From 979dca3826841e5dc9170c28f20bd75ece266a9a Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Fri, 19 May 2006 11:55:58 -0700 Subject: [PATCH] [SCSI] imm: no need for unchecked_isa_dma Relax the lowmem bounce buffer requirement for imm so that any low memory page will do -- they don't need to be below the ISA 16 MB limit, just need to be mapped in low memory.
