On recent OpenBMC firmware, the onboard ASMEDIA video card framebuffer
address was removed from device tree for security purposes (value is set
to zero to avoid leaking the address).
This patch works around the problem by taking framebuffer base address
from the "ranges" property of a parent node.

- Use Cm instead of Ar or Sq for command modifiers of the -v flag.
- Remove unnecessary "Ar ..." from the synopsis. It's not clear what it
was referring to.
- Add missing arguments to the -f and -v flags.
- Stylize the dot before "ss" with Cm in the default format in the -f
flag description.
- Set LC_ALL=C in the last example so that the output format of
date(1) always matches the specified format of the -f flag not matter
the locale.

Revision 9e9be081d8 introduced a new devfs rule devfsrules_jail_vnet. It
includes rule devfsrules_jail which include other rules. Unfortunately
devfs could not recursively parse the action include and thus
devfsrules_jail_vnet will expose all nodes.

The existing logic didn't take into account newly inserted mappings
wholly contained by an existing region (or vice versa), nor did it
account for weird overlap scenarios. The latter is probably unlikely
to happen, but the former may happen in UEFI: BootServicesData allocated
within a large chunk of ConventionalMemory. This situation blows up vm
initialization.
While we're here, remove the "exact match" logic as it's likely wrong;
if an exact match exists with conflicting flags, for instance, then we
should probably be doing something else. The new logic takes into
account exact matches as part of the overlapping efforts.

The nfscl_getref() function is called within nfscl_doiods() when
the NFSv4.1/4.2 pNFS client is doing I/O on a DS. As such,
nfscl_getref() needs to check for a forced dismount.
This patch adds that check.

As mention previously, the minmax polynomial approximation
in the kernel for cosl() seem to have a bad set of coefficients.
In testing, cosl() in the interval [0.785, pi/4] for 1 million
values and pi/4 written to 37 decimal digits. The old version
on an aarch64 system gave
% tlibm/tlibm_lmath -l -x 0.78 -X

The max ULP exceeds 1, which is not good. So, I rinsed off a 10

For NFS RPCs that receive a NFSERR_DELAY reply, the delay time
is initially 1sec and then increases exponentially to NFS_TRYLATERDEL.
It was found that this delay time is excessive for some NFSv4
servers, which work well with a 1msec delay.
A 1sec delay resulted in very slow performance for Remove and
Rename when delegations and pNFS were enabled.
This patch decreases the initial delay time to 1msec.
