Maybe .Fx provides?

of <remove the> processes owned by a different uid

"sysctl's" is a possessive here; since there's only one sysctl in question the apostrophe should go before the final 's'.

969 ↗(On Diff #60338)

Maybe "only allows unprivileged users to send"?

985 ↗(On Diff #60338)

"so-called" is hyphenated.
I'd consider wrapping Meltdown in .Dq as well, but that's less clear.

987 ↗(On Diff #60338)

"By default, the system detects whether the CPU needs the workaround".

1002 ↗(On Diff #60338)

spurious space here.

1007 ↗(On Diff #60338)

Maybe, "which report errors other than"

1022 ↗(On Diff #60338)

I think the grammar is better as "on NMI; this provides"

1042 ↗(On Diff #60338)

"a non-zero value"

1043 ↗(On Diff #60338)

"the end of the aux vector"

1045 ↗(On Diff #60338)

comma both before and after "i.e.".
