Subject[PATCH] x86/numa_emulation: fix parsing of numa_meminfo for uniform numa emulation
From
Date
During fakenuma processing in numa_emulation(), pi gets passed in and
processed as new fake numa nodes are being split out. Once the original
memory region is proccessed, it gets removed from the pi by
numa_remove_memblk_from() in emu_setup_memblk(). So entry 0 gets deleted
and the rest of the entries get moved up. Therefore we should always pass
in entry 0 for the next entry to process.

Fixes: 1f6a2c6d9f121 ("x86/numa_emulation: Introduce uniform split
capability")
