From e957f608f321a97a60d065bccd01949590eef52e Mon Sep 17 00:00:00 2001 From: Grant Grundler Date: Tue, 23 Jun 2009 11:03:11 -0400 Subject: [PATCH] parisc: Fix gcc 4.4 warning in lba_pci.c gcc 4.4 warns about: drivers/parisc/lba_pci.c: In function 'lba_pat_resources': drivers/parisc/lba_pci.c:1099: warning: the frame size of 8280 bytes is larger than 4096 bytes The problem is we declare two large structures on the stack. They don't need to be on the stack since they are only used during LBA initialization (which is serialized). Moving to be "static".
