From 99da1ffe0a85a727c368afa7fc21f7a740477aa4 Mon Sep 17 00:00:00 2001

Subject: [PATCH] x86/boot/e820: Split minimal UAPI types out into
 uapi/asm/e820/types.h

bootparam.h, which defines the legacy 'zeropage' boot parameter area,
requires a small amount of e280 defines in the UAPI space - provide them.

No change in functionality.
