As I did previously with v2 and v5 of the patch series, I tested in
Hyper-V guests on x86/x64 and arm64. Did basic smoke tests of taking
a CPU offline, and removing a PCI device along with its IRQs, then adding
them back again. Everything looks good. The improved alignment looks
100% good. The alignment nits I called out against v5 are fixed, and I
did not find anything new to be picky about.

I did not do anything with the new binary interface or the gdb Python
script.
