Subject: [PATCH] 2008-08-08  Robert Millan  <rmh@aybabtu.com>

        * kern/disk.c: Replace `<grub/machine/time.h>' with `<grub/time.h>'.
        (grub_last_time): Change type to grub_uint64_t.
        (grub_disk_open): Migrate code from to using grub_get_time_ms().
        (grub_disk_close): Likewise.

        * normal/menu.c: Replace `<grub/machine/time.h>' with `<grub/time.h>'.
        (run_menu): Migrate code from to using grub_get_time_ms().

        * util/misc.c (grub_get_time_ms): New function.
