x86/boot: Add missing bootparam that breaks boot on some platforms
Change
a90118c445cc x86/boot: Save fields explicitly, zero out everything else
modified the way boot parameters were saved on x86. When this was
backported, e820_table didn't exists, and that change was dropped.
Unfortunately, e820_table did exist, it was just named e820_map
in this kernel version.
This was breaking booting on a Supermicro Super Server/A2SDi-2C-HLN4F
with a Denverton CPU. Adding e820_map to the saved boot params table
fixes the issue.
