Previously the setup_header length was just assumed to be the size of the linux_kernel_params struct. The linux x86 32-bit boot protocol says that the end of the linux_i386_kernel_header is at 0x202 + the byte value at 0x201 in the linux_i386_kernel_header. So, calculate the size of the header using the end of the linux_i386_kernel_header, rather than assume it is the size of the linux_kernel_params struct. Additionally, add some required members to the linux_kernel_params struct and align the content of linux_i386_kernel_header struct with it. New members naming was taken directly from Linux kernel source. linux_kernel_params and linux_i386_kernel_header structs require more cleanup. However, this is not urgent, so, let's do this after release. Just in case...

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
