Hello all,

We have PPC board which runs on linux kernel. When I looked at dmesg, 
the memory ZONES were divided as below

768MB for ZONE_DMA
256MB for ZONE_HIGHMEM
ZONE_NORMAL is not present.

Now what does this mean? Is that kernel space entirely mapped to 
ZONE_DMA? Does user process get only 256MB of physical memory? I am 
pretty much confused about these zones.

Is this particular to only PPC architecture?

Kindly clarify

Thanks in advance
Heramba
