[PATCH] FRV: Permit large kmalloc allocations [try #2]
From: David Howells
Date: Mon Oct 02 2006 - 12:27:23 EST
From: David Howells <dhowells@xxxxxxxxxx>
Permit kmalloc() to make allocations of up to 32MB if so configured. This may
be useful under NOMMU conditions where vmalloc() can't do this.

with a lot of RAM, this can be wasteful of precious low memory.
Setting this option will put user-space page tables in high memory.

+ Allow the slab memory allocator to keep chains for very large memory
