Himanshu Sahdev aka CunningLearner 2b84008ed9 arch/x86/bootblock_crt0.S: Leverage eax in protected mode entry 
Leverage already used eax register in bootblock_protected_mode_entry.
Avoid another register ebx just for preserving eax value as it is not
needed and is not used at all after moving the value into mm0.
Allow EBX to be preserved for other usage.
