Subject: [patch 2/2] kill off highmem_start_page (in -mm)
Date: Wed, 17 Nov 2004 13:18:40 -0800 [thread overview]
Message-ID: <E1CUXCL-0006YD-00@kernel.beaverton.ibm.com> (raw)
This patch should fix kgdb to work without highmem_start_page.
However, I don't have a kgdb setup, and I'd appreciate someone
testing this to make sure my selection of a new variable is OK.
Also, should this function possibly be using system_state, instead?
