* stage2/asm.S [!STAGE1_5] (linux_text_len): New variable.
[!STAGE1_5] (linux_boot): Don't set %eax to LINUX_SETUP
meaninglessly.
Set %ecx to LINUX_TEXT_LEN instead of LINUX_KERNEL_MAXLEN.
[!STAGE1_5] (big_linux_boot): Disable interrupts before changing
the stack pointer.
Change %ss right before %sp.
Reverse the arguments for ljmp. A segment must be after an
offset. *sigh*
* stage2/boot.c (load_image): Set LINUX_TEXT_LEN to TEXT_LEN,
if a Linux kernel is loaded successfully.
* stage2/shared.h (LINUX_VID_MODE_OFFSET): Removed.
[!ASM_FILE] (linux_kernel_header): Change the type of the member
`heap_end_ptr' to unsigned short.
[!ASM_FILE] (linux_text_len): Declared.

Comply with the Linux/i386 boot protocol version 2.02.
