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] ...
