Could you check up on CONFIG_HAVE_ARCH_BOOTMEM use in bootmem.c too?
x86 no longer uses bootmem.c
avr define it - but to n.

So no-one is actually using this anymore.
I have sent patches to remove it from Kconfig for both x86 and avr.

I looked briefly at cleaning up bootmem.c myslef - but I felt not
familiar enough with the code to do the cleanup.

I did not check your patchset - but based on the shortlog you
did not kill HAVE_ARCH_BOOTMEM.
