Subject: How to guarantee that kmalloc returns an address below 4GB

Hey,

is there an option for kmalloc, which I can use to allocate a buffer which is in physical memory placed below 4GB?
Not in a remapped area.
The only way I found is to use GFP_DMA, but this says the first 16MB isn't it?

Ciao Thilo
