int type range)

just built and booted from HEAD/20261002154359Z and during bootup there
is one remaining UBSan complaint about integer shifting on the EdgeRouter4:
[ 1.000000] UBSan: Undefined Behavior in /usr/build/HEAD_20261002154359Z/usr/src/sys/lib/libkern/../../../common/lib/libc/string/memset2.c:104:15, left shift of 4294967295 by 32 places cannot be represented in type 'long int'
(The kern_ntptime.c complaint is also still there, but that's because the
snapshot I used predates the patch for it, so I'm ignoring that one.)
