From a62e2f4f508863da8e0c2f2b42f5252a87330297 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 29 May 2012 15:06:30 -0700 Subject: mm: 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: -Zone PFN ranges: +Zone ranges: - DMA32 0x00000010 -> 0x00100000 + DMA32 [mem 0x00010000-0xffffffff] - Normal 0x00100000 -> 0x01080000 + Normal [mem 0x100000000-0x107fffffff] Signed-off-by: Bjorn Helgaas Cc: Yinghai Lu Cc: Konrad Rzeszutek Wilk Cc: Ingo Molnar Cc: "H.
