* conf/i386-pc.rmk (kernel_img_SOURCES): Add `kern/i386/pit.c'.
        * conf/i386-efi.rmk (kernel_mod_SOURCES): Likewise.
        * conf/i386-coreboot.rmk (kernel_elf_SOURCES): Likewise. Also add
        `kern/i386/tsc.c', `kern/generic/rtc_get_time_ms.c' and
        `kern/generic/millisleep.c'.

        * kern/i386/tsc.c (calibrate_tsc): Rewrite using grub_pit_wait()
        instead of grub_get_rtc().
        (grub_tsc_init): Initialize `tsc_boot_time'.

        * kern/i386/linuxbios/init.c (grub_millisleep): Remove stub.
        (grub_machine_init): Use grub_tsc_init() rather than
        installing an RTC-based handler via grub_install_get_time_ms().

        * kern/i386/pit.c: New file.
        * include/grub/i386/pit.h: Likewise.
