Some filesystems nowadays use 64-bit types for timestamps. So, update grub_dirhook_info struct to use an grub_int64_t type to store mtime. This also updates the grub_unixtime2datetime() function to receive a 64-bit timestamp argument and do 64-bit-safe divisions. All the remaining conversion from 32-bit to 64-bit should be safe, as 32-bit to 64-bit attributions will be implicitly casted. The most critical part in the 32-bit to 64-bit conversion is in the function grub_unixtime2datetime() where it needs to deal with the 64-bit type. So, for that, the grub_divmod64() helper has been used. These changes enables the GRUB to support dates beyond y2038.

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
