A Toshiba CB35 Chromebook running Google's stock SeaBIOS reboots after selecting a relocatable kernel from extlinux 6.03. This is a regression caused by commit 8f470e7b movebits: Add syslinux_memmap_find() which factors syslinux_memmap_find() out of bios_boot_linux(). Prior to the refactoring, prot_mode_size was passed as the length in the first call to syslinux_memmap_type(). After the refactoring, hdr.init_size was passed. Now, with commit ef81a3ad, one...

If the kernel is relocatable and the protected mode code will not fit in the initially determined location, that code will be moved to the next available location. However, beginning with commit 8f470e7b, the code is moved to the initially determined location instead of the next available location because prot_mode_base is no longer updated to the correct location. Since whdr->code32_start is updated, it is pointing to the wrong execution start location, random code is executed and the machine i...

Correct base's type to match its initialization from prot_mode_base and passage to syslinux_memmap_find(). Tested with extlinux.
