Dan Carpenter 9245e019e5 kdb: do a sanity check on the cpu in kdb_per_cpu() ... [ Upstream commit b586627e10f57ee3aa8f0cfab0d6f7dc4ae63760 ] The "whichcpu" comes from argv[3]. The cpu_online() macro looks up the cpu in a bitmap of online cpus, but if the value is too high then it could read beyond the end of the bitmap and possibly Oops.
