From 09c17eab075ceeafb53935d858c575b6776394d1 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Mon, 28 Feb 2011 16:01:09 -0500 Subject: arch/tile: add some more VMSPLIT options and use consistent naming This renames 3G_OPT to 2_75G, and adds 2_5G and 2_25G. For memory-intensive applications that are also network-buffer intensive it can be helpful to be able to tune the virtual address of the start of kernel memory.
