of PUPA_CHAINLOADER_BOOT_SECTOR.
* kern/i386/pc/startup.S: Include pupa/machine/linux.h.
(pupa_linux_prot_size): New variable.
(pupa_linux_tmp_addr): Likewise.
(pupa_linux_real_addr): Likewise.
(pupa_linux_boot_zimage): New function.
(pupa_linux_boot_bzimage): Likewise.
* kern/i386/pc/init.c (struct mem_region): New structure.
(MAX_REGIONS): New macro.

(compact_mem_regions): Likewise.
(pupa_machine_init): Set PUPA_LOWER_MEM and PUPA_UPPER_MEM to
the size of the conventional memory and that of so-called upper
memory (before the first memory hole).
Instead of adding each found region to free memory, use
add_mem_region and add them after removing overlaps.
Also, add only 1/4 of the upper memory to free memory. The rest
is used for loading OS images. Maybe this is ad hoc, but this
makes it much easier to relocate OS images when booting.
* kern/rescue.c (pupa_rescue_cmd_module): Removed.
(pupa_enter_rescue_mode): Don't register initrd and module.
* kern/mm.c: Include pupa/dl.h.

module is too dangerous.
* include/pupa/loader.h (pupa_os_area_addr): Declared.
(pupa_os_area_size): Likewise.
(pupa_loader_set): Remove the first argument. Loader doesn't
manage modules or initrd any longer.

rmmod and lsmod.
* kern/mm.c (pupa_memalign): If failed even after invalidating
disk caches, unload unneeded modules and retry.
* kern/misc.c (pupa_memmove): New function.
(pupa_memcpy): Removed.
(pupa_strcpy): New function.
(pupa_itoa): Made static.

pupa_memmove.
(pupa_memmove): Declared.
(pupa_strcpy): Likewise.
* include/pupa/dl.h (PUPA_MOD_INIT): Change the prototype. Now
pupa_mod_init takes one argument, its own module.
(pupa_dl_unload_unneeded): Declared.
(pupa_dl_unload_all): Likewise.
(pupa_dl_ref): Likewise.
(pupa_dl_unref): Likewise.
