From d61e16df940e02e25679bdc1aee8c25786f6de90 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 17 Mar 2006 17:33:56 -0800 Subject: [SPARC64]: Increase top of 32-bit process stack. Put it one page below the top of the 32-bit address space. This gives us ~16MB more address space to work with. Signed-off-by: David S.
