Commit-ID: 7b6e4ba3cb1ffdf84fc4d3775b922d64663ec6fc Gitweb: http://git.kernel.org/tip/7b6e4ba3cb1ffdf84fc4d3775b922d64663ec6fc Author: Ingo Molnar <mingo@xxxxxxxxxx> AuthorDate: Fri, 27 Jan 2017 11:46:14 +0100 Committer: Ingo Molnar <mingo@xxxxxxxxxx> CommitDate: Sat, 28 Jan 2017 09:31:14 +0100 x86/boot/e820: Clean up the E820_X_MAX definition E820_X_MAX is defined in a somewhat messy fashion: - there's a pretty pointless looking #ifndef __KERNEL__ define that makes no sense in the non-UAPI header anymore, - part of it is defined in api.h, which is not for type definitions, - plus it's defined in two headers and the main explanation is in the header where we don't have the real definition. So move it into a single place in e820/types.h and get rid of the !__KERNEL__ case altogether. Drop the smaller comment - the larger one explains it just fine. Note that the zeropage does not use E820_X_MAX, it uses the legacy 128 entries definition. No change in functionality.
