Subject: [PATCH v2 0/3] m68k: switch to MEMBLOCK + NO_BOOTMEM

Hi,

These patches switch m68k boot time memory allocators from bootmem to
memblock + no_bootmem.

The first two patches update __ffs() and __va() definitions to be inline
with other arches and asm-generic. This is required to avoid compilation
warnings in mm/memblock.c and mm/nobootmem.c.

The third patch performs the actual switch of the boot time mm. Its
changelog has detailed description of the changes.

I've tested the !MMU version with qemu-system-m68k -M mcf5208evb
and the MMU version with q800 using qemu from [1].

I've also build tested allyesconfig and *_defconfig.

v2:
* fix reservation of the kernel text/data/bss for ColdFire MMU

Mike Rapoport (3):
  m68k/bitops: convert __ffs to match generic declaration
  m68k/page_no.h: force __va argument to be unsigned long
  m68k: switch to MEMBLOCK + NO_BOOTMEM
