Subject: Huge buffer allocation: best place

Hi ml,

I need to allocate a huge contiguous buffer (~6MByte) shared with a secondary 
cpu (a packet processor). Which is the best place and the best way to do this?

The main problem is that using a simple kmalloc at module init time there 
isn't sufficient contiguous memory to cover the request. I should use (I 
suppose) the alloc_bootmem_* macros but I'm not sure where is the best place 
to reserve my memory.

For now I defined a global bad huge vector... but I'm not happy for this 
solution...

thanks in advance.

luigi
