From 78a904b65420e02bf964af6a83c1fd7a85e0b59d Mon Sep 17 00:00:00 2001 From: "Randy.Dunlap" Date: Fri, 19 May 2006 10:11:02 -0700 Subject: [PATCH] [SCSI] ppa: fix for machines with highmem ppa cannot handle highmem pages, and like imm, which already has this patch, the device is slow, so performance is not a big issue, so just force pages to be in low memory (hence mapped).
