From 103018aca2e4ba0d0e230efa864231c59228f419 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Thu, 28 Feb 2008 09:38:44 -0800 Subject: [PATCH] [WATCHDOG] Fix declaration of struct smbios_entry_point in hpwdt On my HP DL380 G5 system running a 64-bit kernel, loading the hpwdt driver causes a crash because the driver attempts to ioremap an invalid physical address. This is because the driver has an incorrect definition of the SMBIOS table entry point structure: the table address is only a 32-bit quantity, and making it a u64 means that the high-order 32 bits end up containing garbage. Correcting the structure definition fixes the driver so that it loads without any problems on my system.
