The last artifacts.ci kernel.txz content to boot 2-socket G4's correctly seems to be: -r361494

A quick summary of what I found in a crude artifact bisect is coded into
the filenames listed later. The earliest major point is the "1 CPUs woken"
issue from what I can tell. It still happens in -r368820 .
"2cpus_booted" means things booted and worked normally.
"1cpuwoke_" means that the following was reported:
SMP: 2 CPUs found; 2 CPUs usable; 1 CPUs woken
"_hung" means that it appeared to stop without reporting a crash. Never
got to login prompt.
"crashes_quickly" means that the the kernel did not get very far before
the crash happened.
-rw-r--r-- 1 root wheel 19179328 May 25 21:44:01 2020 kernel-r361494-2cpus_booted.txz
Note: No artifact kernel.txz files for the range -r361495 .. -r361583 .
powerpc checkins in that range include:
-r361542 : [PowerPC] Fix invalid asm in trap code (Brandon)
-r361544 : powerpc/mmu: Convert PowerPC pmap drivers to ifunc from kobj (Justin)
-r361545 : Properly sort ifdef archs in vm_fault_soft_fast superpage guards. (Justin)
-r361568 : [PowerPC] Fix radix crash when passing -1 from userspace (Brandon)
-r361570 : powerpc/pmap: Remove some debug from r361544 (Justin)

NOTE: -r364284 is where clang 11 started and the -O newly meaning -O1 problem started.
(Previously -O meant -O2. -O1 messed up the kernel's ifunc handling until it
was changed to explicitly use -O2.)

Note: -r368820 still has "1cpuwoke" status and its USB is messed up (and
it reports DMA misalignment) but it does boot. (I accessed it via ssh.)
