Re: POWER6 not seeing memory above 2Gb

[Gasha <gasha@pie-dabas.net>]

With 3 Gb assigned to LPAR (p7) it looks correct:

gasha@power:~$ dmesg | grep Memory [ 0.000000] physicalMemorySize = 
0xc0000000 [ 0.000000] Node 0 Memory: 0x0-0xc0000000 [ 0.000000] Memory: 
2811776K/3145728K available (7360K kernel code, 1792K rwdata, 1840K 
rodata, 960K init, 2071K bss, 333952K reserved)
