Description

Stop building and delivering the 32-bit kernel and related modules. This does include both kernel modules and mdb modules for 32-bit kernel, note we still have to provide 32-bit msb modules to be able to debug 32-bit userland.

FYI the 32-bit kernel stopped working a few months back. I forget which commit broke it (my guess would be #8376); it was something to do with the size of 'struct vnode'.

I don't think it's quite as simple as 8376.

Tribblix m20.1 has 8376, and boots in 32-bit mode, installs to UFS root, and runs fine. Using ZFS is a little problematic for 32-bit, so I tend to test with UFS anyway

The Tribblix m20.2 live media doesn't boot in 32-bit mode at all, svc.configd dies and nothing works.

That would put the brokenness between 04427e3bf236c18cc532680b957267ee70b1037d and d042c5a26452797afc4fe8c2ceddebff94d88745, but I suspect that 32-bit support has generally been on the wane for some time
