Yes, with both of those patches applies, the problem is solved:-)

I was going to test the second patch originally, but it sounded like it
was more of a cleanup rather than a fix for my issue, so I didn't bother
when I found the problem wasn't solved by patch 1. Sorry!

For the record, I'm testing on a 2-CPU system, so I'm not sure whether
your explanation applies; it talks about CPUs 2 and 3 whereas I only
have CPUs 0 and 1, but perhaps your explanation applies equally to any
pair of CPUs?

For the record, here's the information you requested in the other email:

# cat /sys/devices/system/cpu/cpu*/cpufreq/related_cpus
0 1
0 1
