2015-03-17 Thread Igor Mammedov
since commit dd0247e0 pc: acpi: mark all possible CPUs as enabled in SRAT Linux kernel actually tries to use CPU to Node mapping from QEMU provided SRAT table instead of discarding it, and that in some cases breaks build_sched_domains() which expects sane mapping where cores/threads belonging to
