[PATCH 10/50] x86/boot/e820: Move HIGH_MEMORY define to asm/e820/types.h

From: Ingo Molnar
Date: Sat Jan 28 2017 - 19:11:29 EST


The HIGH_MEMORY define was in the API header, while it conceptually
belongs to the other physical memory ranges in the e820/types.h
header.

Move it there - and also convert the 1MB address to hexa, so that
it lines up more nicely with the other memory address values.

No change in functionality.
