Message-ID: <tip-fb50b020c5331c8c4bee0eb875865f5f8be6c03a@git.kernel.org> Date: Fri, 16 Nov 2012 16:49:36 -0800 From: tip-bot for Alexander Duyck <alexander.h.duyck@...el.com> To: linux-tip-commits@...r.kernel.org Cc: linux-kernel@...r.kernel.org, hpa@...or.com, mingo@...nel.org, yinghai@...nel.org, alexander.h.duyck@...el.com, tglx@...utronix.de, hpa@...ux.intel.com, daniel@...ascale-asia.com Subject: [tip:x86/mm] x86: Move some contents of page_64_types.h into pgtable_64.h and page_64.h Commit-ID: fb50b020c5331c8c4bee0eb875865f5f8be6c03a Gitweb: http://git.kernel.org/tip/fb50b020c5331c8c4bee0eb875865f5f8be6c03a Author: Alexander Duyck <alexander.h.duyck@...el.com> AuthorDate: Fri, 16 Nov 2012 13:53:09 -0800 Committer: H. Peter Anvin <hpa@...ux.intel.com> CommitDate: Fri, 16 Nov 2012 16:40:34 -0800 x86: Move some contents of page_64_types.h into pgtable_64.h and page_64.h This patch is meant to clean-up the fact that we have several functions in page_64_types.h which really don't belong there. I found this issue when I had tried to replace __phys_addr with an inline function. It resulted in the realmode bits generating compile warnings about types. In order to resolve that I am relocating the address translation to page_64.h since this is in keeping with where these functions are located in 32 bit. In addtion I have relocated several functions defined in init_64.c to pgtable_64.h as this seems to be where most of the functions related to memory initialization were already located.
