[PATCH] kdump: x86_64: add memmmap command line option
) From: Vivek Goyal <vgoyal@in.ibm.com> - This patch introduces the memmap option for x86_64 similar to i386. - memmap=exactmap enables setting of an exact E820 memory map, as specified by the user. Changes in this version: - Used e820_end_of_ram() to find the max_pfn as suggested by Andi kleen. - removed PFN_UP & PFN_DOWN macros - Printing the user defined map also.
