This reverts commit 59eab1093a.
The change suppressed EFAULT originating from uiomove(). The deadlock
avoidance mechanism implemented by vn_io_fault1() in the VFS handles
such errors by wiring the user pages and retrying, but this change
caused read() to return early instead. This can result in short I/O,
causing misbehaviour in some applications, and possibly other
consequences.
Until this is resolved somehow, revert the commit.

The last two drivers that required sppp are cp(4) and ce(4).
These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.
Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially. Later they have dropped
support for Linux drivers to. As of mid-2020 they don't even
have a developer to maintain their Windows driver. However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.
These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP. Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.
Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part. Further maintenance of these
drivers in the tree shouldn't be a big deal.
While doing that, remove some cruft and enable cp(4) compilation
on amd64. The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.

Correct input_sta "assertion" checks. CTS/ACK CTRL frames are shorter
then sizeof(struct ieee80211_frame_min) and were thus running into the
is_rx_tooshort error case.
Use ieee80211_anyhdrsize() to handle this better but make sure we do
at least have the first 2 octets needed for that.
While here move the safety checks before any code which may not obey
them later, just for good style.
The non-scanning check further down assumes a frame format also not
matching control frames. For now skip the checks for control frames
which allows us to deal with some of them at least now.

ping uses a two-pass option parser. The first pass determines whether
ipv4 or ipv6 is desired, and the second parses the rest of the options.
But the first pass wrongly detects a '4' or '6' in an option's value as
a request to use ipv6 or ipv6 respectively, for example in an invocation
like "ping -c6 1.2.3.4".
Fix this confusion by including all options in the first round of
parsing, but ignoring those unrelated to ipv4/ipv6 selection.

Previously in_pcbbind_setup returned EADDRNOTAVAIL for empty
V_in_ifaddrhead (i.e., no IPv4 addresses configured) and in6_pcbbind
did the same for empty V_in6_ifaddrhead (no IPv6 addresses).
An equivalent test has existed since 4.4-Lite. It was presumably done
to avoid extra work (assuming the address isn't going to be found
later).
In normal system operation *_ifaddrhead will not be empty: they will
at least have the loopback address(es). In practice no work will be
avoided.
Further, this case caused net/dhcpd to fail when run early in boot
before assignment of any addresses. It should be possible to bind the
unspecified address even if no addresses have been configured yet, so
just remove the tests.
The now-removed "XXX broken" comments were added in 59562606b9,

2. Even when working, the feature numbered the enclosure

if a port was down or didn't appear in sysfs, then the

Fix boot1 and loader on PowerPC64 little-endian (LE).
Due to endian issues, boot1 couldn't find the UFS boot partition
and loader wasn't able to load the kernel. Most of the issues
happened because boot1 and loader were BE binaries trying to access
LE UFS partitions and because loader expects the kernel ELF image
to use the same endian as itself.
To fix these issues, boot1 and loader are now built as LE binaries
on PPC64LE. To support this, the functions that call OpenFirmware
were enhanced to correctly perform endian conversion on its input
and output arguments and to change the CPU into BE mode before
making the calls, as OpenFirmware always runs in BE. Besides that,
some other small fixes were needed.
