From 7c63984b86f96c71c541132c74c4b56fe2a13e1a Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Thu, 23 Sep 2010 16:52:40 -0400 Subject: ARM: do not define VMALLOC_END relative to PAGE_OFFSET VMALLOC_END is supposed to be an absolute value, while PAGE_OFFSET may vary depending on the selected user:kernel memory split mode through CONFIG_VMSPLIT_*. In fact, the goal of moving PAGE_OFFSET down is to accommodate more directly addressed RAM by the kernel below the vmalloc area, and having VMALLOC_END move along PAGE_OFFSET is rather against the very reason why PAGE_OFFSET can be moved in the first place.

The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in. Updated with fixes for OMAP from Jason Wang and Tony Lindgren , and fix for versatile express from Lorenzo Pieralisi .
