+ * Changelog:
+ *
+ * 17 May 2004 - Matt Domsch <Matt_Domsch@dell.com>
+ * remove check for efi_enabled in exit
+ * add MODULE_VERSION
+ *
+ * 26 Apr 2004 - Matt Domsch <Matt_Domsch@dell.com>
+ * minor bug fixes
+ *
+ * 21 Apr 2004 - Matt Tolentino <matthew.e.tolentino@intel.com)
+ * converted driver to export variable information via sysfs
+ * and moved to drivers/firmware directory
+ * bumped revision number to v0.07 to reflect conversion & move
+ *
+ * 10 Dec 2002 - Matt Domsch <Matt_Domsch@dell.com>
+ * fix locking per Peter Chubb's findings
+ *
+ * 25 Mar 2002 - Matt Domsch <Matt_Domsch@dell.com>
+ * move uuid_unparse() to include/asm-ia64/efi.h:efi_guid_unparse()
+ *
+ * 12 Feb 2002 - Matt Domsch <Matt_Domsch@dell.com>
+ * use list_for_each_safe when deleting vars.
+ * remove ifdef CONFIG_SMP around include <linux/smp.h>
+ * v0.04 release to linux-ia64@linuxia64.org
+ *
+ * 20 April 2001 - Matt Domsch <Matt_Domsch@dell.com>
+ * Moved vars from /proc/efi to /proc/efi/vars, and made
+ * efi.c own the /proc/efi directory.
+ * v0.03 release to linux-ia64@linuxia64.org
+ *
+ * 26 March 2001 - Matt Domsch <Matt_Domsch@dell.com>
+ * At the request of Stephane, moved ownership of /proc/efi

+ *
+ * 12 March 2001 - Matt Domsch <Matt_Domsch@dell.com>
+ * Feedback received from Stephane Eranian incorporated.
+ * efivar_write() checks copy_from_user() return value.
+ * efivar_read/write() returns proper errno.
+ * v0.02 release to linux-ia64@linuxia64.org
+ *
+ * 26 February 2001 - Matt Domsch <Matt_Domsch@dell.com>
