From 9b987aeb4a7bc42a3eb8361030b820b0263c31f1 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Thu, 9 Apr 2009 10:55:33 -0700 Subject: x86: fix set_fixmap to use phys_addr_t Impact: fix kprobes crash on 32-bit with RAM above 4G Use phys_addr_t for receiving a physical address argument instead of unsigned long. This allows fixmap to handle pages higher than 4GB on x86-32.
