m68k_num_memory is unsuitable to test for the presence of FastRAM
on CT60 if the kernel is located in FastRAM: in arch/m68k/mm/motorola.c
the ST-RAM chunk is skipped and m68k_num_memory is decremented in this
case. m68k_realnum_memory still contains the actual number of RAM chunks
so use that.
Tested by Christian Steiges on his Falcon with kernel loaded in FastRAM
- could you please reply with your Tested-by tag, Christian?
