From 339b0c0813a257893fa84be999b9b85a50846dd8 Mon Sep 17 00:00:00 2001 From: David Howells Date: Tue, 3 Oct 2006 01:13:47 -0700 Subject: [PATCH] FRV: Permit large kmalloc allocations [try #2] 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.
