the 15 years since WEP was cracked.

Noted in D24652, we currently set shmfd->shm_flags on every
shm_open()/shm_open2(). This wasn't properly thought out; one shouldn't be
able to specify incompatible flags on subsequent opens of non-anon shm.
Move setting of shm_flags explicitly to the two places shmfd are created, as
we do with seals, and validate when we're opening a pre-existing mapping
that we've either passed no flags or we've passed the exact same flags as
the first time.

When the zone_jumbop is exhausted, most things using
using sosend* (like sshd) will eventually
fail or hang if allocations are limited to the
depleted jumbop zone. This makes it imossible to
communicate with a box which is under an attach which
exhausts the jumbop zone.
Rather than depending on the page size zone, also try cluster
allocations to satisfy larger requests. This allows me
to ssh to, and serve 100Gb/s of traffic from a server which
under attack and has had its page-sized zone exhausted.

To paraphrase the below-referenced PR:
This logic originated in the KAME project, and was even controversial when
it was enabled there by default in 2001. No such equivalent logic exists in
the IPv4 stack, and it turns out that this leads to us dropping valid
traffic when the "point to point" interface is actually a 1:many tun
interface, e.g. with the wireguard userland stack.
Even in the case of true point-to-point links, this logic only avoids
transient looping of packets sent by misconfigured applications or
attackers, which can be subverted by proper route configuration rather than
hardcoded logic in the kernel to drop packets.
In the review, melifaro goes on to note that the kernel can't fix it, so it
perhaps shouldn't try to be 'smart' about it. Additionally, that TTL will
still kick in even with incorrect route configuration.
