Various pages: Standardize wording around setting of 'errno' on error
...
In the RETURN VALUE sections, a number of different wordings
are used in to describe the fact that 'errno' is set on error.
There's no reason for the difference in wordings, since the same
thing is being described in each case. Switch to a standard
wording that is the same as FreeBSD and similar to the wording
used in POSIX.1.
In this change, fix some instances stating that 'errno' is set
"appropriately" to instead say "to indicate the error".

man2/*: srcfix: fix warnings from "mandoc -Tlint"
...
Remove superfluous paragraph macros.
Remove ".br" if it is before a line that starts with a space
character, as such lines automatically cause a break.
###
The output is unchanged, except two empty lines are added at the
bottom (before the footer line) in the output of "nroff" for the files
"alloc_hugepages.2" and "userfaultfd.2".
###
Examples of warnings from "mandoc -Tlint":
mandoc: access.2:283:2: WARNING: skipping paragraph macro: PP after SH
mandoc: adjtimex.2:185:2: WARNING: skipping paragraph macro: PP empty
mandoc: futex.2:728:2: WARNING: skipping paragraph macro: IP empty

prctl.2: Clarify the unsupported hardware case of EINVAL
...
prctls that are architecture-specific won't work on other
architectures, and arch-specific prctls that manipulate optional
hardware features likewise won't work if that hardware feature is
not present.
The established pattern seems to be to treat such prctls as if they
are unimplemented, when attempted on the wrong hardware.
Cover these cases with some generic weasel words in the closet
existing EINVAL clause.

prctl.2: Work around bogus constant "maxsig" in PR_SET_PDEATHSIG
...
The description of PR_SET_PDEATHSIG refers to "maxsig", which
is apparently intended to stand for the maximum defined signal
number.
maxsig seems not to be a thing, even in the kernel.
Reword to use the standard constant NSIG. (Discussion of SIGRTMIN
and SIGRTMAX seems out of scope here, and anyway is not relevant
to the kernel.)

prctl.2: Sort prctls into alphabetical order
...
The prctl list has historically been sorted by prctl name (ignoring
any SET_ or GET_ prefix) to make individual prctls easier to find.
Some noise seems to have crept in since.
Sort the list back into order. Similarly, reorder the list of
prctls specified to return non-zero values on success.
Content movement only. No semantic change.

prctl.2: srcfix: add comments for navigation
...
The prctl.2 source is unnecessarily hard to navigate, not least
because prctl option flags are traditionally named PR_* and so look
just like prctl names.
For each actual prctl, add a comment of the form
.\" prctl PR_FOO
to make it move obvious where each top-level prctl starts.
Of course, we could add some clever macros, but let's not confuse
dumb parsers.

prctl.2: Add health warning
...
In reality, almost every prctl interferes with assumptions that the
compiler and C library / runtime rely on. prctl() can therefore
make userspace explode in a variety ways that are likely to be hard
to debug.
This is not obvious to the uninitiated, so add a warning.

prctl.2: Clarify that prctl can apply to threads
...
The current synopsis for prctl(2) misleadingly claims that prctl
operates on a process. Rather, some (in fact, most) prctls operate
on a thread.
The wording probably dates back to the old days when Linux didn't
really have threads at all.
Reword as appropriate.
