sparsemem: on no vmemmap path put mem_map on node high too
We need to put mem_map high when virtual memmap is not used.
before this patch
free mem pfn range on first node:
[ 0.000000] 19 - 1f
[ 0.000000] 28 40 - 80 95
[ 0.000000] 702 740 - 1000 1000
[ 0.000000] 347c - 347e
[ 0.000000] 34e7 3500 - 3b80 3b8b
[ 0.000000] 73b8b 73bc0 - 73c00 73c00
[ 0.000000] 73ddd - 73e00
[ 0.000000] 73fdd - 74000
[ 0.000000] 741dd - 74200
[ 0.000000] 743dd - 74400
[ 0.000000] 745dd - 74600
[ 0.000000] 747dd - 74800
[ 0.000000] 749dd - 74a00
[ 0.000000] 74bdd - 74c00
[ 0.000000] 74ddd - 74e00
[ 0.000000] 74fdd - 75000
[ 0.000000] 751dd - 75200
[ 0.000000] 753dd - 75400
[ 0.000000] 755dd - 75600
[ 0.000000] 757dd - 75800
[ 0.000000] 759dd - 75a00
[ 0.000000] 79bdd 79c00 - 7d540 7d550
[ 0.000000] 7f745 - 7f750
[ 0.000000] 10000b 100040 - 2080000 2080000
so only 79c00 - 7d540 are major free block under 4g...
after this patch, we will get
[ 0.000000] 19 - 1f
[ 0.000000] 28 40 - 80 95
[ 0.000000] 702 740 - 1000 1000
[ 0.000000] 347c - 347e
[ 0.000000] 34e7 3500 - 3600 3600
[ 0.000000] 37dd - 3800
[ 0.000000] 39dd - 3a00
[ 0.000000] 3bdd - 3c00
[ 0.000000] 3ddd - 3e00
[ 0.000000] 3fdd - 4000
[ 0.000000] 41dd - 4200
[ 0.000000] 43dd - 4400
[ 0.000000] 45dd - 4600
[ 0.000000] 47dd - 4800
[ 0.000000] 49dd - 4a00
[ 0.000000] 4bdd - 4c00
[ 0.000000] 4ddd - 4e00
[ 0.000000] 4fdd - 5000
[ 0.000000] 51dd - 5200
[ 0.000000] 53dd - 5400
[ 0.000000] 95dd 9600 - 7d540 7d550
[ 0.000000] 7f745 - 7f750
[ 0.000000] 17000b 170040 - 2080000 2080000
we will have 9600 - 7d540 for major free block...
