imp, asomers: could you help check this? All these changes are looking innocent to me, but all the following test failed.

I'll investigate. I agree that none of the changes look relevant.
This turns out not to be a gmultipath problem at all, but a dtrace problem. dtrace apparently fails if the kernel contains > 2^15 CTF entries. For some reason, the i386 CI test image contains 35,538. The only short-term solution would be to decrease the amount of stuff in the CI test image to reduce the CTF symbol count. Long-term solutions are under discussion in bug 232675. # ctfdump -S /boot/kernel/kernel | awk '$0~/of types/{print$6}' 35538 *** This bug has been marked as a duplicate of bug 232675 ***
I'll check what we can do for this test case. Reopen for tracking until it get reenabled.

The overloading of struct pmap for PAE and non-PAE pmaps results in three distinct layouts for the structure, which is embedded in struct vmspace. This causes a large number of duplicate structure definitions in the i386 kernel's CTF type graph. Since most pmap fields are the same in the two pmaps, simply provide side-by-side variants of the fields that are distinct, using fixed-size types.

There is nothing to MFC after all, stable/12 does not have the dual i386 pmap implementation that triggered this problem.
