PR/60655: vmt(4) probes the VMware backdoor unconditionally on aarch64
On ACPI systems only probe for vmt(4) when Hypervisor_Id in FADT reports
VMWare.
This helps avoid buggy hypervisors that don't implement a RAZ mdccsr_el0
Patch from Showta Ishizaki and slightly updated by me.
col(1): reword -h description
Negation is harder to read. And it was not immediately clear if the
terse "(default)" remark relates to the whole sentence (i.e. -h is the
default) or only to the negated part ("do not do the default $thing").
(It was not too bad, but remember that the primary audience of the
manpages is a desperate sysadmin at 3am, so every tiny bit counts).
Import tzdata2026d (as with 2026c) from a locally generated gtz version
rather than from https://github.com/JodaOrg/global-tz/releases/download/2026dgtz/tzdata2026dgtz.tar.gz
Eventually tzdata updates will no longer appear just a day or two
(or longer in the European vacation season) before a NetBSD release
is planned (11 for 2026c, 10.2 for this one) and this local generation
of a gtz version of the data will not be needed.
As with the 2026c update when the real gtz file appears, if there are
any material differences, an update will be made (2026c needed nothing).
Summary of changes in tzdata2026d (2026-09-11 15:21:07 -0700):
* Canada’s Northwest Territories will not fall back on 2026-11-01
and will stay on -06 year-round, matching Alberta’s recent change.
* Colombia’s 1992-05-02 spring forward was at 00:00, not 24:00.
* Iran’s 1979-05-26 spring forward was at 00:00, not 24:00.
* The backward-compatibility names EST5EDT, CST6CDT, MST7MDT, and
PST8PDT now conform better to POSIX.
* The temporary hacks used for North American timekeeping changes

Fix a brain-o in a KASSERT that could cause a guest to panic a DIAGNOSTIC
kernel: to assert that an I/O is already in flight we want
xbdi_pendingreqs > 0, not xbdi_pendingreqs > 1
While there, fix an error path that could also cause a KASSERT to fire
or a state corruption: reset xio_need_bounce to 0 before calling
xbdback_io_error() when the bounce buffer is not fully set up.

t_mbrtowc: Mark UTF-8 test cases xfail.
mbrtowc previously failed to reject invalid (legacy 5/6-byte) UTF-8,
so it accepted this test case. Now it rejects this test case,
because the test case itself is broken.
Need to split this test up into:
1. correctly decoding the valid inputs
2. correctly rejecting the invalid inputs
But for now marking the test case xfail is an adequate approximation

Fix behaviour of rt_sigqueueinfo() when a thread group id (tgid) of -1 is
given. Previously this was passed as a process id to kill() which broadcasts
the signal (meanly you can accidentally kill all processes!).

Regen with makesyscalls.sh 1.188 as it changes the text of the "DO NOT EDIT"
comments in the generated files.
No intended functional change, but minimises diffs on future regens.
PR bin/60706 : sh(1) man page wording improvements.
Better describe how var-assign prefix words are processed.
A few other random cleanups in the nearby area.
No Dd update, these are not significant enough changes to suggest
to anyone that re-reading the man page would be worth the effort.
No pullups planned (same reason).
