Message-ID: <20120427233741.25317.28858.stgit@bhelgaas.mtv.corp.google.com>
Date: Fri, 27 Apr 2012 17:37:41 -0600
From: Bjorn Helgaas <bhelgaas@...gle.com>
To: Andrew Morton <akpm@...ux-foundation.org>, x86@...nel.org
Cc: Yinghai Lu <yinghai@...nel.org>, linux-kernel@...r.kernel.org,

Subject: [PATCH 2/4] x86: print physical addresses consistently with other
parts of kernel
Print physical address info in a style consistent with the %pR style used
elsewhere in the kernel. For example:
-found SMP MP-table at [ffff8800000fce90] fce90
+found SMP MP-table at [mem 0x000fce90-0x000fce9f] mapped at [ffff8800000fce90]
-initial memory mapped : 0 - 20000000
+initial memory mapped: [mem 0x00000000-0x1fffffff]
-Base memory trampoline at [ffff88000009c000] 9c000 size 8192
+Base memory trampoline [mem 0x0009c000-0x0009dfff] mapped at [ffff88000009c000]
-SRAT: Node 0 PXM 0 0-80000000
+SRAT: Node 0 PXM 0 [mem 0x00000000-0x7fffffff]
