* [PATCH] percpu: fix pcpu_last_unit_cpu 2010-09-21 0:40 ` CAI Qian @ 2010-09-21 6:13 ` Tejun Heo -1 siblings, 0 replies; 8+ messages in thread From: Tejun Heo @ 2010-09-21 6:13 UTC (permalink / raw) To: CAI Qian, lkml Cc: graff yang, Marcelo Tosatti, kexec, linux-kernel, dhowells, sonic adi, Chris Lalancette, Avi Kivity pcpu_first/last_unit_cpu are used to track which cpu has the first and last units assigned. This in turn is used to determine the span of a chunk for man/unmap cache flushes and whether an address belongs to the first chunk or not in per_cpu_ptr_to_phys(). When the number of possible CPUs isn't power of two, a chunk may contain unassigned units towards the end of a chunk. The logic to determine pcpu_last_unit_cpu was incorrect when there was an unused unit at the end of a chunk. It failed to ignore the unused unit and assigned the unused marker NR_CPUS to pcpu_last_unit_cpu. This was discovered through kdump failure which was caused by malfunctioning per_cpu_ptr_to_phys() on a kvm setup with 50 possible CPUs by CAI Qian.
