From 649de51b883746d76c5fa1614dd067054c9d702a Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Fri, 2 May 2008 21:17:06 +0100 Subject: [ARM] 5027/1: Fixed random memory corruption on pxa suspend cycle. Each time a pxa type cpu went in suspend, a portion of kmalloc memory was corrupted. The issue was an incorrect length allocation introduced by the commit 711be5ccfe9a02ba560aa918a008c31ea4760163 for the save registers array (=> overflow).
