Xishi Qiu c072b90c8d x86/mm: Fix zone ranges boot printout ...

This is the usual physical memory layout boot printout:
	...
	[    0.000000] Zone ranges:
	[    0.000000]   DMA      [mem 0x00001000-0x00ffffff]
	[    0.000000]   DMA32    [mem 0x01000000-0xffffffff]
	[    0.000000]   Normal   [mem 0x100000000-0xc3fffffff]
	[    0.000000] Movable zone start for each node
	[    0.000000] Early memory node ranges
	[    0.000000]   node   0: [mem 0x00001000-0x00099fff]
	[    0.000000]   node   0: [mem 0x00100000-0xbf78ffff]
	[    0.000000]   node   0: [mem 0x100000000-0x63fffffff]
	[    0.000000]   node   1: [mem 0x640000000-0xc3fffffff]
	...

This is the log when we set "mem=2G" on the boot cmdline:
	...
	[    0.000000] Zone ranges:
	[    0.000000]   DMA      [mem 0x00001000-0x00ffffff]
	[    0.000000]   DMA32    [mem 0x01000000-0xffffffff]  // should be 0x7fffffff, right?
	[    0.000000]   Normal   empty
	[    0.000000] Movable zone start for each node
	[    0.000000] Early memory node ranges
	[    0.000000]   node   0: [mem 0x00001000-0x00099fff]
	[    0.000000]   node   0: [mem 0x00100000-0x7fffffff]
	...

This patch fixes the printout, the following log shows the right
ranges:
	...
	[    0.000000] Zone ranges:
	[    0.000000]   DMA      [mem 0x00001000-0x00ffffff]
	[    0.000000]   DMA32    [mem 0x01000000-0x7fffffff]
	[    0.000000]   Normal   empty
	[    0.000000] Movable zone start for each node
	[    0.000000] Early memory node ranges
	[    0.000000]   node   0: [mem 0x00001000-0x00099fff]
	[    0.000000]   node   0: [mem 0x00100000-0x7fffffff]
	...
