You're assuming I've control over the bootloader.

That code is not sufficient.

It's a placeholder for something I'd like to implement for the FR451 CPU which
has a decrementer counter. It is actually called from entry.S.

It's called "flag" in include/asm-i386/dma-mapping.h. And shouldn't it be an
"unsigned long" if it's GFP flags?

I'm not sure whether it should put all of its memory in the DMA region, or
none of it. There's no documentation on this.

Should I then add an arch-specific file to "/proc/<pid>/"?
