Am I correct that intermediate commits in this patchset (i.e. bisection)
may not work correctly, since bootmem will have been stripped out but
NO_BOOTMEM=n and memblock may not be properly operational yet?

If so, is there a way to switch without breaking bisection that doesn't
involve squashing most of the series into a single atomic commit?

Cheers
