tests/kernel/t_time_arith.c: update for the recent kernel change
the test updates in the recent change was for some reasons incomplete.
("itimer_transition: do not keep it_value unchanged after firing the event")
https://mail-index.netbsd.org/source-changes/2026/03/17/msg161046.html
this commit updates the rest of tests.
tested with a full build and then the following command:
```
# chroot destdir
# cd /usr/tests/kernel
# atf-run t_time_arith > /dev/null
# echo $?
0
#
```
test failures are pointed out by Taylor R Campbell

ahc: Fix support for multi-channel PCI controllers.
Some old EISA controllers driven by ahc had two channels on one
controller (aka "TWIN" channels), while all later PCI models
supporting multiple channels did so by having multiple controllers
in one PCI device, each being a separate PCI function.
The ahc interrupt handler wrongly assumed that anything but channel
'A' is always the 2nd channel of a TWIN channel controller, passing
sc_channel_b to scsipi_channel_{freeze,thaw}(). This of course is
wrong for multi-channel PCI ahc controllers, leading to a immediate
panic when there's anything connected to any channel but 'A'.
Some platforms need to declare the vector table in a particular way
for their own reasons. mac68k falls into this category; it needs
be at address $0000.0000 and immediately preceed the Mac ROM variable
storage area.
Provide a hook for this to allow such platforms to use the shared
vector table initialization and manipulation routines.
Oops missed sun3x in previous changes:
Now that all of the m68k copies of the "rei" function are functionally
equivalent, pick the one that uses the fewest cycles in the "no AST
pending" case and re-factor it into trap_subr.s.
Re-factor badtrap into the shared trap_subr.s. This time we pick the
sun2/sun3 implementation of this trap stub because it provides more
context to the stray trap reporting routine (adjust the N copies of
straytrap() to compensate as needed, sigh).
Re-factor trap0 (system calls) into trap_subr.s. Here we pick the flavor
that has the in-line astpending check bcause it's a few cycles faster in
the (common) case where no AST is pending at the end of a system call.
Re-factor trap12 ("cachectl") into trap_subr.s. Already identical everywhere
except for 68010, where it's a no-op.
PR/59994 gcc/m68k generates bad code for stack protector
Record the alignment of the stack canary before allocating space for
it in a stack frame.
Generate an assignment expression to initialise the canary instead of
emitting a move instruction.
vax __lwp_getprivate_fast: Fix asm constraints.
r0 is not clobbered; it is the output. So say so.
No volatile is needed here, and volatile would be wrong, because
calls to __lwp_getprivate_fast can be safely deleted if the result is
not used.
