[linux-dvb] saa7146_core.c won't work on systems with more than 1GB RAM

Hi all,

I've got a system with 1GB of RAM and I updated my dvb-kernel directory from 
CVS and found that this bit of code at line 119 of  
linux/drivers/media/common/saa7146_core.c causes an Oops each time I try to 
load the driver:

      if (PageHighMem(pg))
                BUG();

In other words, if you've got more than a gig and your kernel (I'm running the 
Mandrake 9.0 contrib'd Multimedia kernel which includes pre-empt patches) 
happens to decide to use that memory for paging then you're stuffed.

Commenting it out (along with a couple of similar tests in 
build-2.4/video-buf.c doesn't seem to cause any problems for me, so it'd be 
nice if it could be made conditional on something so I don't need to keep 
re-patching if I upgrade from CVS again!

cheers,
Chris
